In this episode of the Build Show Matt Risinger puts housewrap performance to the test to see if wet framing lumber can actually dry through modern weather barriers. Drawing on hard lessons from rainy Pacific Northwest builds and past mold issues, Matt explains why permeability matters and why builders should always verify moisture levels before closing in walls. Using a moisture meter, he compares dry lumber, soaked 2x4 samples, and boards wrapped in different materials—including a low-perm wrap, a high-perm peel-and-stick, a fluid-applied membrane, and even a sealed Ziploc bag. After nearly two weeks outdoors, the results reveal which wraps truly allow drying and help prevent hidden moisture problems.
