Weatherproof on the outside, flexible material on the inside. This combines the benefits of a PVC or timber window with those of an outer aluminium shell. If a further glass pane is integrated in the aluminium front profile, this creates a cavity between the front profile and the glazed window. Interior blinds can easily be integrated here. Thanks to its extremely corrosion-resistant TRICOAT-PLUS coating, the composite strap is the perfect match for the front panel in terms of resistance to weathering.
