Inward-opening casement window in Gealan S 9000 Base

The Base is the simplest version of the Gealan S 9000 uPVC window profile: 120 mm frame depth, Uf 1.10 W/m²K, and a sash that slopes away outwards at 15°. That bevel is not decoration but a trick of the light — the shadow on the angled face makes the 119 mm sightline look narrower than it is. Of the S 9000 versions this is the least expensive, and technically it is the equal of the others.

The entry model of the Gealan S 9000 uPVC window, with a bevelled face that makes the frame look slimmer.

A side-hung casement opens only one way — it turns inward on its hinges — and that is exactly why it costs less than a tilt and turn window.

A tilt and turn window has two positions: tilt (a gap at the top, secure enough to leave open overnight) and turn (fully open, also for cleaning). An inward-opening side-hung casement has only the second. That means less hardware and so a lower price, and the window stays just as easy to clean from inside. What you give up is the tilt position: there is no way to set the window to a small gap without it also being able to swing fully open.

The standard size is 1,000 × 1,400 mm, hinged on the left; in the configurator you set the size yourself, and you tell us the hinge side with your quote request. Choose a side-hung casement for a room where you rarely tilt and do value the full airflow when it's open — a store room, a garage, or a window nobody leaves on a night-time gap.
