Humid weather can sometimes be the enemy of building materials, including insulation. High humidity climates create the perfect conditions for mold growth, which can devastate a home. When you’re considering what type of insulation is best for your home, protecting against moisture is key. 

Here are a few kinds of insulation that are best for humid regions.

Fiberglass Insulation

Fiberglass insulation is a good option for humid climates because it does not absorb moisture, and mold cannot feed off of it. This means mold is unlikely to spread throughout the insulation if moisture enters your attic or home. 

In addition, fiberglass is very flexible and can be used to fill in small spaces to keep humidity out of your attic. Fiberglass is a popular and cost-effective option for homeowners.

Spray Foam Insulation

Spray foam insulation is a good option for homeowners in humid climates because it is one of the most effective ways to create a complete seal in your attic. Absent other mitigation techniques, some types of insulation can leave your attic vulnerable to moisture from the outside. 

Spray foam insulation gets in every crack and crevice, keeping all of the outdoor moisture from creeping into your home.

Mineral Wool

Even if your attic is perfectly sealed in humid climates, it is still a good idea to use moisture-resistant insulation, like mineral wool. 

Unlike other types of insulation that can absorb moisture and become damaged or moldy, mineral wool tends to dry out rather than absorb moisture. Even if mineral wool becomes damp or wet, it doesn’t tend to stay that way and will protect your home from mold growth.

If you live in a humid climate, it is important to choose the right insulation for your home. Work with your insulation contractor to ensure that your attic is insulated properly and that it will protect your home from moisture for the long term.
