Aluminium Residential Casement Windows

Residential Casement Windows

Choose from top, side and bottom-hung designs from our range for this classic style of window, for which we offer a great selection of hardware so you can make your windows your own in terms of security, functionality and ability to withstand the weather.

Equally, to suit a variety of settings, you can choose from inward or outward opening models. These might include residential environments like social housing, new builds or refurbs, conservatory walls, light commercial environments or low, medium and high-rise buildings. The beauty of these windows is they also suit listed and period structures, including those in conservation areas.

Better by design

There are options for internal or external, and double or triple glazing, as well as a French window model.

Frame depth can be 58mm or 70mm, while the flat, chamfered or sculptured detailing gives you the choice of a classic or modern look.

Trickle ventilation is made easy thanks to the integrated deep head profiles, while thermal performance is enhanced by the unique polyamide thermal break design.

The dual and single colour options available include metallic finishes, and 24-44mm DGUs are fitted for enhanced acoustic and thermal performance.
