A 84 PASSIVHAUS HI // The best thermal performance in the market


This PVC series offers a Uw transmittance value of only 0.66 W/m²K, overturning the traditional German brands as the system with the best thermal performance on the market.

Certified by the prestigious German institute Passivhaus, it becomes the ideal window for low-energy buildings in the vast majority of European territory.

84mm depth hinged system with profiles including 6 interior chambers and insulating foams inserted both in frame and sash that allows to achieve the best thermal performance in the market. With a transmittance value Uw from only 0.66 W/m²K, this window has been certified for the cool-temperate (cold and temperate climates) category by the prestigious German Passivhaus Institut, becoming an ideal solution for buildings with low energy consumption in the vast majority of European territory. It has a maximum glazing capacity of 56 mm and acoustic insulation of up to 46 dB, offering exceptional comfort inside the rooms. Furthermore, the glass itself acts as a structural element of the window, fixed to the profile by a special adhesive tape. In doing so improving the transmittance while maintaining the rigidity of the assembly intact.

All these benefits are reinforced by the great results achieved in the AEV test benches: Class 4 in air permeability, Class E1500 in watertightness and Class C5 in wind resistance. As well as the entire CORTIZO PVC range, the new A 84 PASSIVHAUS 1.0 also stands out for the quality of its profiles: CLASS A (main wall thickness of 3 mm), CLASS S (suitable for severe climates; optimal solar behaviour) and CLASS II (maximum impact resistance).

The A 84 PASSIVHAUS system has an elegant aesthetic with clean lines and is available in a wide range of finishes in white, color, bicolor, wood effect, and metallized. It is available both as a window and a balcony with maximum dimensions per sash of 1300 mm wide and 2200 high, with a weight of up to 100 kilos per sash, offering the possibility of inwards opening, whether side hung, turn & tilt, tilt & parallel, or bottom hung.
