When considering the different types of insulation, people are often drawn toward fiberglass insulation because it is common and effective. But fiberglass has a lot of disadvantages. For one, it requires a vapor barrier to block out moisture, and it does not create a good seal between wall and ceiling space. Additionally, fiberglass can be detrimental to lung health. Lastly, fiberglass breaks down, and its efficacy decreases over time. There are multiple alternatives to fiberglass insulation, and one great alternative is spray foam insulation.
Spray foam insulation is created from two materials that, when mixed, create a polyurethane foam that has good coverage and is highly effective. There are multiple types of spray foam insulation, but generally speaking, they are better than other types of insulation because of their application and qualities.
- Prevents Moisture and Mold:
One of the greatest advantages to spray foam insulation is the reduction of moisture, which helps to prevent mold growth. Air penetrating the attic, walls, or crawlspaces of a home can lead to moisture buildup. When temperatures cool, that moisture condenses into water and a habitat that is conducive to mold growth. With spray foam insulation, there is a minimal risk for mold growth because the moisture cannot get in to begin with. There are no cracks or areas where insulation could not fit, and the insulation expands to fill every space.
- Highest R-value
There are multiple R-values available for most insulation types, but one of the highest available R-values is in spray foam insulation. The only higher R-values are in vacuum insulated panels, silica aerogel, and polyurethane rigid panels.
- Energy Savings
Because of the high R-value, spray foam insulation is very energy efficient. This can make you save 30 to 50 percent on your electricity bill. Depending on where you live, spray foam insulation may be an expensive option, but it will pay off in the end.
Lastly, spray foam insulation does not break down like fiberglass insulation. This means you may not have to replace it. The way it sets up makes it last for many decades, probably longer than you’ll live in the home even if you don’t plan on moving.
Spray foam insulation is not a new product, but it is one that has not been used by most homeowners because of the popularity of fiberglass insulation. One of the biggest benefits to spray foam insulation is that is prevents moisture to the home. Keeping out moisture decreases the ability of mold to grow, which keeps your home a healthy environment.
