Strength With Size

Commercial and heavy-duty applications require greater strength, with wider and taller panes of glass and bigger spans. Alumina by Liniar is a true aluminium door, manufactured with standard aluminium machinery, with panes spanning up to 1.2 metres wide and 2.5 metres high.

Perfectly Matching

As well as being available in practically any powder-coated colour imaginable,

what makes Alumina unique is that it's also available in a beautiful woodgrain or flat foiled finish, enabling consumers to choose a style that perfectly matches the windows of their property for a perfect finish.
