Sheerline Double Doorsets


Alumina by Liniar:

a true aluminium door system

Alumina offers the first concept in aluminium doors, breaking new ground with
superb strength, high security, low U-values, sculptured lines and a ‘warm touch’ exterior.

Our system allows you to create a foiled aluminium system that matches our pvc suite. Suitable to couple to pvc windows, screens or doors using our normal profile sections, installation is simple and efficient.

Designed and developed by the same team of experts as our window system, the Alumina door range offers superb thermal performance and a host of other features to appeal to the discerning consumer.

Ideal for the home, commercial and heavy duty applications
