New enerGfacade storefront and curtain wall systems deliver best-in-class thermal performance for energy efficient building envelopes Greenbuild 2010 AUSTELL, Ga.--(BUSINESS WIRE)--YKK AP America today expands its enerGfacade® product line with the addition of its YCW 750 XT curtain wall system and YES 45 XT storefront system for the commercial building market (see video here). With their XT designation, the two products offer a superior grade of thermal performance for storefront and curtain wall applications. The enerGfacade product line improves insulation and increases resistance to energy loss across the entire building façade, while exceeding the industry’s most stringent green standards, including ASHRAE 189.1. o achieve the highest levels of energy efficiency and unmatched thermal performance, the YCW 750 XT curtain wall system incorporates a dual thermal barrier design engineered to integrate standard one inch insulating glass and advanced glazing technologies including suspended films and triple glazing. Its high thermal performance delivers U-factors of 0.37 using standard one inch low-e glazing and U-factors as low as 0.17 with advanced glazing. In addition, it includes the seamless ability to integrate the curtain wall with the building’s air vapor barrier for improved energy efficiency. Glazing units are supported by innovative structural supports that transfer dead loads away from the thermal barrier and its warmer interior surfaces improve occupant comfort and condensation resistance.
