Wausau Window and Wall Systems
SuperWall™ system, ClearStory™ sun shades
Wausau curtainwall and ClearStory™ sun shades were used to ensure the exterior of the convocation and sports center’s new two-story addition design complemented the original building. Wausau’s SuperWall™ system two-sided structural glazing and 90-degree corners. Glazing contractor Zephyr Aluminum of Wilmington, Del., installed the 8,000 square feet of curtainwall systems plus sun shades.
Exterior sun shades intercept unwanted solar heat gain before it can impact a building’s HVAC system’s load. Sun shades also can economize natural light by redirecting it inside the building. “Lighting accounts for 40% of the energy used in a typical commercial building. Properly executed, daylighting can reduce HVAC peak loads with corresponding reductions in mechanical equipment capacity and carbon footprint,” notes Gille. In climates like Delaware where snow and ice loads may be heavy, he also advises that engineers pay particular attention to the connections between sun shades or outriggers and the curtainwall mullion profiles.
For The Bob, Wausau’s sun shades, framing and accent aluminum were finished by Linetec in a clear anodize. This finish meets the AAMA 611-98 specification, which anodize finishes to meet rigorous testing performance standards including 3,000 hours of salt spray resistance. Linetec’s Schroeder notes its other benefits: “Unlike other finishes, as an integral part of the substrate, anodizing highlights aluminum’s metallic appearance. Anodized aluminum is 100% recyclable, contains no VOCs, and resists the ravages of ultraviolet radiation, temperature, corrosion, humidity and warping — adding to its long life-cycle.”
