The 2-pane configuration can be manufactured up to 5.8 metres wide and 3.0 metres high, while supporting a maximum sash weight of 300 kg.

Featuring an overall outer frame depth of 142 mm with two 62 mm deep sashes, the system is well suited for contemporary straight-through openings. Despite the substantial weight of the door panels, smooth and effortless movement is achieved through high-capacity tandem rollers.

The system also incorporates a robust aluminium threshold and a comfortable gripping D-handle, securely anchored into the concealed steel reinforcement within the sash. These features combine strength, durability, and ease of operation for large patio door applications.

An acoustic laminated inner pane inside a double-glazed unit, with the two panes at different thicknesses and a wide cavity. Just as important, choose a casement or tilt-and-turn window rather than a slider, because the sash needs to compress onto its gaskets to seal.

Yes. We bend profile on a heated forming table from a site template, so semi-circular, segmental and elliptical heads are all possible, fixed or with an operable lower sash.
