A Case for Self-Adhered WRBs

If you're re-siding your house or fixing up an older wall, there's a newer material worth knowing about: peel-and-stick house wrap. This is a membrane that goes between your siding and the sheathing (the wood panels under it) to keep water out and cut down on drafts. Instead of being stapled on like traditional house wrap, it has an adhesive backing that sticks directly to the wall, so there are far fewer holes for air and water to sneak through.

The upside for a homeowner is durability and comfort. Because it bonds tightly to the wall, it doesn't flap in the wind during construction, resists tearing, and blocks air leakage better than stapled wrap. That matters most in renovations, especially on older homes with wood-plank sheathing that has lots of gaps and seams. This material can bridge those gaps in one step, something that's normally slow and tricky to seal with tape or foam. It also holds up well in wet, windy, or coastal locations, and on homes with little roof overhang to shield the walls.

The tradeoff is cost: this material generally costs more than standard house wrap, though the price gap narrows compared to other premium options like liquid-applied coatings or pre-wrapped sheathing panels. Getting a good bond also depends on installation conditions, like a clean, dry surface and the right temperature, so results can vary. If you're planning a re-side or a major exterior renovation, this is a product to ask about and compare against what your contractor normally uses.
