Glazed back door in Aluprof MB-Ferroline

The Aluprof MB-Ferroline is made to look like steel pivot doors and old factory windows: 97 mm of sightline for frame and sash together, in aluminium. At 97 mm it has the slimmest combined frame-and-sash sightline of the Aluprof windows; only the Reynaers CS 77 (89 mm) goes below it in aluminium — for comparison, the Gealan S 9000 in uPVC sits at 119 mm. That slimness costs insulation: Uf 1.50 W/m²K, against 0.57 for the MB-86N. The 110 mm frame depth is there for stiffness, not for insulation.

Steel-look aluminium windows: a 97 mm sightline, the slimmest of the Aluprof windows.

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.
