For trade installers, this is not about replacing uPVC. It is about having another product in your range that helps you meet different customer expectations.

Why Aluminium Casement Windows Are Growing in Demand

Homeowners are more design-aware than ever. Many are researching window styles before they speak to an installer, and they often come to the conversation already knowing they want something modern, slim and refined.

Aluminium casement windows fit this demand well. They offer a clean appearance, strong frame construction and slimmer sightlines compared with many traditional frame options.

Because aluminium is naturally strong, the frames can be slimmer while still delivering strength and stability. That means more glass, more natural light and a more contemporary look.

For installers, this gives you a clear upgrade option when customers want something that feels more premium than standard uPVC.

“We’re seeing more installers ask for aluminium because their customers are asking for a different look. It’s not always about replacing uPVC, it’s about giving installers another option when the project needs something more modern.”
Scott, Director at Nova Trade Frames

Where Aluminium Casement Windows Work Best

Aluminium casement windows are especially well suited to projects where appearance and performance both matter.

They work well on modern extensions, where homeowners want clean lines and larger glazed areas. They are also a good fit for new build homes, garden rooms, renovation projects and higher specification refurbishments.

In many cases, aluminium is chosen because the customer wants a more architectural finish. Darker colours such as anthracite grey and black are particularly popular on modern properties, especially when paired with bifold doors or sliding patio doors.

They can also work well on older homes where the customer wants to retain a slimmer, more refined look, depending on the style of frame and finish chosen.

A typical example would be an installer working on a rear extension in Nottinghamshire where the homeowner wants new windows to match aluminium patio doors. Rather than mixing materials, the installer can offer aluminium casement windows alongside the doors for a more consistent finish across the project.

How They Compare with uPVC Casement Windows

uPVC casement windows remain a very strong choice for many installations. They are practical, affordable and well established in the UK market.

Aluminium casement windows usually sit at a more premium level. They are often chosen for their appearance, strength and slim frame design.

The main difference is the look and feel of the finished installation. uPVC tends to be more cost conscious and familiar. Aluminium tends to feel sharper, slimmer and more design led.

That does not mean one is always better than the other. The right recommendation depends on the customer, the property and the budget.

If a homeowner wants a reliable, cost-effective replacement window, uPVC may still be the right choice. If they want a modern finish, slimmer sightlines and a more premium look, aluminium casement windows may be a better fit.

Key Benefits for Homeowners

For homeowners, aluminium casement windows offer several clear benefits.

The first is appearance. Slimmer frames create a cleaner look and allow more glass into the design. This can make rooms feel lighter and more open.

The second is durability. Aluminium is a strong material that performs well in everyday UK weather conditions. It does not warp or swell and is designed to provide long-term performance.

The third is thermal performance. Modern aluminium window systems use advanced thermal technology to help reduce heat loss and improve energy efficiency. This makes them suitable for modern projects where performance is just as important as appearance.

The fourth is flexibility. Aluminium casement windows are available in a wide range of colours and finishes, giving homeowners more choice when trying to match doors, roofline, cladding or other design features.

Key Benefits for Trade Installers

For trade installers, aluminium casement windows give you a useful upsell opportunity.

They allow you to offer a premium product to customers who want more than a standard window replacement. That can help increase the overall project value and position you as an installer who can offer wider product choice.

They also work well when customers are already choosing aluminium doors. If a homeowner is having aluminium bi-fold doors, patio doors or casement doors installed, matching aluminium windows can help create a more consistent overall finish.

From a practical point of view, working with the right supplier also matters. Installer-friendly features, clear specification, accurate manufacturing and good support all help reduce issues on site.

“A good aluminium window needs to look right for the homeowner, but it also needs to be practical for the installer. If it’s difficult to work with, that creates problems on site. That’s why we focus on systems that give both a strong finish and a sensible installation process.”
Scott, Director at Nova Trade Frames

What to Consider Before Quoting

Before quoting for aluminium casement windows, installers should consider the type of project, the customer’s expectations and the overall design.

Start with the customer’s reason for choosing aluminium. Are they focused on appearance, thermal performance, colour choice or matching existing aluminium doors?

Next, consider the glazing specification. Depending on the project, the customer may need double glazing, triple glazing, acoustic performance, laminated glass or specific thermal requirements.

Colour should also be confirmed early. Standard colours may be more straightforward, while special finishes or dual colour options may affect price and lead time.

It is also worth checking whether the customer wants a contemporary or more traditional look. Some aluminium casement windows can be configured with different sash styles, which helps match the product to the property.

Finally, make sure the product is suitable for the installation and complies with current building requirements.

Why Nova Supplies Aluminium Casement Windows for Trade

Nova has introduced aluminium casement windows to give trade customers more choice alongside its established uPVC range.

The aim is simple. Installers should be able to offer the right product for the right project, whether that is uPVC for everyday replacement work or aluminium for more premium installations.

Nova’s aluminium casement windows are designed for trade installers, with made-to-measure manufacturing, strong thermal performance and a modern finish. The range also works well alongside Nova’s aluminium doors, helping installers offer a consistent product package across windows and doors.

As with the wider Nova range, the focus remains on reliable supply, clear communication and trade support.

“We’ve always supported installers with uPVC, and aluminium is the next step. It gives our customers more choice, but the way we support them stays the same.”
Scott, Director at Nova Trade Frames

Final Thoughts

Aluminium casement windows are becoming an increasingly useful option for trade installers.

They are modern, strong, thermally efficient, and well-suited to projects where the customer wants a more premium finish. They will not replace uPVC on every job, and they do not need to. Instead, they give installers another option when the project calls for something slimmer, sharper and more design-focused.

For trade installers, offering aluminium casement windows can help you win different types of work, support higher value projects and give customers a wider choice.

If you are quoting for aluminium casement windows and want help with product options, specification or pricing, speak to the Nova team today.

But not every aluminium patio door is the same.

Two of the most common options are inline aluminium patio doors and lift and slide aluminium patio doors. Both are sliding door systems, both offer modern styling, and both can work well on residential projects. However, they are suited to slightly different uses.

In this guide, we’ll explain the difference between the two, where each option works best, and what trade installers should consider before quoting.

Why Aluminium Patio Doors Are in Demand

Homeowners are increasingly looking for ways to bring more light into their homes and create a better connection between indoor and outdoor spaces. This is especially true on rear extensions, kitchen diners, garden rooms and open plan living areas.

