HURDEX Breathable House Wrap & Roof Underlayment 40 in x 33 ft (108 Sq Ft) - 170 GSM Heavy-Duty Weather Resistant Barrier, 3-Layer Waterproof Building Wrap for Sheds, Garages, Tiny Homes & Cabins

2-IN-1 HOUSE WRAP & ROOF UNDERLAYMENT - One roll handles both walls and roof on the same build. Use it as a breathable weather-resistant barrier behind siding or as synthetic roof underlayment beneath shingles, metal, or cedar roofing.

HEAVY-DUTY 170 GSM 3-LAYER BUILD - Spunbond polypropylene with 330 N tear strength, UV-stable for up to 6 months of sun exposure, rated -40F to 248F. Far tougher than lightweight house wrap, tar paper, or roof felt.

BREATHABLE YET WATERPROOF - The breathable middle film releases up to 1300 g/m2 of water vapor daily while blocking wind-driven rain and snow, letting walls and roof decks dry out for better moisture management.

SIZED FOR SMALL BUILDS - Ideal for sheds, detached garages, tiny homes, cabins, pole barns, chicken coops, and workshops. The 40 inch wide, 108 sq ft roll is right-sized for repairs and small projects with no waste.

FAST STAPLE-DOWN INSTALL - Roll it out, overlap seams 6 inches, and fasten with a hammer tacker or cap nails, then tape seams. Cut to size with a utility knife. Lays flat without wrinkling - no adhesives or peel-and-stick backing needed.
