Why Choose Alumina

 

Excellent energy efficiency, a beautiful warm touch foil finish or RAL coating and stunning, vast expanses of glass are only a few of the reasons why customers choose Alumina bi-folding doors by Liniar.

From character properties to modern new builds, the Alumina bi-folding door is an ideal solution. With hundreds of wood grain and plain colour foil finishes available and over 150 RAL colours, Alumina bi-folding doors match perfectly with Liniar uPVC windows and doors. For homes and businesses that need traditional looking timber appearances, the realistic wood grain foil finishes are the perfect solution. A low maintenance alternative to timber, Alumina bi-folding doors are easy to clean and don’t require annual care or staining.
