Spray foam insulation is one of the most effective ways to improve energy efficiency, comfort, and durability in residential, commercial, and metal buildings. It expands on application, sealing cracks, gaps, and hard-to-reach areas to create an air-tight barrier that traditional insulation can’t match.

Open Cell Spray Foam

Open cell spray foam is a lightweight, flexible insulation that expands significantly to fill wall cavities and framing spaces. It is commonly installed at 3.5 inches (2×4 walls) or 5.5 inches (2×6 walls). Open cell provides excellent air sealing, sound reduction, and thermal performance, making it ideal for wood-frame homes, interior walls, attics, and residential applications where moisture resistance is not the primary concern.

Closed Cell Spray Foam

Closed cell spray foam is a dense, rigid insulation that delivers high performance in thinner applications. It is typically installed at 1 inch or 2 inches of thickness and offers a higher R-value per inch, along with a built-in vapor barrier. Closed cell adds structural strength and resists moisture, making it the best choice for metal buildings, commercial spaces, garages, shops, and areas exposed to humidity or extreme temperatures.

Key Differences & Best Uses

• Open Cell: Softer, thicker application, excellent air sealing and sound control, best for wood structures and residential interiors.

• Closed Cell: Thinner, stronger, moisture-resistant, higher R-value, best for metal buildings and demanding environments.
