Windows with an R-5 value (or a U-factor of 0.2) represent the industry’s top tier of energy-efficient windows. The VPP allows window companies that have qualifying products to promote products through the designated website.
Builders visiting the DOE’s VPP website may select a size range with its associated cost range. After the size is chosen, a list of links to qualified manufacturers will appear. At this time, when users may click on Kolbe and the link will take them to the Kolbe website’s “where to buy” section. Entering a zip code enables visitors to receive contact information for distributors in their region.
The Kolbe Windquest® EP Series are among the products available on the DOE’s VPP website. These low-maintenance, long-lasting casement and studio windows exceed 2010 ENERGY STAR® criteria for all U.S. climate zones. A 1-1/4-inch, triple-glazed system helps these products achieve the required energy performance ratings needed to be part of the VPP.
