 Premium Wood ConstructionNatural wood serves as one of the most energy efficient materials available. Windsor uses only the finest wood interiors of Clear Select Pine, Natural Alder or Douglas Fir.
 Cardinal® LoE 366 GlassWindsor products feature LoE 366 glass with a coating that alters the way glass transmits visible and invisible light. LoE 366 decreases heat loss in the winter and heat gain in the summer. Reduced ultraviolet light penetration also helps prevent your furniture, drapes and carpet from fading.
 Extruded AluminumWe use only heavy-duty .050 extruded aluminum cladding, versus thin roll form aluminum. It is sturdier and more resistant to exterior damage, including dents and chips. The powder coat used in our paint application is the extremely durable 2604 finish. The 2605 finish is available when your project requires an even stronger defense against the elements.
 Tape & Silicone GlazedWe use silicone and tape glazing methods to ensure a water-tight seal and slow the conduction of heat and cold.
 Super Spacer® Technology Super Spacer dual-seal
moisture barrier technology provides one of the most thermally efficient
spacers in the marketplace, meeting or exceeding ENERGY STAR®
guidelines in all zones. All-foam Super Spacer reduces heat and cold
conduction, which results in more comfortable living for homeowners
and fewer callbacks for builders.
