Metal buildings are everywhere around Sapulpa, from shops and pole barns on acreage toward Kellyville and Mounds to commercial steel buildings along the highways. They go up quickly and cost less than wood framing, but bare steel is a poor insulator, and in our humid climate it creates a predictable problem: on cool mornings, warm moist air inside the building hits cold metal panels and condenses. Water drips onto tools, trucks, hay and equipment, and fasteners start to rust.
Closed-cell spray foam insulation solves condensation and heat at the same time. It bonds directly to the steel, so there is no cold surface for moisture to reach, it seals the seams and fastener holes, and it adds R-6 to R-7 per inch. A building that was unbearable in July and dripping in November becomes a usable shop, office or living space year-round.
Every metal building project starts with a free estimate. We measure wall height and roof area, look at doors, windows and existing insulation, and talk through how the building is used, because a cold storage barn and a heated barndominium need different thicknesses.
TipOld blanket insulation with torn facing is a moisture trap. If your building has the original vinyl-faced blanket and it is sagging or wet, it usually needs to come out before foam goes on.
Signs You Need Metal Building Insulation
- Water dripping from the roof on cool or humid mornings
- Rust spots around fasteners and seams
- The building is too hot to work in during summer
- Torn, sagging or wet blanket insulation
- Birds, wasps or rodents getting in at the eaves
- You plan to heat, cool or live in the space
How Much Foam a Metal Building Needs
For a shop or barn that is not heated or cooled, about 1 to 1.5 inches of closed-cell foam is often enough to stop condensation and take the edge off summer heat. For a conditioned shop or office, 2 to 3 inches is more typical, and barndominium living areas often get 3 inches or more in the roof with wall depth chosen to meet comfort and code targets.
Closed-cell foam is the standard choice on steel because it is rigid, bonds to the metal, resists moisture and adds strength to the panels. Open-cell foam is sometimes used on interior framed walls inside a barndominium. When a building will be occupied, code may require a thermal barrier or approved coating over the foam, and we include that in the quote when needed.

How It Works
Assess the buildingWe measure, check the panels and existing insulation, and discuss how you use the space.
PrepEquipment is moved or covered, doors, windows and the floor are masked, and failed insulation is removed.
SprayClosed-cell foam goes on the steel in passes to the specified thickness.
FinishWe apply any required coating, clean up and walk through the building with you.
