Casement windows explained
Types of casement window
A casement window is hinged at the side or top and opens outwards like a door. Within that, there are several types: storm casements, where the sash overlaps the frame; flush casements, where the sash sits level with the frame for a cleaner, traditional look; top-hung and side-hung openers; and fixed panes combined with openers in the same frame.

uPVC and aluminium casement windows
uPVC casement windows are the most popular replacement style across the UK because they are good value, low maintenance and available in many colours. Aluminium casements use a slimmer frame, which suits modern homes and larger casement windows where you want more glass. Both are fitted with A-rated glazing as standard.

Handles and locks
Casement windows use a handle that operates a multi-point locking mechanism, engaging the sash at several points around the frame. Handles come in different finishes and styles, and some openers can be fitted with key locks or restrictors. Worn handles and hinges are a common reason casements stop closing properly, and they can often be replaced without a new window.

Casement windows across the UK and the South West
Casement windows are the standard window style on most UK houses built in the last century, which is why they are the usual like-for-like replacement. In the South West the choice often comes down to exposure and appearance: a plain storm casement for a modern estate home, or a flush profile in a heritage colour for an older cottage. We bring samples to the free survey so you can compare them on your own house.
Casement windows replacement
Replacing casement windows usually means removing each old frame and fitting the new one into the same opening, one window at a time. If your existing casements are sound but the colour has faded or no longer suits the house, on-site spraying is an alternative to replacement.

More questions
What is the difference between casement and sash windows?
Casement windows are hinged and open outwards; sash windows slide up and down. Casements are the most common replacement style, while sash-style windows suit houses that originally had sashes.
Can casement windows be made large?
Yes. Larger openings can combine fixed panes with openers, and aluminium casements carry large panes on a slimmer frame.
