Barndominiums are popular around Tulsa, especially on acreage in Coweta, Claremore, Collinsville and Sapulpa. They combine a steel building shell with full living space, and that combination brings unique insulation challenges. Steel conducts heat quickly, metal panels have many seams, and indoor humidity from cooking, showers and people can condense on cold metal if it is not insulated correctly.
Closed-cell spray foam applied directly to the inside of the metal walls and roof solves all three problems. It creates a continuous air seal, adds high R-value per inch, and keeps the steel surface above the dew point so condensation does not form inside your walls. The result is a home that is quiet, energy-efficient and comfortable in every room.
Because a barndominium is your home, we plan the insulation with your builder and HVAC contractor. Your free estimate covers foam type and thickness for the roof, exterior walls and any shop area.
Tulsa tip
Coordinate with your HVAC contractor before insulation. A spray-foamed barndominium is very tight, so the system should be sized for the actual heat load and include fresh-air ventilation.
What a Barndominium Insulation Plan Should Cover
- ✓Closed-cell foam on metal roof and exterior walls
- ✓Separate plans for living space and attached shop
- ✓Sealing at doors, windows, eaves and the slab edge
- ✓Fresh-air ventilation for a tight home
- ✓Ignition or thermal barriers where code requires
- ✓Interior wall soundproofing between bedrooms and living areas
Best Insulation for a Barndominium
Closed-cell spray foam is widely considered the best insulation for barndominiums because it bonds to metal, controls condensation and adds strength. Roof decks commonly get 3 to 4 inches and walls 2 to 3 inches in living areas.
Some owners use a hybrid approach, with a thinner layer of closed-cell foam on the metal followed by batt insulation or open-cell foam in framed interior walls. That can lower cost while keeping the condensation protection where it matters. Attached shops are often insulated more lightly than the living space.
