One tiny overdrive and your “sealed” wall becomes a sponge.
When it comes to weather-resistant barriers, can a factory-coated OSB panel really stand up to the elements? In this week’s discussion, Dave Stutzman, Steve Gantner, and Elias Saltz break down a hot topic from LinkedIn—untreated fasteners in coated OSB WRB panels—and why small installation missteps can lead to big moisture problems. From swelling and mold to vapor drive and double vapor barriers, they explore the risks, alternatives, and “belt-and-suspenders” strategies that keep water out for good. Whether you’re in blazing heat or frigid ice rink conditions, one truth stands: shed the water to the exterior.
