ALI VU Profile

The ALI VU series offers a range of high quality glazing solutions for side and top hung open out windows suitable for both the residential and commercial markets.

Ali VU is a super slimline aluminium window with a polyamide thermal break giving impressive thermal efficiency. Available with a host of design options, Ali VU’s strong super slim frame has a depth of just 38mm (fixed light) or 66mm with standard vent and is available in sizes up to a maximum of 1400mm x 1400mm, to give the widest views and maximise daylight in every room.

Ali VU is ideal for both domestic and large scale residential projects and is perfectly complemented by our Ali FOLD door range. The stepped face option also means that Ali VU is perfect as a modern, energy efficient replacement for heritage style steel windows in both commercial and residential buildings.
