Expert Verdict — Reviewed by the SuperArbor Pro Desk
Woven, coated housewrap like REX Wrap Plus balances tear resistance during installation with the vapor permeability walls need to dry. Roll it out horizontally from the bottom of the wall up, shingling upper courses over lower ones, and integrate it with flashings at windows and penetrations rather than relying on tape alone. At 877 sq ft per roll, one roll typically handles a good-sized elevation; order an extra roll for waste on complex elevations.
Watch footing on elevated scaffolding when unrolling wide housewrap in wind, and secure loose edges promptly to prevent tearing.
Order Alpha ProTech REX Wrap Plus housewrap to protect and dry your wall assemblies.
