Sliding vs Casement Windows
Sliding windows save space and suit wide openings and balconies. Casement windows open fully, give the most air and seal tightest against dust and noise. Many homes use both.

Where each works best
- Sliding: balconies, wide openings, rooms where a swinging sash would hit grills or furniture.
- Casement: bedrooms on noisy roads, kitchens and bathrooms where you want maximum air.
- Combination windows: a fixed glass with a casement or sliding part, for wide openings.
Frequently asked questions
Which is more soundproof, sliding or casement?
Casement windows, because their gaskets press tightly shut when locked. Sliding windows with laminated glass are also quiet.
