Important Facts About Spray Foam Insulation | Billy.com

Spray foam is one of the most popular insulation methods out there, and for good reason. If you need to insulate your home, then it’s a great choice. However, you should never make a decision about your living space without being informed. Let’s dive into some important facts about spray foam insulation.

There Are Two Types of Spray Foam

There are two types of spray foam insulation: open-cell and closed-cell. What does that mean? Let’s break down each term.

Open-Cell

First up, we have open-cell spray foam. This type features foam cells that aren’t completely closed, allowing for a more flexible, lightweight foam. It expands significantly and offers incredible thermal regulation, but not as much as closed-cell foam does.

Closed-Cell

Speaking of which, closed-cell foam features cells that are completely closed, producing a denser, even more energy-efficient insulation option. However, because it doesn’t expand as much as open-cell foam, it’s not as great at filling nooks and crannies.

It Improves HVAC Functionality

Spray foam insulation is basically a personal assistant for your HVAC system. By providing a perfectly sealed environment, the insulation can improve your HVAC’s efficiency by trapping the heated or cooled air it produces.

This means your HVAC system doesn’t have to work overtime, resulting in lower energy bills and a longer lifespan for your heating and cooling units.

It Protects Your Home’s Air

The only time spray foam hampers air quality is while it is being sprayed. Once applied and set, it protects your home’s air quality to the max!

Because of its tight seal, especially when it comes to closed-cell varieties, spray foam keeps out pollutants, allergens, and moisture. Furthermore, because it deters moisture, it also inhibits mold growth.

It Lasts a Lifetime

Even if your love life isn’t going so well, spray foam insulation is a guaranteed long-term relationship. Though time does have an effect on spray foam, it typically lasts between 80 and 100 years. So when we said it lasts a lifetime, we meant that literally.

It’s Mold-Proof

We already mentioned that spray foam reduces moisture in a home and therefore inhibits mold growth. But did you realize that the foam itself is mold-resistant? That’s because there’s nothing organic in spray foam, and therefore nothing for mold spores to live on.

Did these important facts about spray foam insulation teach you anything new? We hope you learned something useful and that you feel more confident and informed in your search for home insulation.
