The Andersen Design Pressure Estimator is available to registered users at www.andersenwindows.com/stormwatch. How It Works Users register at the Web site, then enter basic site and building information, including ASCE year, wind speed, exposure, building category and mean roof height. Builders can get more detailed information after entering window or door width and heights, and the wall zone or roof zone location. The program then estimates the overall DP rating for the structure’s windows and patio doors. A product finder identifies Andersen® products with Stormwatch™ protection — featuring impact-resistant glass — that meet or exceed the DP ratings estimated by the program. At that point, third party certified test report documentation for the products selected can be printed. Data for multiple projects can also be saved for access at a later time. “Building codes can be difficult to understand and time consuming to research. These online tools give builders an accurate estimation of the right windows and doors to satisfy design pressure and impact-resistance requirements,” said Steve Berg, specialty products manager at Andersen. “The added benefit of being able to access test reports and certification documents for the products selected will make it easier on everyone involved with a specific project,” Berg added. Stormwatch™ Protection Andersen® products with Stormwatch™ protection feature design pressure upgrades and various glass options, including High-Performance™ and High-Performance Sun™ impact-resistant glass, as well as clear and tinted monolithic impact-resistant glass. These products also offer many structural enhancements, including special fasteners; increased silicone glazing; and frame, sash and panel reinforcements to help guard against harsh weather conditions. Andersen products feature Perma-Shield® vinyl cladding, which resists the effects of salt water and sea air, and never needs painting.
