A 84 Passivhaus HI version, with Uf transmittance value of only 0.76 W/m²K, has been developed for cool-temperate category (temperate and cold weather), becoming an ideal solution for buildings with low energy consumption in the vast majority of European territory. The glass itself acts as a structural element of the window, fixed to the profile by a special adhesive tape. In this way, it is possible to improve the transmittance while maintaining the rigidity of the assembly intact.
