In this episode of the Build Show, Matt Risinger breaks down how to build one-hour fire-rated wall assemblies that meet code—especially for homes in the wildland urban interface. He walks through two different tested assemblies using innovative fire-resistant sheathing that eliminates the need for exterior gypsum while still allowing full flexibility with exterior cladding.

Matt explains how to properly follow ICC reports, select approved sealants, and handle penetrations and joints to maintain a true rated assembly. He also dives into next-level strategies for improving air sealing and water management, including fluid-applied barriers and best practices that go beyond just fire protection.
