• Aluminium profiles were manufactured in Tehnomarket’s own extrusion factory. The raw material used is primary aluminium alloy AlMgSi0.5 (AA 6063 and AA 6060) with minimum tensile strenghth of 210 KN/mm².
• 16mm wide Polyamide stripes (PA 6,6 with 25% glass fibers) connect inner and outer aluminium parts into finished profiles, and beside functioning as a mechanical bond they also prowide a thermal break. Guaranteed shearing force for profiles connected with polyamide stripes is strictly controlled during production.
• The double sealing between frame and sash is achieved with two separate EPDM gaskets resistant to UV light – the so-called “central system”
• Drainage holes on the bottom of frame allow for incidental water drainage and outer chamber ventilation
