Local Insulation
What our coverage looks like around Bonners Ferry
Bonners Ferry sits in Boundary County, where the heating season is long and air leakage drives a large share of the heat loss in a building. Closed-cell spray polyurethane foam is the only insulation we install, because it air-seals and insulates in the same pass on roof decks, crawl space walls, rim joists, and metal building panels.
Crews are local to the region rather than subcontracted from out of state, and project scope is set against the code and assembly requirements that apply to your specific building.

Cold-climate work
What spray foam fixes for Bonners Ferry buildings
Cold floors and drafty rooms
Closed-cell foam on rim joists and in the crawlspace fixes the cold-floor problem most Bonners Ferry homes deal with every winter.
High heating bills
Sealing the envelope reduces the air leakage your furnace has to make up for. How much you save depends on the building, the fuel, and how leaky it was to begin with.
Metal building condensation
Closed-cell foam applied to the underside of prepared metal panels keeps humid interior air off the cold panel, which is what causes the drip in shops, ag buildings, and warehouses.
Ice damming on the roof
Air-sealing the attic plane with foam stops the warm-air leak that causes ice dams in our climate.
Cold, damp crawl spaces
Closed-cell foam on crawl space walls and rim joists, paired with a sealed liner, addresses the cold floors and damp air that show up every winter.
Cold storage and refrigeration
Closed-cell foam is the right insulation and vapor barrier for refrigerated rooms and walk-ins.
