What sets our french casement windows apart in Cranfield.
No Central Mullion
Both sashes meet on a shoot-bolted centre stile that opens with them — the aperture is completely clear when both are open, unlike a standard 2-light casement.
Widest Clear Opening
Up to 1.6m of clear width on a standard aperture — the widest opening on any hinged window we supply, and a compliant Doc B fire escape on habitable first-floor rooms.
Kitchen & Dining Room Favourite
The natural choice above a sink or over a garden view — throw both sides open and the view is uninterrupted.
Available in All Three Ranges
In uPVC, thermally-broken aluminium or heritage flush-casement — same principle, three material finishes to suit the property.
PAS 24 Secured Locking
Multi-point espagnolette locking on both sashes with shoot-bolts top and bottom — as secure as any single-sash casement, tested to PAS 24:2016.
Astragal & Georgian Bar Options
Full bar and glazing options — a French casement can carry the same period detailing as a fixed light of the same size.

- Can I see recent french casement windows work near Cranfield?

- How is a French casement different from a normal 2-light casement?
- A normal 2-light casement has a fixed mullion between the two sashes — you always see the vertical bar. A French casement has no mullion; the two sashes meet on a movable centre stile that opens with them, so when both are open the aperture is completely clear.
- Are they secure without a central mullion?
- Yes — the meeting stile has shoot-bolts at the top and bottom that engage into the outer frame, and the active sash has multi-point espag locking. The whole assembly is tested to PAS 24 and provides the same security as a standard casement.
- Can I have Georgian bars on a French casement?
- Yes — astragal and Georgian bars in 18mm or 25mm, applied or through-frame, are available on both sashes and any fixed lights above. Popular on flush-casement French windows in period properties.
