Português Glazing units
A suitable glazing unit can be selected for each window model. The units in our leading offer include three panes, 2 warm spacer and 2 low-emission coats. In each glazing unit, the external pane is toughened. Selected models are equipped with a glass with a self-cleaning coating or a laminated P2A glass (the safety glass, also called "tamper-resistant" glass).
