Spray Foam vs Fiberglass for Pole Barns: Which Is Better in Tulsa?

Closed-cell spray foam is better for most existing pole barns around Tulsa because it bonds to the metal, stops condensation and seals air leaks. Fiberglass blanket costs less and is a good choice for new construction, as long as the facing is sealed at every seam.

Side-by-Side

• Cost: spray foam about $2.00 to $4.00 per square foot at 2 inches; faced fiberglass about $1.00 to $2.00 per square foot during construction
• Condensation: spray foam bonds to the metal and stops it; fiberglass depends on a perfectly sealed facing
• Air sealing: spray foam seals gaps; fiberglass does not
• Existing buildings: spray foam is sprayed from inside; fiberglass usually means removing panels
• Pests: mice and birds rarely nest in cured closed-cell foam; fiberglass is a common nesting spot

When Fiberglass Makes Sense

If your barn is not built yet, faced metal building blanket installed with the panels is the lowest-cost way to insulate. It works well in dry storage buildings and when a liner is planned.

When Spray Foam Makes Sense

If your barn is already standing, drips, has torn insulation, or will be heated, closed-cell spray foam is usually the better value. It is also the common choice for barndominiums.

Oklahoma Weather Matters

Tulsa's humid summers and cold snaps mean metal buildings spend a lot of time near the dew point, which is why condensation control matters so much here. See pole barn condensation control and fiberglass pole barn insulation.
