Fibrous Insulation Deep Dive

Matt Risinger sits down with builder Travis Brungardt on the Build Show podcast to dig into fibrous insulation, meaning any non-foam product that traps air between fibers. They start with fiberglass batts and blown-in loose fill, then move to cellulose and wood fiber, and they cover how installation quality and air movement affect real-world performance. The conversation looks at attics and walls, wind washing, settling, and the difference between rated and long-term R-value. They also touch on less common options like denim batts and blown-in blanket systems. The episode works as a companion to Travis's “Builders Installation playbook series and sets up a follow-up on rigid board insulation.
