Alumina by Liniar


Design

The jewel in the crown of the Alumina range – our bi-folding door system enables a full wall of your home or property to be opened up to the outside.

Ideal for commercial or heavy duty applications, Alumina sliding bi-fold doors offer added strength and security.

Spanning up to 7 panes wide, Alumina bi-folding doors can be supplied with almost any powder coated RAL finish, or foiled with a realistic factory fitted woodgrain foil.

A true aluminium bi-fold system, Alumina doors are available with 28mm double or 36/40mm triple glazing, offering U-values as low as 1.3W/m²K.
