While not visible to the naked eye, there’s actually a lot of green here — as in energy efficiency and improved indoor air quality. At the heart of the system is TYPAR® HouseWrap, which reduces the risk of air and moisture infiltration that could ultimately waste energy or lead to mold. When you add those benefits to the system’s ENERGY STAR® and LEED® qualifications, there’s no denying that TYPAR is in fact green.
