- 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.
