Expert Answers for Missoula Property Owners

What is the best insulation for Missoula’s cold winters?

Spray foam, specifically closed-cell, is highly effective in Missoula because it provides a superior R-value per inch and creates an airtight seal against the bitter Montana wind that traditional batts can't achieve.

How does air sealing help with my energy bills?

Air sealing stops the "stack effect," in which warm air rises through your attic and pulls in cold air from your basement or crawlspace. By plugging these leaks, you drastically reduce the workload on your HVAC system.

Can you insulate an existing home without a full renovation?

Yes, we frequently use blown-in insulation for attics and specialized techniques for wall cavities to improve a home's thermal performance without requiring major demolition or construction.

Is spray foam safe for residential use in Montana?

Absolutely. When installed by professionals like Wegner Insulation, spray foam cures into a stable, non-toxic barrier. It actually improves indoor air quality by preventing the infiltration of outdoor allergens and dust.

Does insulation help during the smoky summer months?

Yes, a properly air-sealed and insulated home keeps outdoor pollutants and wildfire smoke out of your living space, ensuring a healthier indoor environment when the air quality outside is poor.
