Closed-Cell Spray Foam
Dense spray foam combining strong thermal performance, air sealing, and moisture resistance.
What to understand
Start with the assembly, not a product label.
Material selection, substrate condition, access, and the surrounding assembly are reviewed together rather than treating closed-cell foam as a default answer.
- Selected attics and crawl spaces
- Walls and assemblies with limited cavity depth
- Projects where moisture-resistant characteristics are part of the discussion

Questions about closed-cell spray foam.
What is closed-cell spray foam?
It is a dense spray-applied insulation that can combine thermal insulation, air sealing, and moisture-resistant characteristics at the specified thickness.
Is it right for every attic or crawl space?
No. Existing conditions, moisture, code requirements, and the project goal should be evaluated first.
Why does the installation approach matter?
Product selection, surface preparation, application conditions, and the planned thickness all affect the finished system.