Aluminium patio doors are well suited to this demand because they offer slim sightlines, large glass areas and a clean, contemporary appearance.

Compared with many traditional uPVC patio doors, aluminium allows for slimmer frames because the material is naturally strong. This means more glass and less visible frame, which is often exactly what homeowners are looking for.

For installers, this gives you a clear selling point. Aluminium patio doors allow you to offer a more premium option without moving into overly complicated product territory.

What Are Inline Aluminium Patio Doors?

Inline aluminium patio doors are sliding doors where the panels move along a track in a straightforward sliding action.

They are a practical choice for many domestic projects because they are simple, space-saving and easy for homeowners to use. They work particularly well where the customer wants a clean sliding door solution without needing the extra heavy-duty operation of a lift and slide system.

Inline aluminium patio doors are often used on standard rear openings, garden access points, extensions and properties where space is limited.

Because the doors slide rather than swing open, they do not take up room inside or outside the property. This makes them useful for patios, smaller gardens and tighter layouts.

What Are Lift and Slide Aluminium Patio Doors?

Lift and slide aluminium patio doors are designed for larger openings and heavier panels.

The main difference is in the operation. When the handle is turned, the door panel lifts slightly away from the track, allowing it to slide more smoothly. When closed, it lowers back into place, helping create a strong seal.

This makes lift and slide doors a good option for wider glazed openings where homeowners want large panels, smooth operation and a premium feel.

They are particularly suited to higher value projects where the customer wants maximum glass, strong performance and an impressive finish.

Inline vs Lift and Slide: What Is the Difference?

Both systems provide a sliding aluminium patio door solution, but the right choice depends on the project.

Inline aluminium patio doors are usually the more straightforward option. They are ideal where the opening is more standard in size, the customer wants a practical sliding door, and the budget needs to remain controlled.

Lift and slide aluminium patio doors are more suited to larger openings and premium installations. They are designed to handle heavier panels and provide smoother operation across wider spans.

In simple terms, inline patio doors are a strong everyday aluminium sliding door option. Lift and slide patio doors are better suited when the project demands larger glass panels, a more premium feel and enhanced operation.

Which Option Is Best for Different Projects?

For a standard rear replacement where the homeowner wants a modern upgrade from an older patio door, inline aluminium patio doors may be the right choice. They provide the slim look and durability of aluminium, while keeping the project practical and cost-effective.

For a new kitchen extension with a wide opening onto the garden, lift and slide aluminium patio doors may be more suitable. The larger the opening, the more important smooth operation and panel stability become.

For garden rooms, either option can work depending on the design. Inline doors are useful for smaller openings, while lift and slide doors can create a more premium feature.

For higher value renovations, lift and slide doors often give the homeowner the wow factor they are looking for.

The key is to match the product to the project, not simply quote the same option every time.

What Installers Should Consider Before Quoting

Before quoting for aluminium patio doors, installers should think about more than just the size of the opening.

The first question is how the doors will be used. Will they be opened daily, or are they mainly there to bring light into the room? Is the customer looking for a practical replacement, or are they trying to create a high-end feature?

The second consideration is the size and weight of the panels. Larger panels need a system designed to operate smoothly and reliably over time.

The third consideration is threshold choice. Some customers may want easier access between the house and garden, while others may prioritise weather performance.

Glazing should also be considered carefully. Larger glass areas may require specific glazing options depending on performance, safety and customer preference.

Finally, installers should consider what the customer values most. If they want a cost-effective aluminium upgrade, inline may be the best fit. If they want a premium sliding door system for a larger opening, lift and slide may be the better recommendation.

Why Nova Supplies Both Options

Nova supplies both inline aluminium patio doors and lift and slide aluminium patio doors because trade installers need flexibility.

Not every project is the same. Some customers want a practical sliding aluminium door for a standard opening. Others want a premium system for a larger extension or high-end renovation.

By offering both options, Nova helps installers match the right product to the right project.

It also means you can access aluminium patio doors alongside Nova’s wider range of uPVC and aluminium windows and doors, keeping more of your supply under one roof.

As a trade-focused supplier, Nova understands that installers need reliable lead times, clear communication and products that are made to specification. That support matters, especially when quoting more premium aluminium products.

Final Thoughts

Aluminium patio doors are a strong option for trade installers who want to offer customers a modern, premium and practical solution.

Inline aluminium patio doors are ideal for straightforward sliding door projects where space-saving operation and modern styling are important.

Lift and slide aluminium patio doors are better suited to larger openings, heavier panels and more premium installations.

Both have a place, and the best choice depends on the property, the customer and the overall project brief.

If you are quoting for aluminium patio doors and want help choosing the right option, speak to the Nova team today. We can help you compare the options, confirm the specification and get your customer the right product for the job.

But when it comes to quoting, one of the first questions customers usually ask is simple: how much do aluminium bi-fold doors cost?

The honest answer is that aluminium bifold doors prices can vary depending on a number of factors. Size, number of panels, colour, glazing, threshold choice, hardware and specification can all affect the final price.

For trade installers, understanding these factors makes it easier to quote accurately, explain value to customers and avoid pricing mistakes.

Why Aluminium Bifold Doors Are a Premium Product

Aluminium bi-fold doors usually sit at the more premium end of the window and door market. Compared with standard uPVC options, aluminium offers slimmer sightlines, stronger frames and a more modern overall finish.

Because aluminium is naturally strong, it allows for larger glass areas and slimmer frames. This is one of the biggest selling points for homeowners. They get more natural light, better views and a cleaner look.

Modern aluminium systems also offer strong thermal performance, smooth operation and a durable finish that works well on both contemporary and traditional properties.

For installers, this means aluminium bi-fold doors can help position a project as higher value. They are not always the cheapest option, but they often deliver the look and performance customers are willing to pay more for.

Size and Number of Panels

One of the biggest factors affecting aluminium bifold doors prices is the size of the opening.

A smaller two-panel bi-fold door will cost less than a wider four, five or six-panel system. That is because larger openings require more material, more glass, more hardware and more manufacturing time.

The number of panels also matters. Each additional panel adds cost, but it also changes how the doors operate. Some customers may want a traffic door for everyday access, while others may prefer a full opening system that folds back completely.

For installers, it is important to understand how the door configuration affects both price and usability. The cheapest configuration is not always the best option for the customer’s lifestyle or property.

Colour and Finish Options

Colour choice can also affect the final price.

