Does spray foam act as a water barrier?
Open-cell spray foam insulation is not completely water-proof and will allow moisture to pass through it. As such, it will not form a sufficient vapor barrier, and you may need to have one installed depending on the location of the insulation and the climate of your area.

It is 98% closed cell resulting in an R-factor of 7.7, a low moisture absorption rate and excellent compressive strength.
Does rain damage spray foam insulation?
Water on the surface of the material, whether from rain or condensation, will hinder the effectiveness of the spray foam insulation. It will essentially prevent it from sticking properly. Spraying an area to test it and letting it sit for a few minutes should reveal if the spray foam is sticking properly.
How Long Does Spray Foam Take to Dry?
Does spray foam hold moisture? In a way, yes, because it has to have time to dry out.
How does open cell spray foam work?
So, how does this apply to open cell spray foam? Open cell spray foam is also a porous material. This composition helps the water pass through it and any moisture left over will evaporate. So, how long will it take for the spray foam to dry out?
Does spray foam absorb water?

Why does water move through concrete?
The water doesn’t just sit on the surface of the concrete, it actually moves through it because it is a porous material. This means there are tiny pockets inside the concrete, so when water comes in contact with it those little tiny pockets get filled up.
Does cellulose insulation help mold?
Fiberglass and cellulose insulation will retain that moisture and then allow for the growth of mold and mildew. That retained moisture and mold can cause problems as a homeowner tries to dry everything out to assess the damage.
Do you have to replace foam in a flood?

Is spray foam waterproof?
Whether your spray foam insulation is waterproof depends on the type of material you use. In short, closed cell spray foam is waterproof while open cell spray foam is not. This is because closed cell spray foam insulation is a denser material, while open cell spray foam is lighter and expands more. This is useful for filling large areas or insulating corners and crannies, but it doesn’t offer as much protection as its closed cell counterpart. Closed cell insulation, on the other hand, offers stronger resistance to the elements—including water.
Does water damage insulation?
Water can also destroy the insulation itself. When water seeps into your insulation material, it replaces the air that was providing better insulation for your home. Water conducts heat better than air does, which means damp insulation allows warm air to seep in or out of your home. Water can also cause your insulation to deteriorate over time. All in all, waterproof insulation is the key to better energy efficiency and a dry, healthy home.
