How much does it cost to spray foam a metal workshop?

A 30x40 workshop with about 2 inches of closed-cell foam on walls and roof commonly costs about $5,500 to $11,000. A 24x24 garage typically runs about $3,000 to $6,000.

Does spray foam stop condensation in metal buildings?

Yes. Closed-cell foam keeps the steel above the dew point and seals the panel seams, which stops dripping at the source.

Is 1 inch of closed-cell foam enough?

For an unheated building, often yes. Heated or cooled workshops usually need 1.5 to 3 inches.

Should I run electrical before spray foam?

Yes. Run wiring, outlets and lighting first, because closed-cell foam makes later changes harder.

Do mice nest in spray foam?

Rarely. Unlike fiberglass, foam leaves no soft voids for nesting, though doors and base trim still need sealing.

How long does a workshop take?

Most garages and workshops take one to two days.

Metal Workshop Spray Foam Insulation

Metal workshops and detached garages are common on larger lots around Jenks, especially south and west of town, along with storage buildings and small commercial shops. Bare steel heats up quickly in the summer sun and cools fast at night, which is exactly what creates condensation.

When warm, humid air meets cold metal panels, water forms and drips onto tools, vehicles and floors. Fiberglass blankets slow it down until the facing tears, and then condensation forms right at the damaged seams. Rust and mildew follow.

Closed-cell spray foam bonds to the steel, seals every lap and fastener, and keeps the panels warm enough that condensation stops. We give every building a free site visit and a written plan with foam thickness and area.

Jenks tip

Before insulating a workshop, decide where outlets, lights and any mini split will go. Wiring should be run before closed-cell foam is applied.

Signs Your Metal Building Needs Foam

✓Dripping roof panels on cool mornings
✓Rust on tools, fasteners or purlins
✓A shop that is too hot to use in summer
✓Torn or sagging blanket insulation
✓Plans to heat or cool the building
✓Dust and wind through panel seams

How Much Foam Does a Workshop Need?

About 1 inch of closed-cell foam on the roof and walls usually stops condensation in an unheated building at the lowest cost.

For a heated and cooled workshop, 1.5 to 3 inches of closed-cell foam, roughly R-10 to R-20, is common. Many owners put more foam on the roof than the walls. Open-cell foam is generally not used directly on metal because it absorbs moisture.
