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.
