Blow-In Insulation Explained
Blow-in Fiber Insulation consists of fiberglass, fire-retardant cellulose, or denim fibers. Loose fill fibers are machine-blown into a cavity and they create an air barrier to help prevent heat transfer through your floors. Similar to batt insulation, blown-in fibers can compress and are not suitable for protecting against moisture intrusion. If you’re suffering a musty crawlspace, you’re noticing moist, wet floors, or you’re seeing your hardwood floors cup, there is likely a greater issue of trapped and lingering water under your home.
