The document reports recent testing outcomes, including service-pipe penetrations in 5-ply CLT and closure penetrations in unprotected and protected assemblies, and outlines the Phase 1 project objectives and supporting learning materials. Key concepts include heat transfer fundamentals, standard fire exposure time-temperature curves, wood charring behavior, and how penetrations create additional heat paths relevant to firewall
