Tyvek HomeWrap by DuPont
What it is:
- Tyvek HomeWrap is a high-performance building envelope material from Tyvek/DuPont designed to act as an air- and water-resistive barrier (WRB) behind exterior cladding.
- It is a non-woven sheet made by spinning high-density polyethylene (HDPE) fibers and bonding them into a web. This structure is engineered to block bulk water penetration and air infiltration, while allowing moisture vapor to escape (breathable).
- It is installed over the sheathing of a building (walls) and then the exterior cladding (siding, stucco, etc) is installed on top. It helps protect the wall assembly from wind-driven rain, air infiltration and supports drying of moisture.
- Available in multiple roll sizes (widths, lengths) to suit different wall heights and projects.
Key Specifications & Performance Features:
Some of the standout performance data for Tyvek HomeWrap:
- Air infiltration resistance: Tested as less than 0.004 cfm/ft² @ 1.57 psf (ASTM E2178) for the product.
- Water-vapor transmission (breathability): Approx ~400 g/m²-24 hrs (≈ 56 perms) in one test method.
- Drainage efficiency (ability to shed water behind cladding): >90% in ASTME2273 test.
- UV exposure resistance: The product can withstand up to approximately 120 days of direct UV exposure (i.e., before siding/cladding is installed) in its standard form.

About this product…
Tyvek HomeWrap by DuPont is the original ‘House Wrap’, engineered to help keep homes cool in the summer, warm in the winter, and free from moisture all-year-round.
Made by spinning extremely fine high-density polyethylene (HPDE) fibers fused together to form a strong, uniform web, the tough yet flexible structure of Tyvek® is a unique one. It is pliable, so the material wraps around corners, interfaces at joints, and bends over architectural elements with ease. It is also light weight, easier to handle, and faster to install than the average house wrap. Perforated house wraps require “micro-perforations,” or thousands of holes, aiming for breathability, but giving water and air a way in. These wraps give up a great deal of resistance to air and water penetration in order to achieve some level of vapor permeability, but can lead to the potential for water damage and make insulation less effective, and to higher energy costs.The material formulated with Tyvek® HomeWrap by Dupont is uniquely engineered to create millions of extremely small pores that resist bulk water and air penetration, while allowing moisture vapor to pass through. This promotes drying in walls by allowing moisture vapor to pass through, while protecting homes against wind and rain that can penetrate through exterior cladding. This system reduces home energy bills by controlling air flow and water intrusion–aiding in insulation–allowing the HVAC system to work more efficiently.
There are seven different sizes to choose from – 3’ x 100’, 3’ x 165’, 5’ x 200’, 9’ x 150’, 9’ x 400’, 10’ x 100’, and 10’ x 150’.
These three profiles range in thickness, and general ability to withstand differing materials. The DuPont 120 and 160 can underlay materials like asphalt shingle, cedar, or metal, while the DuPont 200 can underlay an addition of cladding, tile, and slate. All profiles are designed for slopes 2:12 and above.
