Open Cell
Spray Foam
The smart choice for interior applications. Excellent soundproofing, a complete airtight seal, and a cost-effective solution for residential and commercial projects.
What It Is
Open cell spray foam is a low-density polyurethane foam with cells that are intentionally left open. This structure allows the foam to expand dramatically on application - filling every gap, cavity, and irregular surface with a complete airtight seal.
It contains no formaldehyde, CFCs, or VOCs, making it one of the cleaner options on the market. Its softer, flexible structure also gives it superior soundproofing characteristics that rigid insulation simply can't match.
Key Benefits
- R-3.5 to R-3.7 per inch
- Superior soundproofing and noise reduction
- Expands to fill every gap and irregular cavity
- No formaldehyde, CFCs, or VOCs

Budget-conscious residential and commercial projects where interior air sealing, soundproofing, and thermal performance are the priority. The ideal choice for walls, attics, and anywhere noise control matters.
