We’re excited to announce a major upgrade to our aluminium product range with the launch of our brand-new aluminium systems built using the Cortizo profile. Designed to deliver improved performance, enhanced aesthetics, and an even more installer-friendly experience, this new range represents a significant step forward while maintaining the clean, modern look our customers already know and love.

Best of all, while the technology and design have been upgraded, pricing remains unchanged. This means you can benefit from improved systems and performance without any increase in cost.

In this blog, we’ll take a closer look at the new Cortizo-based systems now available, including aluminium bifold doors, windows, and sliding patio doors.

Why We’ve Upgraded to Cortizo

Cortizo is one of the leading aluminium system manufacturers in Europe, known for producing high-performance profiles that combine durability, efficiency, and contemporary design. By introducing this new range, we’re able to offer products that deliver:

• Improved thermal performance
• Slimmer, more modern sightlines
• Enhanced aesthetics
• Simpler and faster installation

For installers and homeowners alike, the new systems offer the perfect balance of performance, reliability, and visual appeal.

Aluminium Bifold, French & Single Doors

All our aluminium products will now be made using the Cortizo bifold system, and we’re proud to be the first to launch this system in the UK. Some of the benefits include:

Slimmer Sightlines

The new system features 100mm sightlines, reduced from the previous 107mm design. While this may seem like a small change, slimmer sightlines make a noticeable difference to the overall look of the doors.

The result is a cleaner, more modern aesthetic that allows for larger glass areas and better natural light.

Installer-Friendly Design

Another key improvement is the return of the customer-favourite pre-gasketed clip-in bead. This design makes installation simpler and faster while maintaining the same familiar look that installers and customers are already comfortable with.

By combining improved performance with a familiar installation process, the new bifold system offers a smooth transition for installers while delivering better results for homeowners.

The Same Look You Know and Love

While the technology behind the system has been upgraded, the overall appearance remains very similar to previous designs. This means customers can enjoy the same stylish aluminium bifold doors, now with enhanced performance and refined detailing.

Aluminium Windows

Alongside our new door systems, we’re also introducing a refreshed aluminium window range built using Cortizo profile. These windows are designed to offer flexibility, performance, and design versatility, making them suitable for a wide range of projects.

Multiple Frame Options

Our aluminium windows are available in Flush, Standard, and Heritage frame options, allowing you to choose the right style for your property.

• Flush frames offer a sleek and contemporary look that’s ideal for modern homes and new builds.
• Standard frames provide a classic aluminium window style suitable for many different property types.
• Heritage frames are perfect for character properties, period renovations, or projects that require a more traditional appearance.

This variety ensures the windows can complement everything from modern architectural designs to traditional restoration projects.

Excellent Energy Efficiency

When paired with energy-efficient glazing, the new aluminium windows can achieve U-values as low as 1.0 W/(m²K). This high level of thermal performance helps reduce heat loss, improve indoor comfort, and support energy-efficient home design.

As energy efficiency continues to become a priority for homeowners and developers, high-performance aluminium windows are an increasingly attractive option.

Aluminium Sliding Patio Doors

Our sliding patio system is made using the Cortizo 4900 system and is another key addition to our upgraded aluminium range. Sliding patio doors remain one of the most popular choices for connecting indoor spaces with gardens, patios, or terraces. The Cortizo 4900 system has been designed to deliver a modern aesthetic while remaining practical and easy to install. Benefits include:

Ultra-Slim Interlocks

One of the standout features of the system is its slim 35mm interlocks. These slim profiles maximise the visible glass area, allowing more natural light into the home and providing clearer outdoor views.

Slim interlocks also enhance the overall look of the doors, creating a minimal and contemporary appearance that works particularly well in modern homes and extensions.

Fully Beaded Design

The system features a fully beaded design, helping to make installations faster and cleaner. For installers, this simplifies the process while maintaining a secure and high-quality finish.

Strong Thermal Performance

When combined with energy-efficient glazing, the Cortizo 4900 sliding patio doors can achieve U-values of 1.2 W/(m²K). This helps improve the overall energy efficiency of the property while maintaining the large glazed areas that make sliding doors so desirable.

Continued Support for Existing Systems

Our goal is to offer flexibility while expanding our aluminium offering with the latest innovations. While we’re excited to introduce this new Cortizo range, we understand that some projects may still require alternative systems, if that is the case, please contact us so we can still provide quotes where possible.

What Stays the Same?

Although our aluminium systems have been upgraded, many of our most popular products remain unchanged.

Our ranges of:

• Rooflights
• Roof lanterns
• uPVC products

continue to perform exactly as before and remain just as popular with customers and installers. This means you can continue specifying the products you trust while benefiting from the improvements introduced to our aluminium systems.

Looking Ahead

The launch of our new Cortizo-based aluminium range marks an exciting milestone for us. With improved performance, slimmer sightlines, and more installer-friendly designs, these systems represent the next generation of aluminium doors and windows.

And this is just the beginning.

We’re already working on more exciting developments planned for 2026, with further innovations designed to enhance performance, aesthetics, and installation efficiency across our product range.

At QUAD, we’re proud to introduce our new Cortizo aluminium system range, bringing you improved performance, slimmer sightlines, and a more installer-friendly design while maintaining the same great pricing. Whether you’re specifying bifold doors, aluminium windows, or sliding patio systems, this new range delivers the performance and aesthetics modern projects demand.
