Expertly engineered to fuse unparalleled energy efficiency with sublime aesthetics, KLAR’s Passive Windows offer cutting-edge design solutions that are as kind to the environment as they are to design vision. Available with double or triple glazing, KLAR Passive Windows are produced with FSC-certified pinewood or aluclad. As compared to older double-glazing windows, which carry an insulating U-value of 3.0 W/m2K, KLAR’s triple-glazed windows are much more efficient at 0.8 W/ m2K. These triple glazed windows were installed in the Hotel Marcel, in New Haven, CT—the first Passive House-certified hotel in the country.
