Having any amount of excess moisture in your home can be extremely dangerous. Mold can grow exponentially in just a matter of days. Once the moisture has settled, it can be a big undertaking to rectify the situation. If you’re applying spray foam insulation to your home, you may be wondering if it will stop water.

Where Does the Water Come From?
Moisture typically comes from the exterior walls of your home. While you may see it on an internal level, you want to stop the moisture from coming inside. While you may find moisture on an exterior surface, it’s going to be stopped by the insulation.

Do Other Forms of Insulation Stop Moisture?
Spray foam insulation is the only type of insulation that will stop the moisture outside from coming in. Fiberglass insulation and other products don’t provide enough of a barrier. You’ll have gaps that will allow dampness to come inside. Many of these other insulations can even absorb moisture. Holding that moisture in place can actually promote mold growth rather than promoting evaporation.

Other Benefits
In addition to locking out moisture, spray foam insulation can also provide a good sound barrier from the outside. There is an open cell structure in the foam that prevents noise from passing through it. Many homeowners also notice that they have less pests in their home once the product has been applied. You’re essentially sealing all those cracks and gaps that are perfect spots for unwanted house guests to get through.

Your average homeowner is starting to move away from the more traditionally used insulation options. Spray foam insulation works much better to seal out moisture. The other benefits that come along with proper installation are really what seal the deal. If you want a safe home that is free of moisture issues, then spray foam insulation is the way to go.
