A casement window is hinged on one vertical side and swings outward like a door. You open it with a crank or a push handle. Fully open, a casement catches side breezes a sliding window can’t — the sash acts like a sail.
Why we sell more casements than any other operable
- Tightest seal of any operable window (hardware pulls the sash against a compression gasket)
- Full sash clears the opening when open — maximum airflow
- Clean, minimalist look with no sill lip or rail divide
- Egress-compliant for bedrooms at the right sizing
Build
- 14-gauge welded steel sash and frame
- 2-1/4″ frame profile, 1-3/8″ sash
- Insulated low-E dual-pane glass, argon-filled
- Maco or Roto hardware with lifetime mechanical warranty
- Stainless steel friction hinges rated for continuous Gulf-coast humidity
Standard sizes
- Single casement: 24″ × 48″ up to 36″ × 72″
- Paired casement (French-style): 48″ × 60″ up to 72″ × 72″
- Custom sizes to structural limits
Screens
Roll-down interior screens are standard (since the sash swings out). Optional motorized screens on larger units.
Where they fit
Kitchens (crank opens easily over a sink), bedrooms (egress), bathrooms, and any spot where maximum airflow matters.