Standard colours are often more cost-effective, while specialist colours or dual colour options may increase the cost. Anthracite grey, black and white remain popular choices because they suit modern extensions and garden rooms particularly well.

The finish matters too. Powder-coated aluminium provides a durable, clean appearance that is designed to stand up to everyday use and weather exposure.

When quoting, installers should always confirm the customer’s preferred colour early. This avoids surprises later and helps keep the quote accurate from the start.

Glazing Specification

Glazing is another key factor in aluminium bi-fold door pricing.

Most homeowners expect good energy performance as standard, but some projects may require upgraded glazing. This could include toughened glass, laminated glass, solar control glass or acoustic glass, depending on the property and how the space will be used.

Larger panes of glass can also affect cost because they require careful handling and stronger overall specification.

For trade installers, glazing should never be treated as an afterthought. It affects price, performance, compliance and the finished customer experience.

Thresholds, Hardware and Security

The smaller details can also influence aluminium bifold doors prices.

Threshold choice is a good example. Some customers may want a low threshold for easier access between the house and garden. Others may prioritise weather performance, depending on where the doors are being installed.

Hardware also matters. Handles, locking systems, hinges, rollers and security features all play a part in how the finished doors look, feel and perform.

This is where product quality becomes important. A cheaper bi-fold door system might look acceptable at first, but poor hardware or rough operation can quickly lead to complaints.

Modern premium systems, such as Sheerline aluminium profiles, are designed to give installers and homeowners confidence in both performance and usability.

Supply Only vs Supply and Fit

For trade installers, supply only aluminium bi-fold doors can be a strong option.

With supply only, you are in control of the installation, customer relationship and labour pricing. You can quote the job your way and protect your margin.

This can be especially useful when working with homeowners who already trust you to manage the full project. Rather than sending them to a retail supplier, you can source the product through a trade supplier and keep control of the process.

Nova supplies aluminium bi-fold doors for trade installers on a supply only basis, helping you access the right products while keeping the installation in your hands.

Why Installers Should Avoid Quoting on Price Alone

It can be tempting to focus purely on the lowest price, especially when customers are comparing quotes. But with aluminium bi-fold doors, the cheapest option is not always the best value.

Poor quality doors can lead to fitting issues, stiff operation, weaker thermal performance and customer complaints. Delays can also cost installers money if projects are held up or return visits are needed.

A better approach is to explain the value clearly. Homeowners are not just paying for a door. They are paying for the appearance, smooth operation, energy performance, security, durability and the confidence that the installation has been done properly.

For installers, using a reliable trade supplier helps protect both your quote and your reputation.

How Nova Helps Installers Quote with Confidence

At Nova Trade Frames, the aim is to make quoting and ordering straightforward for trade customers.

Nova’s aluminium range gives installers access to premium aluminium products alongside the uPVC windows, doors and conservatories they may already be ordering. This means you can offer customers more choice without needing to deal with multiple suppliers.

The team can help with quotes, product options and specification, making it easier to put together accurate pricing for your customer.

If you are already working with Nova, the aluminium range gives you another way to win higher value projects. If you are new to Nova, applying for a trade account gives you access to trade support, product guidance and a supplier that understands the needs of installers.

Final Thoughts

Aluminium bifold doors prices vary because every project is different. Size, panel configuration, colour, glazing, threshold, hardware and specification all affect the final cost.

For trade installers, the key is not just finding the cheapest product. It is finding the right balance between price, quality, reliability and support.

Aluminium bi-fold doors are a strong opportunity for installers who want to offer a more premium product to homeowners. With slim sightlines, smooth operation, modern styling and strong performance, they are well suited to today’s demand for larger, brighter living spaces.

If you are quoting for aluminium bi-fold doors and want support with pricing or specification, speak to the Nova team today.

But the market is changing.

More homeowners are asking for slimmer frames, larger openings, modern finishes and a more premium look.

Installers are being asked to provide products that feel contemporary, perform well and suit everything from extensions and renovations to garden rooms and new builds.

That is why Nova has now launched a new range of aluminium windows and doors for trade installers, manufactured using premium Sheerline aluminium profiles.

This new aluminium range gives our trade customers more choice, more flexibility and more ways to meet demand from homeowners who want something beyond standard uPVC

Why Aluminium Windows And Doors Are Becoming More Popular

uPVC is still a practical, cost-effective and reliable option for many homeowners. It performs well, is easy to maintain and remains one of the most popular choices in the UK.

However, aluminium offers a different type of finish.

For projects where appearance, scale and premium styling matter, aluminium has become increasingly popular. It gives homeowners the slim, modern look they often see in magazines, extensions, garden rooms and higher-end properties.

One of the biggest differences is the frame profile. Aluminium is naturally strong, which means the frames can be slimmer than traditional uPVC alternatives.

Slimmer sightlines mean more glass, more natural light and a cleaner overall appearance.

This is especially useful for larger openings, where homeowners want to connect living spaces with gardens, patios or outdoor areas.

For installers, this creates an opportunity.

Aluminium allows you to offer a more premium option to customers who want modern design, strong performance and a high-quality finish.

What Is Included in Nova’s New Aluminium Range?

Nova’s new aluminium range has been introduced to give trade installers a complete choice of modern window and door options.

The range includes:

Aluminium bi-fold doors, ideal for wide openings and open plan living spaces.

Lift and slide aluminium patio doors, designed for large glazed areas with smooth operation and a premium feel.

Inline aluminium patio doors are a practical sliding door option for homeowners who want space-saving access to gardens and patios.

Aluminium casement windows are a modern alternative to traditional window styles with slim frames and strong performance.

Aluminium flush casement windows, ideal for projects where a cleaner, more refined external finish is needed.

Aluminium casement doors, suitable for matching door and window projects where consistency matters.

This gives installers a more complete aluminium offering, without needing to source products from multiple suppliers.

Why Nova Has Chosen Sheerline Aluminium Profiles

Nova’s new aluminium range is manufactured using Sheerline aluminium profiles, a premium system designed to deliver the modern look homeowners want while also supporting the practical needs of trade installers.

Sheerline is known for its slim sightlines, strong thermal performance and high-quality finish.

This makes it a strong choice for installers who want to offer a more premium aluminium product alongside uPVC.

It has also been developed with installer-friendly features that help make fabrication and installation more straightforward.

For example, the system uses pre-gasketed clip-in beads, helping to remove the need for wedge gaskets or milled beads. This can help reduce complexity, improve consistency and save time during the manufacturing and fitting process.

