Choose from three track options

The SF55e is available with the choice of three track options, non-weathered flush track, low-threshold track and weathered track- providing a perfect solution for any location. For sheltered locations the flush track offers a consistent floor level between inside and out, the low-threshold track offers a DDA compliant track for less sheltered locations and the double rebated weathered track offers the ultimate in protection from the elements.

Contemporary appearance

With contemporary square edge profile and sightlines of just llSmm the SF55e does not just perform perfectly, it looks great as well. The slim frame allows larger glass units to be used, maximising the amount of light that enters your home and enhancing the views out. The narrow frame of each panel measures only SSmm from front to back minimising the stacking area when opened.

Infinite colour options

Choose from Silver Anodised or one of four polyester powder coated standard colours (Anthracite Grey RAL 7016, White RAL 9016, Aluminium RAL 9006 and Grey RAL 9007) or choose from more than 200 RAL classic colours or specialist finishes including textured paint, anodised or wood grain effect to perfectly complement your home. We can even dual colour your doors so that internal and external faces of the frame are different colours.

Weather and thermal performance

The SF55e is available with a double rebated top and bottom tracks and incorporates a multi-chambered EPDM gasket interlocking in to the panels to protect from wind and rain. For thermal performance the SF SSe achieves overall U-values of just 1.3W /m2K when triple glazed (utilising a sealed unit with a U-value or 0. 7W /m2K) and just 1.6W /m2K when double glazed (utilising a sealed unit with aU-value or 1.0W/m2K).

Wide range of configuration options

The SF55e is perfect for almost any type of extension, renovation or self-build project with each individual panel measuring up to 1.2m wide and up to 3m high for narrower panels. The system can open inwards or out, be utilised as a single door or French door and as bi-fold doors with a huge number of configurations from a 2-panel set replacing double doors, up to a 22-panel set that opens up the complete side of a building.
