the frame available for inserting accessories is of 24 mm with a margin of +1/-0 mm.
- The shutting system is of "open connection" type, the gaskets of the external parameter of the frame will fit into
a specific appendage of the shutter profile
1.2 Termical insulation.
the thermic cut profiles must be composed of 2 aluminum semi-profiles, external and internal one, connected by isolating bares made of strengthened polyamide 14,6 mm high. The coefficient of thermic conductance (Kr) measured according to the DIN 52619 section 3 set of regulations will be included in the 2.2 group according to DIN 4108.
1.4 windowpanes..
the flange profiles must guarantee the perfect fixing of the windowpane in the frame. The internal and external
window gaskets are in EPDM material.
