System description
The main characteristic feature is connection between wood and aluminium profiles with 24 mm thermal break. Thickness of construction for frames and sashes increased to 70-93 mm, what improves the thermal insulation of system.
Various constructions can be made in this system: double sashes windows, tilt and turn windows, side hung casement windows. The PW 93 Wood uses wood straps from tropical wood of good quality. It is resistant to weather conditions and presents in a aesthetic way.
