The Benefits of Honeyfoam Open Cell

Understanding the Difference: Open Cell vs. Closed Cell
Choosing the right kit depends on your specific project goals:
.
- Open Cell (R-3.7): Best for interior walls, soundproofing between rooms, and attics where moisture management is handled by other barriers.
- Closed Cell (R-6.2): Best for exterior walls, crawl spaces, and any area requiring a high-density moisture and vapor barrier.
