What is open celled foam?
Similarly one may ask, does open cell foam absorb water?

Secondly, does open cell foam mold? According to Frank, moisture can be a concern if you construct a home and insulate it with open-cell spray foam. If closed cell is used, the moisture cannot make its way to the wood and present mold issues.
Besides, where is open cell spray foam used?
Open cell spray foam has a very high expansion rate, sometimes as much as 100 times over. This makes it an ideal option for homes because it gets in the nooks and crannies in attics, crawl spaces, and rim joists. Closed cell spray foam has very minimal expansion when applied.
