A stout weather barrier for commercial building envelopes, DuPont™ Tyvek® CommercialWrap® controls air leakage, stops water infiltration and prevents mold by allowing water vapor to escape.
An air and water barrier made to stand up to the rigors of commercial job sites, with high tear-strength, durability, and up to nine months of UV resistance. DuPont™ Tyvek® CommercialWrap® building wrap is one of the easiest ways to make a significant difference in energy efficiency and overall building performance. Tyvek® CommercialWrap® can help in three vital areas, as part of a building envelope system: controlling air leakage, which can impact the efficient operation of HVAC systems, costing the commercial building sector billions each year; preventing water infiltration, which can reduce the effectiveness of insulation, and cause wood damage and corrosion; and allowing water vapor to escape when moisture does get in, letting wall systems dry, helping prevent mold, and protecting and improving building air quality.
