Available Combinations

Side by side

Side by side on a horizontal plane. Available with a 100mm, 50mm or 18mm gap and all flashing kits. Great for buildings with a slim roof.

Over & Under

One over the other on a vertical plane. The roof windows situated in a vertical column can be different lengths but must be the same width.

100mm gap only

Grid System

Grid Systems are simply extensions of a Quad-Lite system. Unlike the Quad-Lite system, the distance between all roof windows whether on a horizontal or vertical plane must always be 100mm.

Quad-Lites

Quad-Lites are simply an amalgamation of the Combi and Bi-Lite systems. Identical to the Bi-Lite system, the lengths of the roof windows can vary in a vertical column but not in a horizontal row.

Dormer System

The Keylite Dormer System opens up the opportunity for a unique fresh air experience with the convenience of the top handle on our Centre Pivot Windows, allowing easy opening to create a well ventilated and bright space.

Combi Ridge

Combi Ridge roof windows may be installed along the roof ridge to maximise light and space at the highest point of the pitched ceiling and create a striking feature.

Dormer Apex System

The Keylite Dormer System creates a well ventilated and bright space.
