SUNFLEX aluminium bifold doors lead the way in innovation and design, setting the standards for other companies to follow. Rather than emphasising on only one or two elements that make the SUNFLEX doors stand out, there are countless features that make the SF55 and SF75 head and shoulders above the rest. German design and manufacture, slim sight lines, contemporary, square edged profiles throughout and colour matched furniture in line with the frame make SUNFLEX doors the best looking on the market. Choose between our award-winning SF55 and SF75 - the only German made system with a BSI Kitemark certificate - the perfect combination.

Aluminium is an ideal material as it’s light, strong and stable with slim profile sections to minimise the visible framework and maximise the glass area. Gain reassurance in the most exposed locations with this virtually maintenance free material.
