French doors 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.

Two doors that open outwards from where they meet: together they give a wide opening with no fixed centre section in the way.

Where the back door layout has one door opening outwards, French doors put a second one beside it. Both doors open outwards from the middle, so the whole width can be cleared — unlike a sliding patio door or a bifold door, where part of the glass always stays in front of the opening or folds against the side. It does need room outside for two doors to swing open.

The standard size is 1,600 × 2,200 mm. That is narrower than a sliding patio door or a bifold door, but with no tracks or folding hardware — a simpler and often cheaper way to get a wide opening onto the garden if you don't need the full width of a sliding patio door.
