Spray Foam Attic Insulation in Wyoming
Last updated:
Spray-foaming the underside of the roof deck turns a leaky vented attic into a sealed, unvented "hot roof" assembly. In Wyoming that means no more ice damming, no more wind-washed batts, and 25–40% lower heating bills. Seamless Systems builds unvented attic assemblies with closed-cell or open-cell foam depending on your structure.
What is attic insulation?
Spray-foaming the underside of the roof deck turns a leaky vented attic into a sealed, unvented "hot roof" assembly.

Seamless Systems builds unvented attic assemblies with closed-cell or open-cell foam depending on your structure.
What's included in attic insulation.
- Eliminates ice damming on the roof edge
- Brings HVAC ducts inside the conditioned space
- Stops wind-washing that destroys batt R-value
- Code-compliant unvented assemblies (IRC R806.5)
- Typical R-49 to R-60 hit on Wyoming attics
When to call Seamless Systems for attic insulation.
Ice dams on the eave, drafty rooms above the garage, cold floors over a crawl space, or a shop that swings 60°F in a day — those are the five tells a building is bleeding conditioned air through inadequate insulation. Spray foam is the highest-ROI fix in this climate.
- Ice damming on the roof edge in winter
- Drafty rooms or temperature swings room-to-room
- Heating bills that climb year over year
- A pole barn or shop you can't use in winter
- Condensation dripping off cold steel in a shop
- New build wanting the highest R per inch

Frequently asked
Questions we get most.
How do you quote a spray foam job?
We do not publish a public price list.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.
How do you quote a new garage door install in Wyoming?
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.
Are you licensed and insured?
Yes. Seamless Systems LLC is a licensed and insured Wyoming home services company, founded in 2016 by Cody Williamson with over 25 years of combined crew experience in garage doors, gutters, and spray-foam insulation.
What is the difference between open-cell and closed-cell spray foam?
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.
