Episode Synopsis "How To Install House Wrap the right way"

·        Extend house wrap below the mudsill—for water management, but also for air sealing. Seal the bottom of the house wrap to the sheathing with caulk or tape. ·        Overlap the layers shingle-style as you go up the wall—like roofing shingles. ·        Overlap vertical seams 6-12 inches. ·        Overlap horizontal seams 6 inches (upper layer over lower layer). ·        Fasteners: use a cap nailer because slap staples leak. Tyvek says you can use 4 staples per 9 feet of house wrap if you tape over them an apply the siding right away. But a cap stapler is better.·        Apply house wrap up the gables before installing exterior trim, even if the attic is not conditioned. House wrap is not just for air sealing the insulated parts of the house, it is mainly for water management. If the gable isn’t covered, water can get to the framing, and even behind the housewrap below.·        Wrap and seal the underside of cantilevers. Better yet, add a solid sheet good to cover the bottom, and wrap over that.·        Tape the seams on flat house wrap with 2-inch tape; use 3-inch tape for wrinkled house wraps.Thank youFor more information visit our site www.swat.co.nz
