Tyvek AtticWrap breathable roofing membrane forms vent channels beneath the roof sheathing that generate a dynamic air flow from soffit to ridge. This concentrated roof ventilation helps dissipate attic moisture in cold weather and reduce heat buildup in warm weather more efficiently than traditional attic ventilation, providing a 20 percent reduction in heating and cooling costs, says the company. Furthermore, the product is the first to completely seal the building envelope, creating drier, healthier living spaces by helping to eliminate dust, pollen, and insects in attic spaces, the firm says. 800-448-9835. www.construction.tyvek.com.
