Why Barndominiums Need Closed-Cell Foam

A barndominium is a metal building that people live in. Bare metal panels swing hot and cold fast, and warm indoor air meeting a cold steel panel turns into condensation, rust and wet insulation. Batts and blankets leave gaps at every girt and purlin, so the problem comes back.

Closed-cell spray foam bonds directly to the metal skin and fills around the framing. It insulates, seals air leaks and keeps the inside of the panel warm enough that moisture does not form on it. That is why it is the go-to insulation for barndominiums.

Barndominiums and metal buildings are our main focus. We insulate the whole shell: walls, roof and the shop side if your build has one.

  • Bonds straight to metal panels, no gaps at the framing
  • Keeps panels above the dew point, so condensation stops
  • Air-seals the shell for steady indoor temperatures
  • Covers walls and roof deck in one system
  • Works for the living space and the attached shop

Frequently Asked Questions

Is closed-cell or open-cell foam better for a barndominium?

Closed-cell. It bonds to metal, adds rigidity and controls moisture on the panels. Open-cell is lighter and cheaper but lets moisture through, which is a problem against cold steel.

How thick should the foam be in a barndominium?

Living space needs more depth than a shop; homes are usually insulated much deeper than the roughly 2 inches common in shops. We recommend a thickness for your walls and roof at the estimate.

How is barndominium spray foam priced?

Spray foam is priced by the board foot: one inch thick over one square foot. Your price depends on the square footage of walls and roof you want covered and the thickness. Shops and garages usually get about 2 inches; homes need more. We give a ballpark from your measurements and confirm the final price after an on-site check.

Can you insulate the shop side and the living side?

Yes. Many barndominiums have both, and we can spray each to the thickness that makes sense for how it is used.
