If you are planning on getting spray foam insulation, one of the options you will have is to use open cell foam insulation. In this insulation method, the small cells of the foam are not totally closed.

They are open, and as a result they allow air to fill all of the tiny pockets in the material. This makes the foam in this kind of insulation to be structurally weaker and less resistant compared to closed foam insulation.




Another thing to know about open cell foam insulation is that it requires an interior vapor retarder, for instance a layer of gypsum wallboard that has a finish of vapor-retarder paint.

This will be especially important if you are creating a cathedralized attic in a place that experiences very cold weather. It is however important to make sure that the vapor retarder paint is sprayed properly onto the foam insulation, otherwise it may end up being ineffective.




It usually has a density of approximately 0.5 lb per cubic foot. Its R value, or resistance to heat flow value, is about 3.5 or 3.6 per inch. This cell foam is permeable to moisture and impermeable to air.

Compared to closed cell foam, it uses significantly less material. This makes it very attractive from a resource-use standpoint. Many people prefer it over the closed cell foam because it is very easy to determine the source of leak if there is any.




Since it is not a vapor barrier, it allows water to run through it. It is also less dense and softer. It can contract and expand easily with the decking. It is also very beneficial to the environment.

This is because 20 percent of it is completely made out of renewable agricultural products. Some of the products include sugar beets, corn and sugarcane. This allows the insulation to be less harmful to use and allows less waste for the products.



The most important thing about the open cell foam insulation is how well it holds heat inside the building. Since it is denser compared to other traditional insulation methods, you can save a lot of money on air and heating bills when using it.

And because it is sprayed on, it completely covers where it is applied. Using it lowers the carbon footprint in your home since it uses less energy, something which helps to keep the environment healthy.



Unlike other insulation products that are prone to mold and mildew over time especially when there is water involved, open cell foam insulation does not have this problem. This is because it has special anti-microbial ingredients that usually prevent any buildup of mold or mildew.

This in turn makes the quality inside your house to be healthier, and it can also prevent mold from building up on the back side of the walls of your building.



This insulation is also meant to last. Once you apply it, it will last as long the structure will last.
