Casement Windows

A dependable window for any elevation

Casement windows remain the UK's most popular window style for good reason — reinforced multi-chambered uPVC frames, a choice of opening configurations, and glazing options to suit any budget. Every casement window we install is surveyed, manufactured and fitted by our own teams, with a 10-year guarantee on frames and glazing.

Shootbolt locking as standard

Every casement window locks at a minimum of two points via a concealed shootbolt mechanism, tested to PAS 24. Handles are available in white, chrome, satin or black to match your interior.

Ventilation

Trickle vents and night-vent catches

Fully reversible casements tilt in for cleaning from the inside, while a discreet night-vent catch lets you ventilate securely overnight. Integrated trickle vents keep background airflow moving without opening the window at all.

A stormproof casement has a sash that sits proud of the outer frame for better weather resistance — this is what we fit as standard. If you'd prefer a sash that sits flush with the frame for a more traditional timber look, see our Flush Sash Windows range.
