What Is Spray Foam Insulation?

Spray foam is a two-component mixture applied as a liquid that quickly expands into a solid foam. It fills cracks, gaps, and hard-to-reach spaces—creating an airtight barrier that dramatically reduces heat loss and air leakage.

We offer both:

  • Closed-cell spray foam – High R-value, vapor barrier, structural strength

  • Open-cell spray foam – Excellent air sealing, sound absorption, air barrier, and sound retention.

Benefits of Spray Foam Insulation

  • Superior Energy Efficiency
    Spray foam can cut heating and cooling costs by creating a continuous air seal.
  • Air & Moisture Barrier
    Prevents drafts, humidity, and water intrusion—perfect for steel buildings and coastal climates.
  • Long-Lasting Performance
    Unlike fiberglass or cellulose, spray foam doesn’t sag, settle, or degrade over time.
  • Mold and Pest Resistant
    Closed-cell spray foam resists mold growth and deters rodents and insects from nesting.
  • Noise Reduction
    Open-cell spray foam helps reduce sound transmission between walls and floors.
  • ✅ Boosts Structural Strength
    Closed-cell foam adds rigidity to metal walls and roofing panels.
