Spray-Foam Insulation
in Wyoming & the Black Hills

We do not publish a public price list. Every spray foam quote is tailored after a free on-site inspection — we measure the area, confirm open-cell vs closed-cell, and pick the thickness that hits the R-value you actually need. Use the spray foam calculator on the site to send us your specs and we will email a quote the same day.

Every install is quoted after a free on-site visit so the number matches the actual scope — size, insulation grade, opener, and whether we are hauling off an old door. Use the garage door calculator on the site to send us your specs and we will email back a tailored quote the same day.

Open-cell foam is softer, lighter, has an R-value of about 3.5 per inch, and is great for sound dampening in interior walls and roof decks. Closed-cell foam is denser, has an R-value of about 7 per inch, adds a vapor barrier, and increases structural rigidity — common in our region for unconditioned shops, metal buildings, and exposed crawl spaces.

Closed-cell spray foam typically runs $1.00 to $4.50 per board foot installed (one inch over one square foot), depending on access, thickness, and substrate. For an accurate number on your project, use our spray foam calculator or schedule a free on-site inspection — we email a tailored quote the same day.

A new single-car insulated steel residential garage door installed in Wyoming typically falls in the $1,400 to $2,800 range, and a double-car door in the $2,200 to $4,500 range, depending on insulation grade, window options, opener, and removal of the old door.

Yes — Seamless Systems is a local insulation contractor serving the Black Hills region (Belle Fourche, Spearfish, Sturgis, Deadwood) and northeastern Wyoming. We specialize in spray-foam insulation for attics, crawl spaces, and metal buildings — built for high-altitude cold and Black Hills winter conditions. Free on-site inspection and R-value plan.

Open-cell spray foam is softer and lighter, expands to about 100× its liquid volume, has an R-value of roughly 3.5 per inch, and is best for sound dampening, interior walls, and roof decks. Closed-cell spray foam is denser, expands only ~30×, delivers R-7 per inch, acts as its own vapor barrier, and adds structural rigidity — which is why we use it in Wyoming pole barns, unconditioned shops, and rim joists where moisture and cold are the main enemies. Closed-cell costs more per board foot but you need less of it to hit the same R-value.
