Choose gas strut for open sightlines

A single sash can clear the opening, but it projects outside and needs overhead space, safe reach and weight-matched hardware.

Choose folding for a broad retrofit opening

Folding panels park beside the opening and avoid a deep wall pocket, while the stack consumes side space and adds vertical joints.

Choose sliding for contained movement

Sliding panels stay within the frame and suit tight exterior conditions, but overlapping panels reduce the maximum clear opening.

Choose pocketing during design

Pocketing can clear most of the opening but needs a deep, drained and serviceable wall cavity planned before construction.

Questions about this topic

Which style gives the widest opening?

Pocketing and folding systems can clear much of a span, while a gas-strut sash can clear the full frame area. Exact results depend on supported product geometry.
