It is a 84 mm deep hinged system with 6 interior chambers and steel reinforcement with thermal break. This window has been certified for the warm-temperate category (Uw ≤ 1.0 W/m²K) by the prestigious German Passivhaus Institut and can reach a Uw transmittance value of only 0.74 W/m²K, making it an ideal solution for low energy consumption buildings in areas with warm and temperate climates, such as the Spanish geography. It has a maximum glazing capacity of 54 mm and acoustic insulation of up to 46 dB, contributing to the reduction of heating and air conditioning consumption, and offering exceptional comfort at home.
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 1.0 system is elegant with clean lines and is offered in a wide range of finishes including white, colour, bicolored, wood imitation and metallic . It is available in both window and balcony versions with maximum sheet sizes of 1,400 mm wide by 2,400 high, weight of up to 130 kilos per sheet, and the possibility of internal opening, including casement, tilt-and-turn, parallel tilt-and-slide or folding.
