When choosing insulation for your new home, you may be tempted to go with fiberglass over spray foam simply because it's cheaper. However, spray foam insulation is well worth the extra cost in the long run. Here's a look at some of spray foam insulation's major benefits.
Lower energy bills.
You'll pay more for spray foam insulation upfront, but it will likely save you money in the long run. Spray foam does a better job of reducing heat transfer. Since it seals to the structures it is sprayed onto, it does not allow air to leak through gaps. Both of these factors lead to lower heating and cooling bills and a more comfortable home.
Fewer problems with mold.
Fiberglass insulation can absorb moisture, and once that happens, it can easily develop mold and mildew. Moldy insulation is less effective at keeping your home comfortable, and it also puts you at risk for allergic reactions and health issues. Spray foam insulation is a dense, water-resistant foam. It's not like the soft foam you'd find in a cushion or stuffed animal. Water rolls off its surface, meaning that it does not hold onto moisture or become moldy. This makes spray foam a great choice especially if anyone in your home has allergies.
Fewer issues with rodents.
Rodents like to build nests in fiberglass insulation. They can rip it apart and move it around, nestling into it. Spray foam insulation does not tear up like this, and it's not soft material. Plus, since it seals to the walls and floors where it is sprayed, there won't be as many gaps for rodents to enter your home through.
No safety concerns with kids.
Fiberglass may not be the most dangerous material in the world, but it's certainly not something you want your kids getting into. The fibers can cause splinters and could cause serious damage to the eyes. Spray foam insulation is totally safe once it's cured. You don't have to be worried if your child touches it. They won't be able to pick it apart easily, and there are certainly no fibers for them to breathe in or get in their eyes. Though some consumers have expressed concern about poisonous gasses being released from spray foam, as long as the insulation is installed and allowed to cure properly, this should not be an issue. An insulation contractor, like one from Alaska Quality Insulators Inc, will tell you to stay out of the home for a period of time after the spray foam is installed. Once this period of time has passed, you don't have to worry.
