Transformative Bifold Doors
Bifolding doors made with the ALUNA 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.
Engineering-grade hardware allows for silky smooth opening and closing operation. Perfect to open up your space to the outdoors and create a visually stunning addition to your property.
As an enhancement on the known and loved BF73 bifold system, the super slim profile sections of the ALUNA 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 ALUNA bifold system also has part L compliant U-values as low as 1.1 W/m2K, DER Rating B, when combined with triple-glazed glass, and is secure to PAS24.

New to the ALUNA bifold range is our 90 degree door restrictor. This prevents the door from opening more than 90 degrees, if it was to get caught in the wind.
