Spray foam insulation, more specifically spray polyurethane, is an insulation option that provides several unique benefits. The reason it is called “spray foam” is because that is how it is installed. However, if you are considering this for your home, getting to know some of the benefits it offers can help you make the right decision. Keep reading to learn what those benefits are. 

High R-Value 

Per inch, spray foam polyurethane offers one of the highest R-values compared to any other insulation option. It has an R-value of four or five per square inch, and blown fiberglass only has an R-value of two or three. What this means is that spray foam is much more efficient. Optimizing the R-value requires you to add fiberglass batt insulation, too. This is going to create a superior barrier between the inside and outside of your home (or any other structure).

Air Sealing 

When you invest in a home energy audit, one of the first things you will likely discover is that you need air sealing. Since spray foam will expand where it lands, it offers tremendous air sealing abilities. It can close the gaps where pests, air, and moisture may make it into your home. 

Fire Retardant 

Something that many people do not realize is that spray foam insulation may actually slow down the spread of fire and flames. It is classified as a class one fire retardant. This means that it not only helps to keep your home comfortable but safe, as well. 

Prevent Condensation

There are two types of spray foam insulation that you can choose from – open cell and closed cell. The closed-cell option is a denser barrier that keeps water and air vapor out. With open-cell, it never closes completely, which means it has a more sponge-like quality. Because of the air sealing qualities and chemical makeup, closed-cell spray foam will help to prevent condensation, which may lead to mold growth. 

Outdoor Use 

The closed-cell spray foam is also able to be used outside. When you spray it beneath your roof or in concrete gaps, it will effectively seal anything while repelling moisture. Unlike the batt insulation, spray foam will be able to stand up to even the most extreme elements. 

Sound Proofing 

Not only is spray foam a moisture and air barrier, but it can also add sound-proofing benefits to the walls in your home. Your interior walls represent a great place to install open-cell foam, which is going to keep sounds in one room from traveling to others. 

If you are interested in having spray foam installed in your home, make sure to reach out to the professionals. They will be able to determine the right type of spray foam for your needs and provide professional installation. This is going to ensure that you get all the benefits mentioned here and more. Being informed is the best way to know why this insulation is best.
