The ultimate in aluminium door design, Alumina bi-folding doors have been crafted to the highest standards, combining high levels of energy efficiency with the superb strength of aluminium. Able to span up to 7 panes wide, 8.5m overall, with sash height up to 2.5m high.
Liniar has applied its design and development expertise to create an innovative aluminium door system - Alumina. The fully aluminium 70mm bi-folding door offers even greater spans and heights than its uPVC sisters, thanks to superb strength and stability.
This means Alumina is ideal for larger apertures, and since it's been crafted for perfect consistency in style and colour, products from both our aluminium and uPVC ranges can be coordinated seamlessly.
With aluminium doors, heat is often lost through the lock – however Liniar’s clever polyamide thermal locking system prevents this, allowing Alumina bi-folds to achieve U-values
as low as 1.2 with triple glazing to keep your home warm and cosy. In addition to powder-coated finishes, Alumina doors can be foiled with flat coloured or woodgrain effect, giving the exterior a warm touch.
