Insulating Your Montana Home: Spray Foam, Attics & Energy Efficiency

Is your home losing heat through the attic? Is your insulation old, compressed, or simply not enough for a Montana winter? In this episode of the Your Home Montana Podcast, Mark Junker sits down with Donny Morton, co-owner of Bulletproof Insulation, to talk about insulation, air sealing, spray foam, and some of the most common energy-efficiency problems found in Montana homes. Donny shares how a house he didn't buy unexpectedly led him into the insulation business and how Bulletproof Insulation has grown since 2019. They also break down the differences between spray foam, blown-in, and batt insulation, why attic ventilation and air sealing matter, what can cause recurring ice dams, and how homeowners can identify areas where their house may be losing energy.
