Both the Majestic and Crown Series products offer protection from the sun’s harmful ultraviolet rays while addressing heat conservation issues. Combating the harmful effects of ultraviolet light will assist in reducing deterioration of window treatments, home furnishings and floorings. Low-emissivity (low-e or the ability to block heat & ultraviolet light) glass options dramatically reduce the ultraviolet light’s ability to enter your home. Additionally, reflecting heat, whether internally or externally, is a concern of all home owners from an economic and ecological standpoint. Think smart and inquire about International Window’s low-e glass options to save, in more ways than one!
