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.

• Designed to allow up to nine months of UV exposure
• Tough and tear-resistant to ensure durability
• Allows water vapor to escape to help improve indoor air quality
• Helps prevent mold
