Spray Foam Insulation for Metal Buildings in Houston

Stop interior sweating, stabilize temperatures, and quiet the echo. Phantom Foam installs high-performance spray foam systems for shops, warehouses, barns, and barndominiums across Greater Houston—built to handle Texas heat, humidity, and daily use.

Condensation Control

Closed-cell foam breaks the thermal bridge on metal skins and helps stop interior “sweating.”

Energy Efficiency

Air seal + R-value = smaller HVAC load, steadier temps in big volumes.

Rigidity & Longevity

Foam adds stiffness to panels and roof decks; won’t sag like batts.

Noise Reduction

Cut echo and outside noise for more comfortable shops and buildouts.

Where Foam Performs Best in Metal Buildings

Roof Panels & Purlins

  • Closed-cell 1.5–2.5" typical; more for extreme loads
  • Breaks condensation cycles under roof metal
  • Helps quiet rain impact and sheet vibration

Wall Panels & Girts

  • Closed-cell 1.5–2" common; thicker for cold storage
  • Air seals panel laps, penetrations, and trims
  • Improves comfort for offices inside the shell

Barndominium Buildouts

  • Closed-cell on the shell; open-cell in interior walls/ceilings
  • Great acoustics + thermal performance
  • Ready for drywall/finishes after cure

Final specs depend on use-case (shop vs living space), ventilation, and code.

Open-Cell vs Closed-Cell for Metal Buildings

Open-Cell

  • Excellent sound dampening; thicker lifts
  • Interior partitions & ceilings in conditioned spaces
  • Not a vapor retarder—avoid directly on metal skins

Closed-Cell

  • High R/inch, adds rigidity, resists bulk moisture
  • Acts as a Class II vapor retarder at common thickness
  • Preferred on roof/wall metal panels and exterior shells

Typical Thickness & Details

  • Walls: Closed-cell 1.5–2" (higher for offices/cold rooms)
  • Roof: Closed-cell 2–3" depending on heat load & condensation risk
  • Conditioned Buildouts: Open-cell 5–7" in ceilings; 3–5" in interior partitions
  • Penetrations: Seal around fasteners, frames, mechanical/electrical

We meter moisture, review ventilation, and size foam lifts for proper cure.

Use Cases We Handle

Shops & Garages

Reduce heat gain and tool rust risk with proper vapor strategy.

Warehouses & DCs

Air sealing large volumes for steadier temps and quieter interiors.

Barndominiums

Shell with closed-cell; interiors with open-cell for comfort and acoustics.

Ag & Cold Storage

Thicker closed-cell assemblies to control moisture and temp swings.

Our Metal Building Foam Process

  1. Site Walk & Scope: inspect panels, fasteners, leaks, and condensation signs.
  2. Spec & Quote: closed/open-cell mix, thickness, phases, and access strategy.
  3. Prep & Protection: mask frames, doors, electrical; ensure ventilation.
  4. Install: even passes and lift timing for adhesion and cure.
  5. QA & Cleanup: edge sealing, touch-ups, and clean job site.

Metal Building Spray Foam — FAQ

Will foam stop my metal roof from sweating?

Closed-cell breaks the thermal bridge on metal and helps prevent interior condensation when properly specified.

Can I foam the underside of an existing roof?

Yes—after checking for leaks and prepping clean, dry surfaces for adhesion.

Is open-cell okay in metal buildings?

Use open-cell for interior partitions/ceilings in conditioned spaces. Use closed-cell on the metal shell.

How thick should I go?

Commonly 1.5–2" on walls and 2–3" on roofs. Cold storage or high-spec rooms may need more.

Will foam make the building quieter?

Yes—foam dampens rain impact, sheet vibration, and highway/neighbor noise.

How long does install take?

Small shops can be 1 day; larger warehouses or barndos may take multiple days depending on scope.
