MB-SR50 IW is a curtain wall system with an inward opening window and an invisible external frame.
A variety of opening elements is available in such a façade (outwards opening windows - MB-SR50 RT or inwards). Additionally, it is possible to install windows with a visible frame, “frameless” from the MB-SG50 system, or hinged outwards.
ALUPROF has introduced a construction allowing the window to open inwards, whereas in the external view no difference between the fixed glazing units exists. From the internal side, we obtain the effect of flush transoms and mullions. The window is structurally glazed with the glass pane glued without the so-called “stepping”.
A definite advantage of MB-SR50 IW lies in its high thermal insulation. The Uf coefficient for the standard version amounts to 1.82 W/m2K.
