Wegner Insulation delivers professional spray foam insulation services to homeowners and businesses throughout Somers, MT, and the surrounding Flathead Valley. Whether you're building new, retrofitting an older structure, or trying to cut energy costs, our team brings the right materials and experience to every project.



Somers sits right on the north shore of Flathead Lake, and anyone who lives here knows that winters don't mess around. Cold air seeps through gaps in framing, around windows, and through poorly insulated walls and attics. Proper insulation is what keeps your heating bills reasonable and your indoor comfort consistent from November through March. We've insulated homes, barns, and commercial buildings across the valley, and we understand what Flathead County structures actually need to perform in this climate.




A property owner near Somers Bay had a detached workshop with uninsulated walls and a metal roof that turned the space into an icebox in winter and an oven in summer. Our team applied closed-cell spray foam to the walls and ceiling, sealed around all door and window frames, and added a thermal barrier coating over the exposed foam. The owner reported the workshop went from unusable in January to comfortable enough for year-round woodworking projects.

Closed-cell foam is denser, has a higher R-value per inch, and adds structural rigidity, while open-cell foam expands more to fill irregular spaces and costs less per square foot.
Absolutely, we handle agricultural spray foam for barns, shops, chicken coops, and other outbuildings throughout the Somers area and surrounding communities.
