Recently, Wegner Insulation completed a full attic and crawlspace retrofit for a farmhouse on the outskirts of Ronan. The homeowners were struggling with frozen pipes and massive heat loss during the winter months. By applying closed-cell spray foam to the foundation and high-density blown-in insulation in the attic, we successfully stabilized the indoor temperature and eliminated the risk of pipe bursts, significantly increasing the home's seasonal resilience.

Given our harsh winters and hot summers, spray foam is often the top choice because it provides both a high R-value and an airtight seal, preventing the cold Montana wind from penetrating your walls.
Spray foam is a permanent solution. Once applied, it does not sag, settle, or degrade over time, meaning it will protect your Ronan property for the entire lifespan of the building.
Yes! While many focus on winter, quality insulation keeps the heat out during our dry summer months, allowing your AC to run less frequently and more efficiently.
Absolutely. We frequently use agricultural spray foam in barns and shops to help regulate temperatures for livestock and prevent condensation that can lead to rust and mold on equipment.
Yes, specifically open-cell spray foam and mineral wool are excellent at absorbing sound, making them ideal for homes near busy roads or for commercial offices in Ronan.
Insulation resists heat flow, while air sealing stops the physical movement of air. Using spray foam allows us to achieve both simultaneously, creating a much more effective thermal barrier.
