Opening pattern

Casements hinge outward and can open broadly. Double-hung sashes move vertically within the frame and do not project outdoors.

Clear opening and ventilation

A casement can provide a large clear opening for its frame size. Double-hung ventilation can be adjusted from upper, lower or both sashes.

Clearance and screens

Casements require exterior swing space and usually place the screen inside. Double-hung units keep screens toward the exterior and avoid an outward projection.

Appearance

Casements suit clean vertical lites and contemporary combinations; double-hung profiles align naturally with traditional sash patterns.
