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 |
