New Construction, Additions & Shops in Missoula, MT

Spraying foam into open framing before drywall is the cheapest, most effective time to use it, and new builds in Lolo, Frenchtown, and the growing subdivisions around town can seal the full cavity and rim joists so the house clears Zone 6 code the day it's framed instead of chasing air leaks after the drywall goes up. Additions, gut remodels, and finished basements are the same story — anywhere the cavities are open is a candidate; a finished, drywalled wall is a job for dense-pack, not spray foam.

Metal shops, pole barns, and equipment sheds out toward Huson, Frenchtown, and the Bitterroot have their own problem: a bare steel roof has almost no insulating value, so warm interior air hits the cold panel and condenses — the "shop sweat" that drips on tools, rusts fasteners, and rots framing. Closed-cell foam sprayed directly to the underside of the steel raises the surface above the dew point, seals every seam and screw penetration, and adds real racking stiffness — the reason nearly every heated shop we foam around here, in a valley that swings hard between day and night temperatures, gets closed-cell run straight up the roofline.