Another important benefit is the ability to create internally beaded fixed lights using the reverse butt joint.

Internally beaded windows are widely preferred because they provide a cleaner appearance and offer additional security reassurance for homeowners.

For installers, this means a neater, more practical solution without relying on external glazing methods, reverse adaptors or dummy sashes.

For homeowners, it means a more consistent finish, a modern appearance and added confidence in the product.

In short, Sheerline gives Nova’s trade customers a premium aluminium system that looks good, performs well and has been designed with both the installer and end user in mind.

Aluminium vs uPVC: When Does Aluminium Make Sense?

This is not about saying aluminium is better than uPVC in every situation. Both have their place.

uPVC is still a great choice for many everyday projects. It is cost-effective, reliable, energy-efficient and low maintenance. For standard replacement windows, rental properties and budget-conscious projects, uPVC remains a strong option.

Aluminium makes sense when the customer wants something more premium.

It is particularly suited to:

• Modern extensions
• Large patio openings
• Garden rooms
• New build properties
• Higher value renovations
• Contemporary homes
• Projects where slim sightlines are important

The key benefit is appearance. Aluminium gives a sharper, more architectural look. The frames are slimmer, the glass areas can be larger and the overall finish feels more modern.

For trade installers, this means you can offer customers a choice. If they want practical and cost-effective, uPVC is there. If they want premium, modern and design-led, aluminium gives you another option.

Key Benefits of Aluminium Windows and Doors

Aluminium offers several benefits that make it attractive to both installers and homeowners.

Slim Sightlines

One of the biggest selling points of aluminium is the slim frame design. Because aluminium is strong, the frames do not need to be as bulky as some other materials.

For homeowners, this means more glass and less frame. Rooms feel brighter, views feel clearer and the overall finish looks more modern.

For installers, it gives you a strong selling point when speaking to customers who are focused on appearance.

Ideal for Larger Openings

Aluminium is well-suited to larger door sets and wide glazed areas. This makes it a strong choice for bi-fold doors, sliding patio doors and open plan extensions.

Homeowners increasingly want large openings that connect indoor and outdoor spaces. Aluminium helps make that possible while still offering strength, durability and smooth operation.

Strong and Durable

Aluminium is a robust material that is built to last. It does not warp or swell and is designed to perform well in everyday UK weather conditions.

This gives homeowners confidence in the long-term performance of the product, while helping installers reduce the risk of future issues.

Smooth Operation

Modern aluminium doors are designed to operate smoothly, even on larger systems. This is especially important for sliding doors and bi-folds, where the customer experience depends heavily on how easy the product is to use.

A door that looks good but feels awkward to operate will quickly cause frustration. Aluminium systems are built to provide a premium feel as well as a premium look.

Modern Aesthetics

Aluminium has a clean, sharp appearance that works well on contemporary homes, extensions and garden rooms.

It is also popular with homeowners who want darker frame colours, such as grey or black, because these finishes tend to suit the modern aluminium look particularly well.

The Sheerline system also supports a more consistent appearance across the installation. This is particularly useful on projects where fixed lights, openers and doors all need to look visually balanced.

Strong Thermal Performance

Older aluminium products had a reputation for being less thermally efficient, but modern aluminium windows and doors have moved on significantly.

Today’s aluminium products use advanced thermal technology to help reduce heat loss and improve energy performance. This means installers can offer aluminium while still meeting the expectations of modern homeowners around comfort and efficiency.

Why This Matters for Trade Installers

The launch of Nova’s aluminium range is not just about adding more products. It is about helping trade installers respond to what customers are asking for.

Homeowners are more design aware than ever. Many are researching styles online before they ever speak to an installer. They know they want slim frames, wide openings and a premium finish.

If you can offer aluminium alongside uPVC, you are in a stronger position.

It allows you to quote for a wider range of projects, offer better choices and potentially win higher value work. You are not limited to one type of product or one type of customer.

It also helps you present yourself as a more complete installer. Rather than saying “we only offer uPVC”, you can guide customers through their options and recommend the right product for the job.

That kind of advice builds trust.

Why Nova Has Introduced Aluminium

Nova has always focused on supporting the trade with reliable products, honest advice and straightforward service.

The aluminium range is the next step in that journey.

We are not moving away from uPVC. We are expanding our offering so our trade customers have more options when quoting and winning work.

Many installers already trust Nova for their uPVC windows and doors. By adding aluminium, we can help those same installers take on a wider range of projects without having to build a relationship with a completely new supplier.

“We’ve always been known for supporting trade installers with reliable uPVC products, but the market is changing. More customers are asking for aluminium because they want slimmer frames, larger openings and a more modern finish. By choosing Sheerline, we can offer installers a premium aluminium system that looks great, performs well and is designed with the trade in mind.”

Scott, Director at Nova Trade Frames

That means familiar service, familiar support and a wider product range.

The Benefit of Working With Nova

When you work with Nova, you are not just ordering a product. You are working with a supplier that understands the trade.

We know that timing matters. We know that communication matters. We know that when something arrives wrong or late, it reflects on you as the installer.

That is why our approach stays the same across both uPVC and aluminium.

You can expect made-to-measure products, practical support, clear communication and a team that understands what installers need to keep projects moving.

The new aluminium range gives trade customers another option, while keeping the same Nova service they already know.

Why Trade Installers Should Apply for a Trade Account

If you are not already set up with Nova, applying for a trade account is a simple way to access our full product range and support.

A trade account gives you a more direct relationship with the team, making it easier to request quotes, discuss upcoming projects and get advice when you need it.

It also means you can start offering both uPVC and aluminium options to your customers, giving you more flexibility when quoting for different types of work.

Whether you are a sole installer, builder, developer or growing installation business, having the right supplier behind you can make a real difference.

Final Thoughts

The launch of Nova’s aluminium windows and doors range is an important step forward.

uPVC remains a strong and reliable choice for many projects, but aluminium gives trade installers another option for customers who want something more modern, premium and design led.

With slim sightlines, strong durability, smooth operation, advanced thermal performance and installer-friendly Sheerline profiles, aluminium is becoming an increasingly important part of the window and door market.

For installers, this is an opportunity to expand what you offer, win different types of projects and give customers more choice.

Nova is here to support that.

If you would like to find out more about the new aluminium range, request a quote or open a trade account, get in touch with the team today.

That is why more installers are now looking for a window supplier for installers that offers more than just products.

