Smart Comfort. Seamless Protection.
At East Coast Foam and Coating Supply, we proudly offer open cell spray foam insulation — a lightweight, highly expandable solution ideal for interior thermal and sound insulation applications. Known for its sponge-like structure and superior air-sealing capabilities, open cell foam fills every crevice, creating a continuous barrier that enhances comfort and efficiency.
What Makes Open Cell Foam Stand Out?
Open cell spray foam isn’t just insulation — it’s a performance upgrade for your building envelope. Its expansive application and breathable structure make it an ideal choice for contractors looking for reliable results and faster installations.
Key Benefits:
Air-Tight Performance
Creates a tight thermal seal, reducing energy loss through air leaks and making HVAC systems more effective.Built-In Sound Control
Its porous structure naturally reduces airborne sound transmission — perfect for noise-sensitive interiors.Ideal for Framing Cavities
Easily conforms to odd shapes, corners, and tight framing gaps, ensuring complete coverage without compression or settling.Environmentally Friendly Options
Many open cell foams are available with water-blown or low-GWP blowing agents, supporting greener building practices.Budget-Conscious Efficiency
Delivers excellent performance at a lower price point than closed cell foam — ideal for volume-driven projects and residential builds.
Best Use Cases
Open cell foam is an optimal choice for:
Residential attics and rooflines
Interior walls (especially for sound control)
Floor assemblies
New construction and retrofits
Low-moisture environments
Technical Overview
| Property | Value |
|---|---|
| R-Value | ~3.6 to 4.0 per inch |
| Density | ~0.5 lb/ft³ |
| Expansion | Up to 100x its liquid volume |
| Permeability | High (vapor permeable) |
| Application Temp | 60–100°F (ambient conditions) |
Note: Open cell foam is not a vapor barrier and should not be used where moisture intrusion is a concern without a separate vapor retarder.
Professional Tips for Installers
Apply in layers for better curing and control
Use thermal barriers (e.g., drywall) where required by code
Monitor substrate temperatures for optimal adhesion
Ensure proper ventilation during curing
