Just a couple of years ago, there was a fire in London which was caused by exterior rigid foam. The fire spread quickly, and many lost their lives. Today we'll talk about a fire resistant, non-combustible, sound absorbent, and water repellant alternative.
Master builder, Matt Risinger, is on a job site where he's building a new custom home, his LVL frame house. In this video, Risinger talks to us about the benefits of using Comfort Board 80, stonewool insulation, which is made of rocks. It's good up to 2,000 degrees. (Don't believe him? He'll take out his lighter and show you.) Here Matt's using a 2-inch wide product blanketing the entire house. It covers over his studs and reduces thermal bridging. The insulation on the outside brings a lot of value to the house.
How is this different from other exterior insulations he's used before? It's made of 40% recycled content. There's also no drift in the R value. Since it's made of stone, there's barely any expanding and contracting happening. It will stay completely rigid, which means he can do what he needs to do in one layer as opposed to two.
Another added benefit: bugs don't like it. It's also vapor-permeable, when compared with others that are zero permeable.
Sound absorption properties are another perk of using Comfort-Board 80. Watch the product in action.
