It is the basis of the thermal insulating ELVIAL multilock systems. Impressive level of water resistance and air permeability of 450 Pa certified for double sash opening frame in the largest dimensions (1.50 m x 2.30m). This level refers to a strong storm of 10 Beaufort and 89-102 Km/h wind speed.
HIGH THERMAL INSULATION
- Uf : 1.76-2.16 W/m2K
- Uw*: 1.5 W/m2K with double glazing (Ug 1.0)
- Uw*: 1.3 W/m2K with triple glazing (Ug 0.6)
Insulation levels:
- Optimized foam-filled insulation zone (ELVIAL I2 Technology) that ensures excellent isothermal flow of the window.
- Specially designed central gasket with 5 cavities that covers all the polyamide surface, glazing gaskets with fins and perimetrical insulationwith low density polyethylene, for effective heat transfer minimization.
SECURITY
- Water tightness: 900Pa in single sash with fixed sub-light (13 Beaufort cyclone)
- WK2 Security Level, with up to 21 locking points around the window
