The three-pane Passive 90 profile is perfectly suited for installation in buildings constructed in accordance with passive construction requirements, thanks to its high thermal insulation.
The wood from which our windows are made is very carefully selected. The lumber we use for our products is carefully dried and the wood itself is free from all anatomical defects such as knots, curls or twists of fibres.
In production of our windows we use four types of wood: pine, oak, larch and meranti. Depending on the profile of the window, the wood is glued 3 layers – for 68 mm section on the thickness or 4 layers – for 78 mm and 90 mm section, and also glued on the length with micro-ties. It is possible to make a window with a solid outer layer up to a height/length of 3m. Over 3m of lumber is glued on the length with microclips.
