Open Cell Vs. Closed Cell Spray Foam Insulation
| CLOSED-CELL | OPEN-CELL |
| Highest insulating “R-Value” per inch (>6.0) | Good insulation value (R=3.5) |
| Low vapor permeability | Higher vapor permeability, but controlled |
| Air barrier | Air barrier at full wall thickness |
| Increases wall strength | |
| – Resists water (is a WRB “water Resistive Barrier”) | |
| Absorbs sound, especially bass tones | Best sound absorption in normal noise frequency ranges |
| Economical Yield | |
| Approved by FEMA |
