N14300

Three chambers casement system with a depth of 64mm on fixed frames and 72mm on vents.
With a thermal coefficient of Uw=1,4W/m2K (N14 300 with a view of 126mm), power consumption can be significantly reduced, consequently decreasing CO2 emission.
The increase of the N14 300 system profile depth improves the functional, thermal, acoustic and safety performances.
