DuPont Tyvek® HomeWrap (1055B)

Product Description

DuPont™ Tyvek® HomeWrap is the original house wrap, incorporating unique material science that helps keep air and water out, while letting water vapour escape.

As a result, it can contribute to improved building durability by helping to protect homes against damaging wind and rain that can penetrate the exterior cladding. 

DuPont™ Tyvek® HomeWrap can also reduce home energy bills by controlling air flow and water intrusion, which helps insulation work better, allowing the HVAC system to work more efficiently. It’s a house wrap engineered to keep homes cool in the summer, warm in the winter, and dry all year round.

How It Works:

The unique nonwoven structure of DuPont™ Tyvek® HomeWrap makes it breathable, allowing moisture vapor to pass through. This helps promote drying in wall systems, to help prevent mold and water damage. In addition, DuPont™ Tyvek® HomeWrap stops air movement through the walls, helping insulation perform closer to its full R-value, to provide a more energy-efficient home.

Not All House Wraps Are Equal:

The superior performance of DuPont™ Tyvek® HomeWrap is what separates it from other types of house wraps, as shown below.


Low Perm Microporous Film Wall Underlays:

A low perm, microporous film wrap is manufactured in a two-part process, where a coarse fabric backing with no protection for a building is laminated with a fragile film, in order to pass minimum requirements for water and air resistance. The film layer is delicate and routinely compromised in the real world through tearing and abrasion. These products can perform well in controlled conditions, but they are a problematic choice for real world workers and job sites.

DuPont™ Tyvek® HomeWrap is Very Different: 

The DuPont Building Envelope system consists of products specifically designed for proper moisture and air management within wall systems. Tyvek® WB is a uniquely engineered product made by spinning extremely fine high-density polyethylene (HPDE) fibers that are fused together to form a strong, uniform web. The tough structure of Tyvek® is engineered to create millions of extremely small pores that resist bulk water and air penetration, while allowing moisture vapor to pass through.

Ease of Installation:

DuPont™ Tyvek® HomeWrap™ is easy to install. It is pliable, so it readily wraps around corners, interfaces at joints, and wraps over unique architectural geometries.

Light weight, easy to handle, and fast to install, DuPont™ Tyvek® HomeWrap® is available in 2740mm width rolls, to help minimize seams and offer the potential for reduction in labour.

DuPont™ recommend the use of seam tape (DuPont™ Tyvek® Tape) and penetrations are sealed to ensure an air-tight wall underlay is maintained.

Support Throughout The Building Process:

In addition to its superior performance, DuPont™ Tyvek® HomeWrap is backed by the quality, integrity and building science resources of DuPont, the company that invented the building wrap category, including:

  • 10-year limited warranty from DuPont™.
  • Support from the DuPont™ Tyvek® Building Knowledge Center. From the latest updates on building codes to on-site consulting and training on DuPont Building Envelope Systems, a local DuPont™ Tyvek® expert can help you  make sure the job gets done right.