At Nova Trade Frames, we have always taken that approach. Supporting our customers has been part of how we work from day one. Now, we are taking that one step further with the introduction of our Trade Partner Scheme.

Whether you mainly install uPVC, aluminium, or a mix of both, the aim is the same: to give you reliable products, practical support and a supplier relationship that helps you move forward.

Why Installers Need More Than Just a Supplier

Being an installer today is not just about fitting windows and doors. You are running a business, managing jobs, and dealing with customers who expect a high standard from start to finish.

We regularly speak to installers who are:

• Unsure how to price certain jobs competitively
• Dealing with unusual or complex installations
• Losing time chasing answers from suppliers
• Trying to grow but not sure what the next step looks like

A standard supplier does not help with any of this. They supply the product and leave you to figure the rest out.

That is where having the right support makes a real difference.

“We have worked with installers at every stage, from one-man bands to established teams. The challenges are always similar, it is just the scale that changes.”
— Scott, Director at Nova Trade Frames

What a Good Window Supplier for Installers Should Offer

A good window supplier for installers should make your life easier, not more complicated.

That means:

• Clear, honest communication
• Reliable lead times you can plan around
• Products that are made to measure and ready to fit
• Support when you need advice or help

But more importantly, it means having a supplier that understands how your business works.

You should not feel like you are chasing updates or guessing your way through a job. You should feel confident that your supplier has your back.

Introducing the Nova Trade Partner Scheme

At Nova, we have always supported our trade customers beyond simply supplying products. Whether that is helping with specifications, offering advice, or solving problems quickly, it has always been part of our service.

The Trade Partner Scheme is not a complete change in direction. It is a way of formalising what we already do and making it clearer to our customers.

It is built around one simple idea. If our customers grow, we grow with them.

What This Means for Installers

Becoming part of the Trade Partner Scheme gives you access to support that goes beyond the standard supplier relationship.

This includes:

• Direct technical support from experienced people who understand the job
• On-site engineer support when you need help with surveys, troubleshooting, or installation
• Help with quotes and pricing so you can go back to your customer with confidence
• Practical guidance on installation and manufacturing to help you get it right first time
• Ongoing business support to help you grow
• Leads and referrals where possible
• Consistent, UK manufactured products with reliable lead times
• Manufacturer-backed warranties for added peace of mind

All of this is designed to make your day-to-day work easier and help you build a stronger business.

Real World Support That Makes a Difference

This kind of support is not just a list of features. It has a real impact on how jobs run.

We have worked with installers who were unsure how to price larger jobs. With a bit of guidance, they were able to put together more competitive quotes and win work they might have previously missed.

In other cases, our team has been out on site helping solve installation challenges, saving time and avoiding delays.

For newer installers, having someone to speak to and sense-check decisions can make a big difference in building confidence.

“Sometimes it is not about the product, it is about giving someone the confidence to move forward with a job. A quick conversation can make all the difference.”
— Scott, Director at Nova Trade Frames

Why Installers Choose Nova

There are a lot of suppliers in the market, but what makes the difference is how they work with their customers.

At Nova, we keep things straightforward.

• You deal directly with us, not a call centre
• Problems are dealt with quickly and properly
• We bring over 40 years of industry experience
• We focus on long-term relationships, not short-term transactions

It is not about overcomplicating things. It is about doing a good job, being reliable, and supporting the people we work with.

Built Around Helping You Grow

One of the biggest things we take pride in is seeing our customers grow.

We have worked with installers who started out on their own and have gone on to build strong, established businesses. That growth comes from a combination of hard work, good products, and the right support behind the scenes.

By offering consistent quality, honest advice, and ongoing support, we help you take the next step, whatever that looks like for your business.

Final Thoughts

Choosing the right window supplier for installers is about more than just getting products delivered. It is about finding a company that understands your challenges and supports your goals.

The Trade Partner Scheme is simply an extension of what Nova has always done. Supporting installers, solving problems, and helping businesses move forward.

If your current supplier is just supplying, it might be time to expect more.

Ready to Work with a Supplier That Supports You?

If you are looking for more than just a supplier and want a company that is genuinely behind you, we would love to hear from you.

You can apply for a trade account, request a quote, or learn more about the Nova Trade Partner Scheme to see how we can support your next project.

Even experienced installers can get caught out. It only takes a small mistake to turn into a bigger problem on site. That is why understanding how to properly measure uPVC windows is so important.

In this guide, we will walk through the process step by step, highlight common mistakes, and show you how to avoid them.

Why Accurate Measurements Matter

Accurate measurements are the foundation of a successful install. When windows are made to measure, they are built exactly to the sizes you provide. There is very little room for error.

If a frame is too large, it simply will not fit without making adjustments to the opening. If it is too small, you are left trying to fill gaps, which can affect both the finish and performance.

We have worked with installers who have had to delay jobs because of a simple measuring error. In one case, a window was ordered just slightly too wide, which meant removing additional brickwork before it could be fitted. That added time, cost, and frustration to what should have been a straightforward job.

“Most issues we see with supply only orders come back to measurements. It is always worth double checking before placing the order.”
— Scott, Director at Nova Trade Frames

What You Need Before You Start

Before you begin measuring, make sure you have everything you need:

• A reliable tape measure or laser measure
• Access to both the inside and outside of the opening
• Something to record your measurements
• A clear understanding of whether you are measuring the aperture or the final frame size

Taking a few minutes to prepare properly will help avoid mistakes later.

Step by Step Guide to Measuring uPVC Windows

Measuring correctly is not complicated, but it does require consistency and attention to detail.

Measure the Width

Start by measuring the width of the opening in three places:

• At the top
• In the middle
• At the bottom

Openings are not always perfectly straight, especially in older properties. Using three measurements helps you identify any variation.

Always use the smallest of the three measurements.

Measure the Height

Next, measure the height of the opening in three places:

• On the left side
• In the centre
• On the right side

Again, use the smallest measurement to ensure the window will fit within the opening.

Deduct for Fitting Tolerance

Once you have your final width and height, you need to allow for fitting tolerance.

As a general rule, deduct around 10mm from both the width and height. This gives enough space to position the frame, level it, and apply sealant.

Failing to allow for tolerance is one of the most common causes of tight or difficult installations.

Common Measuring Mistakes to Avoid

Even with experience, it is easy to fall into bad habits. Here are some of the most common mistakes we see when people measure uPVC windows.

