House Wrap & Tape

House Wrap & Tape create a continuous weather-resistive barrier that protects sheathing from bulk water while allowing trapped moisture to escape. By reducing air infiltration and sealing seams, they improve energy efficiency, cut drafts, and help HVAC systems work smarter. Used under siding, brick, and stucco on new builds and retrofits, a well-detailed building envelope prevents leaks, mold risk, and costly callbacks.

Modern house wraps come in woven and non-woven versions with different perm ratings. Look for vapor-permeable membranes that shed rain yet let walls dry, or choose drainable wraps with integrated channels for faster drying behind cladding. UV exposure ratings matter if the wrap will sit uncovered; longer ratings give flexibility on job timelines. Pair the wrap with compatible sheathing tape to seal horizontal and vertical seams, and use butyl or hybrid flashing tapes for windows, doors, and penetrations. Cold-weather acrylic adhesives, high-tack options, and primer compatibility help ensure strong bonds across seasons.

Installation is straightforward with the right approach:
- Install shingle-style from bottom to top with proper overlaps.
- Tape every seam, corner, and fastener penetration; roll tapes firmly for full adhesion.
- Flash rough openings in the correct sequence: sill, jambs, then head flashing.
- Use cap fasteners or a cap stapler to reduce tear-through and improve hold.
- Integrate with roof and foundation flashing to maintain a continuous barrier.
- Follow the wrap and tape manufacturer’s compatibility and temperature guidelines.

Pros and DIYers alike rely on house wrap systems to meet code, pass blower door tests, and build durable, energy-efficient homes. Choosing the right combination of house wrap, sheathing tape, and flashing tape—plus the right knives, rollers, and applicators—delivers reliable moisture control, tighter air sealing, and long-term performance behind any exterior finish. Match products to climate, siding type, and schedule to maximize performance overall.
