Certified by the Passive House Institute for use in extremely cold climates, Zola Arctic, a new offering from Zola Windows, is a premium performance window that can be used in buildings across a broad spectrum of temperatures and climates. A timber-aluminum frame, PU-foam insulation, thermal glazing, and a superspace triple seal with butyl as a secondary seal combine to create a window with an R-value of 15 (a typical Energy Star window has an R-value of between 2.5 and 3.7). Zola Arctic has a visible light transmittance of 64 percent that allows for maximum daylight, uses German concealed hinges—available in marine grade stainless steel for coastal conditions—and has a powder-coated aluminum exterior for durability and longevity. The Fixed Windows can fit openings as large as 8 feet wide and 10 feet high, while the Tilt & Turn Windows can fit expanses as large as 5 feet wide and 9 feet high.
