As an enhancement on the known and loved BF73 bifold system, the super slim profile sections of the bifold system minimise the visible framework and maximise the glass area, with sightlines of just 107 mm from frame to sash.

Offering one of the largest sash sizes available, up to 1200mm wide and 3000mm high per pane, the bifold system also has part L compliant U-values as low as 1.4 W/m2K, DER Rating B, when combined with highly energy efficient glass, and is secure to PAS24.

Bifolding doors made with the bifold system can be manufactured with up to 7 leaves each way (14 in total), opening from the left or right, towards the inside or outside of the property.

The moving corner post option enables right angled bifolding doors, including the return, to open out fully*, with the option of a fixed corner. *Structural support needs to be in place.
