Closed-Cell Spray Foam
A dense, rigid foam that delivers the highest R-value per inch and resists water. It adds stiffness to the structure and stands up to ground moisture, which makes it the standard for crawl spaces, rim joists, and tight rafter bays.
Why homeowners choose it
- The highest R-value per inch, in a thin profile
- Resists water and adds structural rigidity
- Specified where moisture and space are both tight
