Matt Risinger sets up a hands-on experiment on the Build Show, framing it around the real toll of electrical fires in American homes each year. He builds four identical wall mockups—one empty cavity, one with canned spray foam, one with fiberglass, and one with mineral wool insulation—then ignites simulated electrical fires inside each using fire-starter cubes. Watching how flames spread, smolder, or self-extinguish across the different materials, he tracks smoke, char, and structural damage in real time before opening the walls to inspect the aftermath. The test reveals meaningful differences in how insulation type affects fire containment within standard interior wall framing, offering practical insight for builders weighing sound control against fire safety.
