High-performance glazing

Our bespoke window system is thermally broken and provides strength and high-performance in a fixed, opening or top hung configuration. We use extruded 6063 aluminium alloy sections heat treated to T4 temper, which complies with the BS1474 standard.

Your choice of configuration

As the name suggests, our bespoke windows can be manufactured and configured to your exact specifications, allowing you to create unique glazing features in your property.

You can choose from fixed or opening windows, depending on your required functionality for the window. For our range of opening windows, fittings include an adjustable friction hinge with in-built 15-degree restrictor stay and reverse position catch. This allows the window to be turned 180-degrees, enabling both sides of the window to be easily accessed for cleaning from inside the home.
