DuPont™ Weathermate™ Plus Housewrap: Non-Woven, Non-Perforated Protection for Long-Term Weather Defense
When it comes to protecting a home from the elements, every layer matters. DuPont™ Weathermate™ Plus Housewrap is engineered to deliver maximum weather defense — providing durability, water resistance, and energy efficiency for years of comfort.
What Is Weathermate™ Plus Housewrap?
DuPont™ Weathermate™ Plus is a non-woven, non-perforated, polyolefin-based wrap designed to enhance a building’s weather barrier between the cladding and the wall assembly. It forms a continuous protective membrane that shields walls from damaging bulk water and air infiltration, reducing drafts and helping to maintain indoor comfort.
By minimizing air leakage, Weathermate™ Plus helps prevent energy loss, while its engineered water vapor permeability (over 5 perms) allows trapped moisture behind the wall to escape outward — helping walls dry from the inside out and reducing the risk of mold or rot.
Key Features and Benefits
Superior Protection
- Excellent water resistance prevents rain and wind-driven moisture from penetrating the structure.
- Air permeance of only 0.02 L/s-m² helps maintain a tight building envelope that reduces energy waste.
- Flame Spread < 25, Smoke Developed < 450 (ASTM E84) — Class A fire rating for added safety.
Built for Strength and Durability
- Tear Strength: 13 lbs min. (machine and cross direction)
- Grab Breaking Force: 40 lbs/in (machine) and 35 lbs/in (cross)
- Non-woven design resists rust, rot, and tearing — far outperforming many other wraps.
- UV-resistant and can remain exposed for up to 120 days before siding installation.
Breathable and Energy Efficient
- Engineered permeability (> 5 perms) allows vapor to escape, protecting sheathing and insulation.
- Reduces drafts for a more comfortable, energy-efficient home year-round.
Easy, Quiet Installation
- Translucent material offers a clear view of studs and sheathing for precise alignment.
- Clings naturally to walls, simplifying application.
- Compatible with standard adhesives, sealants, and DuPont™ flashing systems.
Standard Roll Sizes

Each roll is lightweight, easy to handle, and designed for efficient coverage on residential and light commercial projects.
Installation Highlights
Weathermate™ Plus Housewrap is best installed following DuPont’s recommended bottom-up shingling method to ensure proper water shedding:
- Start at the bottom corner of the structure and extend at least 1 inch over the sill plate or foundation.
- Overlap vertical seams by 6–12 inches and secure with fasteners spaced 6–18 inches apart on studs.
- Overlap upper layers over lower layers by at least 6 inches.
- Tape all seams using DuPont™ Weathermate™ Construction Tape for maximum air-barrier performance.
- Integrate properly with flashing and window/door openings using DuPont™ Sill Pan and Self-Adhered Flashing Products.
These steps create a continuous, water-shedding barrier that helps prevent moisture intrusion and structural damage.
