Sunflex SF55 & SF75 Aluminium Bifolding Doors

The Sunflex SF55 & SF75 range is one of the slimmest stacking bifolding door system on the market, offering an impressive 95% clear opening. With a total of 12 panels in each direction it is possible to create spans of up to 25m with heights of up to 3.5m.

Together with the flush track option, a virtually seemless transition between inside and outside is experienced.

Sunflex bifolding doors offer versatile configurations including bays, segmented radius curves and fixed or moveable 90 or 135 degree corner posts to create the effect of infinity.

The Sunflex SF55 is an award winning ultra slimline bifolding door system offering minimal stacking, vast panel sizes and unrivalled weather ratings. The Sunflex SF75 is the most thermally efficient system on the market achieving an overall U-value of just 0.9W/m²K.

Uniquely, the Sunflex SF55 and SF75 are available with a timber clad option. The SF55C & SF75C offers the best of both worlds, allowing you to enjoy the beauty and warmth of timber internally whilst benefiting from the maintenance-free aluminium externally.
