Spray Foam Insulation Services

Insulation contractor serving the Kalispell, Bigfork, Somers, Lakeside, Whitefish, Columbia Falls and the Flathead Valley areas of Montana

Spray foam insulation is one of the most advanced and effective ways to insulate homes and buildings in Montana’s rugged climate. At True North Insulation, we specialize in closed-cell and open-cell spray foam applications that seal gaps, increase energy efficiency, and provide long-term comfort. Whether you're insulating a new build or upgrading an existing structure, spray foam forms an airtight barrier that helps you save on heating and cooling costs year-round.

Spray foam also adds structural strength and deters moisture and pests—making it a popular choice for both residential and commercial projects across the Flathead Valley.

Key Benefits of Spray Foam:

• Superior air sealing and insulation in one product
• Great for attics, crawlspaces, basements, and new builds
• Reduces energy bills by preventing air leakage
• Helps prevent mold and moisture buildup
• Adds structural integrity to walls and roofs
• Available in open-cell (more flexible) and closed-cell (more rigid, water-resistant) options
