The window frame consists of an outer plastic profile structure, reinforced with steel profile and heat insulated, and an inner structure of wood bar. The wood bar and plastic profile structures of the frame are interconnected with the help of multi-purpose tightening self-tapping screws arranged chequerwise and inserted in the countersunken recesses in the wood bar structure and passing through the plastic and metal profile structures at a 45 angle. ^ EFFECT: enhancement of the structure rigidity and strength (to a degree required); enhancement of sound and thermal insulation and improvement of the indoor microclimate. ^ 3 dwg |