Measuring from Plaster Instead of Brick

Always measure from the structural opening, not from internal finishes. Plaster can vary and does not give an accurate representation of the true size.

Assuming the Opening Is Square

Very few openings are perfectly square, especially in older buildings. That is why taking multiple measurements is so important.

Forgetting to Deduct Tolerance

Ordering the exact size of the opening without allowing space for fitting will cause problems. Always factor in the fitting gap.

Not Checking the Depth

Depth is often overlooked, but it matters. Make sure there is enough space for the frame and any additional components such as trims or boards.

Special Considerations for Different Installations

Not every job is the same, and some situations require extra care when measuring.

Replacement Windows

When replacing existing windows, it is important to check the condition of the opening once the old frame is removed. Do not assume everything will be square or consistent.

New Builds

New build openings are usually more consistent, but it is still important to confirm measurements rather than relying on drawings alone.

Older Properties

Older properties can be more challenging. Walls may not be straight, and openings may have shifted over time. Take extra care and allow for additional adjustments where needed.

When to Double Check or Ask for Help

There is no harm in taking a second look or asking for advice. In fact, it can save a lot of time and money.

If you are dealing with:

• An unusual opening
• A bay or shaped window
• Tight tolerances
• A large order where accuracy is critical

It is always worth double checking before confirming the order.

“We are always happy to sense check measurements. A quick call can prevent a lot of hassle later on.”
— Scott, Director at Nova Trade Frames

We provide made to measure products, reliable lead times, and support when you need it, so you can focus on getting the job done.

Final Thoughts

Measuring uPVC windows correctly is one of the most important parts of any installation. It is also one of the easiest areas to get wrong if you rush or make assumptions.

Ready to Order with Confidence?

If you are looking for a supplier that supports you every step of the way, Nova Trade Frames is here to help.

Apply for a trade account, request a quote, or speak to the team about your next project.

On the surface, many suppliers look similar. They all promise quality products, fast delivery, and competitive pricing. But in reality, the differences between them can have a huge impact on your business.

In this guide, we will walk through what to look for in a trade uPVC supplier, the common issues installers face, and how to make sure you are working with a supplier that supports your success.

Why Your Choice of Trade uPVC Supplier Matters

Your supplier is more than just somewhere you place orders. They play a key role in how efficiently your jobs run, how your customers perceive your work, and how profitable each project is.

If your supplier is unreliable, it affects everything. Late deliveries can delay installs, poor quality products can lead to callbacks, and unclear communication can waste valuable time on site.

We regularly speak to installers who have experienced these problems. Many of them only realise how much their supplier was holding them back once they switch.

A good trade uPVC supplier should make your job easier, not harder.

Do They Work Exclusively With the Trade?

This is one of the biggest factors to consider. Many companies claim to offer trade pricing, but also sell directly to homeowners.

This creates a problem. If your customer can go online and find the same product at a similar price, it weakens your position and makes it harder to justify your quote.

A true trade uPVC supplier works exclusively with professionals.

“We have always been clear that we are trade only. Our customers need to know their pricing is protected and they are not competing with us for their own jobs.”
— Scott, Director at Nova Trade Frames

Working with a trade-only supplier gives you confidence that your supplier is supporting your business, not competing with it.

If you are not already set up, it is worth taking a look at how a trade account works and the benefits it can bring to your day to day operations. If you feel like we’re a good fit, you can apply for a uPVC trade account.

Are Their Products Truly Made to Measure?

Every job is different. Accurate measurements and properly manufactured frames are essential for a smooth installation.

Some suppliers rely on standard sizes or lack precision in manufacturing, which can lead to issues on site. Frames that do not fit correctly can result in wasted time, additional labour, and unhappy customers.

A reliable supplier will provide fully made-to-measure products, built exactly to your specifications.

This is especially important when ordering uPVC windows supply only, where you are responsible for measuring and fitting. Having confidence that the product will fit first time makes a huge difference to how efficiently the job runs.

The result is simple. Faster installs, fewer adjustments, and less risk of costly remakes.

Can They Deliver Consistently and On Time?

Timing is critical in the trade. When materials do not arrive when expected, it can delay the entire project and impact other trades on site.

We have worked with installers who have had deliveries pushed back multiple times by previous suppliers. In one case, a small development was delayed because windows were not ready when promised, which caused a knock-on effect across the build.

Consistency is key. A good trade uPVC supplier will provide clear lead times and stick to them.

“Most issues we hear about come down to missed deadlines. We focus on being realistic with lead times and delivering when we say we will.”
— Scott, Director at Nova Trade Frames

When you know your delivery dates are reliable, you can plan your installs with confidence.

Do They Offer the Flexibility You Need?

No two projects are the same. Different properties require different styles, finishes, and specifications.

A strong trade uPVC supplier will offer a wide range of options, allowing you to meet the needs of each customer. This includes:

• A variety of window styles
• A full range of colours and finishes
• Flexible glazing options
• Hardware choices to suit different preferences

Having this flexibility means you can offer more to your customers without needing to source from multiple suppliers.

Whether you are ordering windows or trade uPVC doors, being able to customise your products helps you win more jobs and deliver better results.

Is Their Support Built Around Installers?

Support is often overlooked, but it is one of the most important aspects of working with a supplier.

When you are on site and need an answer quickly, you need a supplier who understands the urgency. Poor communication can lead to delays, confusion, and unnecessary stress.

A good trade uPVC supplier will provide:

• Fast and clear communication
• Help with specifications and ordering
• Advice when you are unsure about measurements or requirements

“If someone is unsure about a spec, we would rather they pick up the phone and ask. A quick conversation can prevent a lot of problems later.”
— Scott, Director at Nova Trade Frames

This level of support gives you confidence when placing orders and helps ensure everything runs smoothly.

Are They Helping You or Holding You Back?

Sometimes the biggest issue is not obvious at first. You might be used to delays, chasing updates, or dealing with inconsistent quality, and assume it is just part of the job.

But it does not have to be that way.

If your supplier is causing regular problems, it is worth asking whether they are helping your business grow or holding it back.

A good supplier should make things simpler. Orders should be straightforward, communication should be clear, and products should arrive ready to install.

If that is not your current experience, it may be time to look at other options.

You can apply for a trade account, request a quote, or speak to the team about your next project.

If you are still working with mixed suppliers or retail-focused companies, this shift is worth paying attention to. Here are seven clear reasons why installers across the UK are making the switch to trade only window and door suppliers like Nova.

