The initial material for production of our windows is pine timber, oak, shorea of 12% humidity. Four-layer plywood with separated knots, glued with waterproof glues, is made of timber. Then, window elements are made of plywood, in a machining centre and other specialist machine tools. After gluing rails the next operation is immersed proofing in impregnants (of ADLER company).
Dried up elements are filled with wood fillers and ground before applying lacquer (of ADLER company using a method of airless spraying).
The next stage is fitting with hardware of ROTO company. In the last station there is installing an aluminium profile, which aims to drain of water, place gaskets, stick self-adhesive gaskets under a window pane, place a heat-insulating window pane, screw down window boards as well as force in silicone between wooden elements and a window pane in order to seal perfectly.
