What is better open or closed cell spray foam insulation?
Both open cell and closed cell spray foam insulation have their positives and negatives. However, most spray foam insulation on new home construction and existing homes uses closed cell spray foam. Closed cell spray foam is the most desired for its heavy denseness, with the less dense open cell filling in some gaps. Closed cell spray foam insulation has more benefits than open cell, so it is used more often. Closed cell spray foam is very dense, which makes it have high heat flow resistance, or R-Value. This makes it so the temperature within the home is maintained well. Another closed cell spray foam insulation benefit is that because of its high density, it is water resistant. If you live in a moist, humid area, and need new construction foam insulation, closed cell spray foam will reduce the amount of humid air that gets into your home, decreasing the chance of mold damage. Lastly, there are structural benefits of spray foam insulation. Since the insulation molds and drys on the walls, it strengthens it. Open cell spray foam is used in hard to reach areas, but is not recommended for all around the house use like closed cell spray foam. This is because open cell is not as dense or waterproof as closed cell spray foam, so it should only be used when it's necessary for there are less structural benefits of the spray foam insulation. Open cell foam is great in the fact that it expands when it sprayed and can therefore be sprayed in hard to reach areas with nooks and crannies. Open cell foam first expands and then molds, while closed cell mols does not have the ability to expand. This is why open cell works so great is small, hard to reach areas with crevices, for it can be sprayed in one area, and still reach another.

Do I need to install a vapor barrier with spray insulation foam?
When considering different crawl space insulation, it is important to know all the rules and codes that go along with each option. In regards to the installation of open cell foam insulation, a vapor barrier is required. This is because the heat flow resistance (R-Value) is low, so there is a lot of moisture that could be trapped in the building. Outside, mold is essential to our ecosystem for it’s a great decomposer of wood, fruits and much more. Therefore, mold on the inside your home does the same thing. However, the decomposition of the wood inside your home could lead to serious problems. Mold also emits spores that can lead to serious health issues, and a musty smell. Since open cell spray foam isn’t great at keeping the moisture out, a vapor barrier must be added as an aid. On the other hand, closed cell spray foam doesn’t require a vapor barrier. This is because it has a very high R-Value, and doesn’t need the extra layer of protection. No matter which one you choose, there are many spray foam insulation benefits associated with each one.