1. More Control Over Jobs and Scheduling

One of the biggest frustrations on site is working around someone else’s timeline. When you rely on supply and fit packages or retail suppliers, you often lose control of when products arrive and how quickly issues are resolved.

With a supply only window and door supplier, you control the process. You measure, you order, and you install on your schedule.

Benefit: You plan jobs your way, not around someone else’s availability.
Result: Fewer delays, smoother installs, and better time management.

2. Better Margins on Every Job

Margins matter, especially with rising material and labour costs. When you buy through a supply only model, you remove unnecessary extras and keep control of your pricing.

You are not paying for bundled services you do not need, and you can set your own installation costs based on your experience and workload.

Benefit: Greater flexibility in pricing.
Result: More profit retained on each project.

3. No Competition from Your Own Supplier

This is a big one and often overlooked. Many suppliers advertise trade pricing but also sell directly to homeowners. That creates a situation where your customer can find the same product online and question your quote.

A true supply only window and door supplier works exclusively with the trade.

“We have always been clear on this. We do not sell to the public. Our customers need to know their pricing and their work is protected.”
— Scott, Director at Nova Trade Frames

Benefit: Your supplier supports your business, not competes with it.
Result: Stronger customer relationships and fewer pricing objections.

4. Faster, More Reliable Lead Times

Delays on materials can throw an entire project off track. When windows or doors do not arrive on time, it impacts other trades, pushes deadlines, and creates unnecessary stress.

Supply only suppliers are built around trade demand. That means faster turnaround times and clearer communication.

Benefit: Products arrive when expected.
Result: You stay on schedule and keep projects moving forward.

5. Made to Measure Products That Fit First Time

Every job is different. Off-the-shelf solutions often lead to adjustments on site, wasted time, and sometimes costly rework.

With a dedicated supply-only window and door supplier, everything is made to your exact specification.

We have worked with installers who switched after repeated fitting issues elsewhere. Once they moved to made to measure supply, their install times dropped and callbacks reduced significantly.

Benefit: Accurate products built to your measurements.
Result: Faster installs and fewer problems on site.

6. Better Support When You Need It

Not all suppliers understand the pressures of working on site. When something goes wrong or you need advice, slow responses can cause real problems.

Working with a trade-focused supplier means you are dealing with people who understand your world. They know what matters and respond accordingly.

“We are not just here to take orders. If a customer needs help with a spec or a measurement, we would rather spend five minutes on the phone than see them run into trouble later.”
— Scott, Director at Nova Trade Frames

Benefit: Access to knowledgeable support.
Result: Fewer mistakes and more confidence when ordering.

7. Ability to Offer More to Your Customers

Homeowners expect more choice than ever before. Whether it is colour, style, or glazing options, having flexibility helps you win more work.

A good supply only window and door supplier will offer a wide range of products that can be tailored to each job.

This allows you to present better options to your clients without needing multiple suppliers.

Benefit: Greater product choice and flexibility.
Result: More competitive quotes and higher customer satisfaction.

Final Thoughts

Switching to a supply only window and door supplier is not just a trend. It is a smarter way of working for many trade professionals.

It gives you control, protects your margins, and helps you deliver better results for your customers.

At Nova Trade Frames, we have built our business around supporting installers. We focus on reliability, clear communication, and making sure every order is right first time.

That difference can cost you jobs.

In this blog, we’ll break down why choosing the right trade window supplier matters, the problems installers regularly face, and how working with a trade-focused partner like Nova helps you avoid them.

What Is a Trade Window Supplier?

A true trade window supplier works exclusively with professionals. That means installers, builders, developers, and contractors. They don’t sell directly to homeowners, and they don’t advertise retail pricing.

Everything they do is built around the needs of the trade. That includes faster lead times, made-to-measure products, and support that actually understands how sites operate.

On the other hand, many suppliers sit somewhere in the middle. They promote trade pricing, but they also sell directly to the public. That’s where problems start.

The Problem with Retail-Focused Suppliers

At first, using a supplier that sells to both trade and retail might not seem like an issue. But in reality, it creates a number of challenges that can affect your business.

One of the biggest issues is pricing transparency. If a homeowner can go online, find the same product, and get a similar price to what you’re paying, it becomes much harder to justify your quote.

We’ve seen this happen time and time again.

A Nova customer recently told us about a job where they had quoted for a full window replacement on a residential property. The homeowner decided to “do a bit of research” and found a supplier online offering what looked like the same windows. The price difference created doubt, even though the installer was factoring in labour, experience, and aftercare.

In the end, the installer had to spend extra time explaining the value of their service just to keep the job.

That situation could have been avoided entirely with a true trade window supplier.

“If your customer can go online and see the same product at a similar price, you’re already on the back foot. That’s not how a trade relationship should work.”
— Scott, Director at Nova Trade Frames

Why Trade Installers Should Avoid Retail Suppliers

Working with the wrong supplier does not just affect pricing. It can impact every stage of your job.

Retail-focused suppliers are often not set up to support trade customers properly. That can lead to slower communication, longer lead times, and less flexibility when things need to change.

Another common issue is stock and scheduling. Retail suppliers tend to prioritise volume sales, which can mean delays when you need products delivered to fit a specific install date.

We’ve had installers come to us after experiencing exactly this.

One builder was working on a small development and had ordered windows from a supplier that also sold to the public. The delivery was pushed back twice due to stock issues. This delayed the entire project and affected other trades on site.

By the time they came to Nova, their main priority was simple. They needed reliability.

“Most of our customers come to us after a bad experience somewhere else. It’s usually down to poor communication or missed deadlines. That’s what we focus on getting right.”
— Scott, Director at Nova Trade Frames

The Benefits of Using a Trade Window Supplier

Choosing a dedicated trade window supplier changes how you work for the better. It gives you more control, more confidence, and a smoother process from start to finish.

Protected Pricing

With a trade-only supplier, your pricing is your pricing. Your customers cannot go behind your back and find the same products online. That protects your margins and your relationship with the client.

Faster, More Reliable Lead Times

Trade suppliers understand that timing is critical. Products are manufactured and delivered with installers in mind, not retail demand.

That means fewer delays and better planning for your jobs.

Better Communication

When you call a trade supplier, you are speaking to people who understand what you need. They know the importance of measurements, specifications, and deadlines.

You are not explaining your job to someone who mainly deals with homeowners.

Made-to-Measure as Standard

Every job is different, and a trade window supplier works to your specifications. That reduces issues on site and helps ensure everything fits first time.

