Integrated building envelope products for moisture protection, air sealing, and long-term wall performance.

Why builders choose DuPont Tyvek

DuPont Tyvek is one of the most recognized names in building envelope protection, with product systems built to work together across wraps, flashing, tapes, and fluid-applied barriers. The brand is widely specified when projects need dependable air and water management without sacrificing vapor permeability in the wall system.

Across residential and commercial construction, DuPont Tyvek products are used to protect walls and openings from wind-driven rain and moisture intrusion while supporting more controlled air performance. From HomeWrap and CommercialWrap to DrainWrap, flashing systems, and Tyvek Fluid Applied WB+, the product family is built around complete envelope continuity rather than one-off components.

What makes DuPont Tyvek different

  • Breathable weather protection

    Tyvek weather barriers are designed to hold out air and bulk water while still allowing water vapor to escape, helping wall assemblies dry more effectively and reducing moisture-related risk inside the system.

  • System-based envelope approach

    DuPont positions Tyvek as an integrated building envelope system, combining wraps, tapes, flashing products, and fluid-applied options so installers can connect critical transitions and vulnerable openings more effectively.

  • Residential and commercial flexibility

    The Tyvek lineup includes solutions for houses, multifamily work, and commercial assemblies, including products such as HomeWrap, CommercialWrap, DrainWrap, ThermaWrap LE, and Fluid Applied WB+ for different performance targets and wall conditions.

DuPont Tyvek FAQs

What is DuPont Tyvek used for?

DuPont Tyvek is used in building envelope assemblies to help manage air, bulk water, and moisture across walls and openings. The product family includes weather barriers, tapes, flashing materials, and fluid-applied solutions used in both residential and commercial construction.

Does Tyvek allow walls to breathe?

Yes. DuPont Tyvek weather barriers are designed to resist air and water intrusion while still allowing water vapor to pass through, which helps walls dry more effectively and supports long-term envelope performance.

What is the difference between HomeWrap, CommercialWrap, and DrainWrap?

Tyvek HomeWrap is positioned as the original house wrap for residential use, CommercialWrap is intended for commercial wall applications, and DrainWrap adds a surface design that supports enhanced drainage behind cladding where additional drainage performance is needed.

Are Tyvek tapes and flashing products only for windows and doors?

They are commonly used around windows and doors, but they are also important for sealing penetrations, transitions, and other vulnerable openings where water intrusion and air leakage can compromise overall envelope performance.
