Sturdy Housewrap Engineered for Energy Efficiency
DuPont™ Tyvek® HomeWrap®
Sturdy Housewrap Engineered for Energy Efficiency
<br><b>DuPont™ Tyvek® HomeWrap®</b> is the original house wrap, leveraging advanced material science to keep air and water out while allowing water vapor to escape. This contributes to enhanced building durability by protecting homes from damaging wind and rain that can penetrate exterior cladding. <br><br> <b>Tyvek® HomeWrap®</b> is uniquely engineered by spinning extremely fine high-density polyethylene (HDPE) fibers that are fused together to form a strong, uniform web. This robust structure creates millions of tiny pores that resist bulk water and air penetration while allowing moisture vapor to pass through. <br><br> Additionally, <b>Tyvek® HomeWrap®</b> can reduce home energy bills by controlling air flow and water intrusion, thereby improving insulation performance and HVAC efficiency. It is designed to keep homes cool in the summer, warm in the winter, and dry all year round.

Features & Benefits
Ease of Installation
- Translucent, giving builders a convenient, clear view of studs and the sheathing surface during installation.
- Durable, with a polymer will not rust or rot, offering superior tear resistance compared to other leading non-woven, nonperforated wraps.
- Breathable, with a water vapor transmission rating of 5 perm minimum.
- Able to cling to the house with its unique surface during installation.
- Simple and quiet to install, helping make a quieter home while under construction.
- Compatible with standard adhesives and sealants.
Temperature and UV Resistance
- Withstands up to four months (120 days) of UV exposure.
- Maximum in-service temperature of 180° F.
Air and Water Barrier Performance
- Unique non-woven structure is breathable, allowing moisture vapor to pass through, promoting drying in wall systems, and helping to prevent mold and water damage.
- Stops air movement through walls, enabling insulation to perform closer to its full R-value, thereby contributing to a more energy-efficient home.
- Meets ASTM E2556, Type II standards for vapor permeable flexible sheet water-resistive barriers and type I air barrier when tested in accordance with ASTM E1677.
- Offers >90% drainage efficiency when tested in accordance with ASTM E2273.

FAQ
What is the Basis Weight of DuPont™ Tyvek® HomeWrap®? The basis weight and the value for HomeWrap® is 1.8oz/yd^2. What if the DuPont™ Tyvek® HomeWrap® has exceeded its exposure limit, does the building need to be re-wrapped? DuPont™ Tyvek® HomeWrap™, Tyvek® StuccoWrap®, and Tyvek® DrainWrap™ have a UV exposure limit of 120 days. If Tyvek® WRBs are exposed beyond the recommended limit, another layer of Tyvek® WRB can be installed over the existing layer, or the existing layer can be replaced. In either case, the new layer must be integrated with the window and door flashing per the applicable DuPont Installation Guidelines to ensure continuity of the drainage plane. If adding a new layer over the overexposed layer, the 2-layer system will have a lower permeability. Contact your local DuPont Building Envelope Specialist for more information.