Why Installers Choose Nova Trade Frames

At Nova, everything we do is built around being a reliable trade window supplier.

We do not sell to the public. We do not publish retail pricing. Our focus is 100 percent on supporting trade customers.

That means:

• Made-to-measure uPVC windows and doors
• Fast and reliable delivery
• Clear, honest lead times
• Support with specifications and ordering
• A team that understands the pressures of working on site

But more importantly, it means consistency.

We know that when you place an order, you are relying on us to help you deliver a job on time and to a high standard.

“Our customers are putting their name to every install. If we let them down, it reflects on them. That’s why we take reliability seriously.”
— Scott, Director at Nova Trade Frames

Real Results from Choosing the Right Supplier

We’ve worked with installers who have completely changed how they operate simply by switching to a dedicated trade supplier.

One installer we work with regularly had previously been using a mix of suppliers, including some that sold to homeowners. They found themselves constantly chasing updates, dealing with inconsistent quality, and losing time on site.

After moving everything over to Nova, they simplified their process.

They now order all of their windows and doors through one supplier, know exactly what lead times to expect, and spend less time dealing with problems.

For them, the biggest benefit was not just the product. It was the peace of mind.

Final Thoughts

Choosing the right trade window supplier is not just about price. It is about reliability, support, and protecting your business.

A supplier that sells to both trade and retail might seem convenient at first, but it often creates more problems than it solves.

Working with a dedicated trade supplier like Nova means you stay in control. Your pricing is protected, your timelines are clearer, and your installs run more smoothly.

If you are serious about growing your business and delivering consistently high standards, your supplier should be working with you, not against you.

Whether you’re a seasoned installer or managing a multi-property build, this guide walks you through the most common pitfalls and how to avoid them. Getting it right the first time means happier clients, smoother installs, and more profit left in your pocket.

Trade Double Glazed Windows Mistake 1. Incorrect Measurements

Let’s start with the big one. Measurement mistakes are the number one reason why windows don’t fit on the day of install. Common problems include:

• Measuring from the plaster line rather than the brickwork
• Not allowing fitting tolerance (deducting 10mm for adjustment)
• Assuming the opening is square
• Mixing up frame size and aperture size

A window that’s just 5mm too big won’t fit without taking out more brickwork. A window that’s too small will leave large gaps and compromise the fit.

How to avoid it:
Always measure brick-to-brick in three places for both width and height (top, middle, bottom), then use the smallest measurement. Deduct 10mm for fitting tolerance, and clearly specify whether the measurement is the actual frame size or the aperture size. If you’re unsure, double-check with your supplier before ordering.

“We see it time and time again, a great job delayed over 10mm. Taking an extra few minutes on the measurement can save hours later.”
— Scott, Director at Nova Trade Frames

Trade Double Glazed Windows Mistake 2. Confusing Hinge and Opening Directions

It sounds simple, but getting left and right opening directions mixed up is another common issue. The problem usually happens when the spec is written from an internal perspective, while manufacturers work from an external view.

Imagine a window designed to open outwards from the left.

If the order describes that from the inside looking out, you’ll end up with the opposite result.

How to avoid it:
Always specify hinge and handle positions from the outside of the building. Use clear terms like “left-hand opening” or “top-hung”, and include diagrams if needed. When in doubt, send over a sketch or photo to your supplier for confirmation.

Trade Double Glazed Windows Mistake 3. Overlooking Compliance with UK Building Regulations

Installing windows that don’t meet current building standards is a fast way to trigger failed inspections, unhappy clients, or even legal issues. All trade double glazed windows should meet Part L of UK building regulations for thermal efficiency. You may also need to consider:

• Fire escape routes (especially for upstairs windows)
• Safety glass requirements in doors or low-level glazing
• Trickle vents in habitable rooms

How to avoid it:
Make sure your supplier understands the latest regs and supplies frames that meet them as standard. At Nova, all of our uPVC windows are A+ rated and Part L compliant, with options to upgrade to laminated or toughened glass where needed. If you’re unsure, just ask, we’ll walk you through the spec.

Trade Double Glazed Windows Mistake 4. Forgetting Key Glazing and Hardware Details

Window installations are more than just frames. Forgetting about the smaller details can lead to delays, reordering, or disappointment when the product arrives. Common oversights include:

• Not specifying obscure glass for bathrooms
• Forgetting to request trickle vents or restrictors
• Ordering the wrong colour handles or finish
• Overlooking child safety features or fire egress options

How to avoid it:
Create a quick checklist of must-haves for every window order. Include glazing type, handle colour, vent position, safety features, and special requirements like easy-clean hinges or equal sightlines. A good supplier will prompt you for these, but it’s always worth double-checking yourself.

Trade Double Glazed Windows Mistake 5. Using the Wrong Type of Supplier

Not all suppliers are trade-friendly. Some companies offer “trade discounts” but also sell directly to homeowners. This means your clients can shop around, find similar prices, and potentially cut you out of the job.

Worse still, many retail-focused suppliers don’t understand the demands of trade work. Lead times are longer, communication is poor, and you’re often stuck waiting for stock that doesn’t arrive when you need it.

How to avoid it:
Choose a supplier that works exclusively with trade professionals and has a great reputation. At Nova, we’re trade-only, no retail customers, no undercutting, and no DIY quotes.

That means you stay in control of the pricing, the spec, and the schedule.

Trade Double Glazed Windows Mistake 6. Not Asking for Help When You Need It

You might be an experienced installer, but window specs are constantly evolving. Whether it’s a new regulation or a bespoke opening style, guessing can be risky — and expensive.

How to avoid it:
Work with a supplier who will support you, not just sell to you. At Nova, we’re happy to take calls, check drawings, or advise on tricky measurements. You’re not just placing an order, you’re partnering with a team that wants your install to go smoothly.

“We’re not here to tell people how to do their job, just to help them avoid problems we’ve seen before. It’s in everyone’s interest that the job goes right first time.”
— Scott, Director at Nova Trade Frames

Final Thoughts

Ordering trade double glazed windows should be a straightforward process — but the details matter. A small oversight in measurement, glazing, or hardware can turn into a big problem on site.

That’s why working with the right supplier, one who truly understands trade needs, makes all the difference.

At Nova Trade Frames, we specialise in helping installers, builders, and developers get it right. From made-to-measure frames and quick turnaround times to expert support on every order, we’ve built our reputation on being reliable, professional, and trade-first.
