The benefits of open-cell spray foam
As mentioned, open-cell foaming insulation is best suited for interior applications, offering an array of advantages of traditional fibrous insulation materials. Benefits of open-cell foam insulation include:
- Allows for bi-directional drying
- Can accommodate long-term creep and seasonal movement
- Can be installed at a significantly lower cost and target the same specified R-value*
- Is not considered a food source for mold
- Provides sound dampening qualities, ideal for use media or theater rooms
- Lower installed cost, per square foot
The benefits of closed-cell insulation foam
While open-cell foamed insulation has many benefits over traditional insulation types, closed-cell sprayed-in insulation goes beyond to offer additional advantages. Although closed-cell sprayed insulation foam has a higher per board foot cost, there are benefits that the material offers including:
- Ability to reject bulk water (closed-cell foam insulation is recognized as a flood resistant material by FEMA(link is external))
- Can be applied at very low temperatures (as low as 5°F)
- Adds wall racking strength as well as impact resistance
- Higher R-value* per inch – easier to accommodate high R-value* requirements in narrow spaces
- Higher tensile and bond strength
