Metal building insulation

Metal Building Insulation

Bare metal sweats. When warm humid air meets a cool metal roof or wall, water condenses and drips on whatever is inside. Closed cell spray foam bonds to the metal, seals the seams and stops the condensation at the surface.

Why closed cell for metal

  • Bonds directly to the panel, so there is no air gap for moisture to collect in
  • Acts as a vapor barrier at the right thickness
  • Seals lap seams and fastener holes
  • Adds rigidity and can quiet rain noise on the roof

Planning a new metal building?

Foam goes on fastest before the interior is built out. If your building is on order, tell us the delivery date and we will schedule around it.
