Sleekly styled and thermally efficient bifold doors

Sleek, secure, and expertly fabricated, Evaframe’s Cortizo Bifold and Cortizo Bifold Plus aluminium bifold doors are built for installers and builders who value quality and speed. We manufacture in-house, providing you with fast lead times and a reliable supply across South Wales and South West England. As a result, you can complete projects on time and with confidence.

Performance and Specifications Installers Can Rely On

The Bifold has a 73 mm frame depth, while the Bifold Plus offers a 80 mm frame depth. Both have slim sightlines that maximise glass area and flood interiors with natural light. With double glazing, you can achieve U-values as low as 1.2 W/m²K. Triple glazing improves this to ≥0.8 W/m²K. These systems can span up to 14 sashes and reach heights of 3,000 mm, making them ideal for both residential and large commercial openings.

Additionally, we design them for smooth and trouble-free operation. Hidden rollers, precision hardware, and advanced engineering ensure lasting performance. We test each system for up to 50,000 opening cycles, ensuring it will withstand regular use. Security is also a priority, with both systems meeting rigorous industry standards.
