We Spray Your Building
Our certified crew applies 2" of closed cell spray foam to your walls, roof deck, and gable ends — typically in one day.
Enjoy the Results
Lower energy bills, no more condensation, and a quieter, more comfortable building — guaranteed.
Why 2" Closed Cell Foam?
The gold standard for metal building insulation — superior performance, long-lasting results.
Highest R-Value
2" of closed cell foam delivers R-13+, outperforming fiberglass batts at the same thickness.
Vapor Barrier
Acts as a Class II vapor retarder, protecting your metal building from condensation and rust.
Air Sealing
Seals every gap, crack, and penetration — eliminating drafts and dramatically reducing energy bills.
Structural Strength
Adds racking strength to metal panels, increasing the rigidity of your building envelope.
Noise Reduction
Dramatically reduces rain and wind noise — a common complaint with uninsulated metal buildings.
Long-Lasting
Closed cell foam doesn't sag, settle, or absorb moisture. It's a permanent, one-time investment.

Real metal buildings insulated by the Green Factor team.
