Open-cell spray foam insulation is cheaper, expands more, and allows more air circulation than closed-cell spray foam. Closed-cell is more expensive, doesn’t expand as much, and seals well enough to act as a vapor barrier. It also has about twice the R-value of open-cell spray foam insulation.
How long does closed cell foam last?
80 years
