SUNFLEX SF75 TRIPLED GLAZED BI-FOLDING SYSTEM

SUNFLEX BI-FOLDING DOOR

AWARD WINNING ALUMINIUM BI-FOLDING DOOR SYSTEM

TRIPLE GLAZED BI-FOLDING DOOR

Elevate your home with the Sunflex SF75 aluminium bifold doors, a high-performance glazing solution that combines minimal sightlines and architectural elegance with class-leading thermal and weather resistance.

Made from precision-engineered thermally broken aluminium, the SF75 frames have a slender 75 mm depth and offer an ultra-clean aesthetic. With sightlines as fine as 115 mm, these bifold doors flood rooms with natural light and provide seamless indoor-outdoor integration—perfect for modern extensions, open-plan living spaces, or contemporary renovations.

 

The SF75 system is optimised for energy efficiency. Its patented 44 mm multi-chamber thermal break is tailored to accommodate high-performance triple glazing, enabling U-values as low as 0.8 W/m²K. This thermal performance places it firmly in the territory of Passivhaus-standard bifold doors, making it one of the most thermally efficient options available in the UK.
