ECO Bi-Fold Door

Redefining performance and durability in industrial materials

As an enhancement on the known and loved BF73 bi-fold 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 1200 mm wide and 3000 mm high per pane, the ALUNA 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.
