2-pane window, 1 tilt and turn 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.

Fixed glass on the left for the full view, a tilt and turn sash on the right to ventilate: this window combines both without either losing out.

Of the double windows, this is the most chosen split: one pane stays fixed and keeps the view unbroken, the other is a full tilt and turn window. So you don't have to choose between a large piece of glass and being able to air the room — you get both, in one frame with one mullion. In the configurator you choose whether the tilt and turn pane goes on the left or the right.

The standard size is 1,800 × 1,500 mm, split equally between the two panes. If you need more ventilation than one tilt and turn pane gives, the 2-pane window with two tilt and turn sashes — with a tilt and turn pane on both sides — is the broader choice; if you want no opening at all, the 2-pane fixed window is the simpler one.
