For over 20 years SUNFLEX UK has been renowned for the manufacturer of superior quality glazing systems, including award-winning German designed bifold doors.
With the changes to Building Regulations that came into force in June, the focus on thermal efficiency of glazing systems for new-build homes, extensions and renovations has never been greater.
The challenge for self-builders has been finding the balance between performance, thermal efficiency and aesthetic appeal when it comes to glazed doors, but the SUNFLEX SF75eco aluminium bifold door system does just that.
Advanced thermal performance
With a patented 44mm multi-chamber thermal break, the SF75eco is specifically designed to accommodate a triple glazed unit. The result of this advanced engineering is that no aluminium bifold door system on the market can achieve lower U-values that the 0.8W/m²K that the SF75eco is capable of – making the doors suitable even for Passivhaus standard builds.

Advanced weather performance
With double rebated seals, innovative track detail and advanced gasket technology the SF75eco is capable of achieving some of the most advanced weather protection performance of any bifold door on the market – perfect for coastal or remote locations or ideal for urban eco-homes. Learn more
Widest range of configurations
Whether you require a 3-panel set of bifold doors for your extension, or a 22-panel set to open up the entire side of a venue, the SF75eco achieve it. With panels up to 3000mm tall and up to 1200mm wide, the system offers the widest choice of configurations of any bifold door on the market and can even be used to create completely open corner designs or even curved sets of doors.

Slender aluminium frames
The challenge for architects has been incorporating glazed doors that don’t just perform well, they also actually look good in the finished design as well and the SF75eco achieves that. With slender 117mm sightlines and panels up to 1.2m wide and 3.6m high the doors maximise the glass area when closed and provide a seamless connection between inside and out when open. Learn more
