The open cell nature of foam means you are not resisted by the seams, but it is still very good at sealing - letting moisture vapor pass through.
Spray foam is soft and spongy just before it sets. It's similar to diffuse-and-firm closed-cell insulation but this type allows water vapor to pass through it.
Spray foam insulation is a very lightweight option and it doesn't affect the structural integrity of the building. This is a good choice if your company is looking to save money or go green. You, also get great soundproofing from open-cell foam insulation.
First, take the components of open-cell foam and mix them. It can fill up to 4 times more area than closed-cell foam thanks to its aerosol-like properties.
Although open-cell spray foam has a lower R-value per inch at 3.5-4, it also costs less at a much lower price.
Both foam products are trying to be greener, with some manufacturers using natural materials like soy oil at low percentages.
Open-cell foam typically uses water, which does not increase global warming. Closed-cell foams typically have chemicals that are more damaging to the environment.
