Glazed back door in K-vision Classic

The K-vision Classic is the flush profile from Kömmerling's K-vision system, updated to a depth of 76 mm — just over 40 mm less than the 120 mm of the Trend and the Cube. Uf 1.10 W/m²K and room for 48 mm glass as standard. It can be fitted with or without a rebate, and glazing bars and a different colour inside and out are possible. That makes it interesting where the reveal is tight, and less so where you want a recessed face.

A flush K-vision (Kommerling) uPVC window, 76 mm deep, for a replacement where the reveal leaves little room.

One door that opens outwards rather than inwards, glazed from top to bottom: a back door that works as a window onto the garden as well.

Where a front door opens inwards, this door opens outwards: the leaf swings over the patio rather than into the room, so it stays out of the way of the kitchen or living room behind it. The door itself is glass, more so than a front door, because the view of the garden is usually the point. If you are looking for a solid or half-glazed back door, note that this layout is a glazed door.

The standard size is 1,000 × 2,100 mm, the same as a single front door but with the opening direction reversed. If you want a wider opening onto the patio, French doors — two of these doors side by side — or a sliding patio door are the layouts made for that.
