Best for

Maximum ventilation from a given opening — the best airflow of the four.

Watch out

Cannot be left open in rain, and a full sash needs robust hinges in a coastal or humid location.

Cost effect

Moderate.

Scope effect

Needs swing clearance inside or out, and coordination with any security screen.

Best for

Rain-prone elevations — it can stay open in a shower, which matters here.

Watch out

Restricts the clear opening, so it ventilates less than a casement of the same size.

Cost effect

Moderate.

Scope effect

Projects outward; check it does not foul walkways, grilles or an adjacent opening.

Responsible

Best for

Wide openings where a swinging sash has nowhere to go.

Watch out

Only half the opening ever ventilates, and the bottom track collects dirt and needs regular clearing.

Cost effect

Moderate; large spans cost more.

Scope effect

Track drainage must be resolved — a blocked track is a leak path in heavy rain.
