The best way to seal and insulate your home is also one of the most fascinating to watch.
Spray foam insulation can be the perfect fit for your home – literally. The innovative process adds insulation to every nook and cranny of a house, making it an ideal solution for sealing buildings and keeping you comfortable. Don’t get overwhelmed with the process – when installed by a certified contractor, spray-foam insulation is one of the best ways to insulate your home.
What Is Spray Foam Insulation?
From batts to blown-in insulation, there are several ways to insulate your home – but the best of the best is spray foam insulation. Spray foam works by combining two fluids and spraying them like water from a hose. When the liquids mix, they expand into a solid in a chemical process that is surprisingly fun and interesting to watch.
Two of a Kind
There are two types of spray foam insulation, open cell and closed cell. The difference between the two quickly becomes technical, but simply put: open cell foam is lighter, closed cell foam is denser. Closed cell foam will cost more but offers greater moisture protection and insulating power. Your certified contractor can advise you on the best spray foam insulation for your project.
For more information on the chemistry behind the two types of foams, check out this guide.
CertainTeed offers both types of spray foam: Certaspray Open Cell Foam and CertaSpray Closed Cell Foam. And spray foam insulation can be used with other types of insulation for even greater protection. This is called a hybrid insulation system and can be a cost effective way to achieve improved performance. For instance, you spray and seal the wall cavity with a layer of spray foam, then fill the rest in with batt or blown-in fiber glass insulation, it’s like zipping up a winter coat over a nice warm sweater. You can learn more about hybrid insulation in this article.
Benefits of Foam
Small gaps in insulation can lead to cold, drafty rooms and higher heating bills. Spray foam can fit into any area, block any hole and prevent cold air from ruining your home’s comfort and your wallet. Spray foam insulation offers the highest R-value when compared to other products. R-value refers to how much heat is blocked by the material.
Imagine coloring in a circle; crayons may do a wonderful job, but if you want to make sure every part of the circle is colored, you use paint because the liquid covers every inch of the circle. Since it’s applied like paint, spray foam offers greater coverage for every area of an attic, between wall studs, and anywhere insulation is needed. Hard to reach corners and crawl spaces can’t hide from spray foam.
Not only will spray foam keep the heat inside your home, it keeps noises out. Spray foam works as an acoustic barrier, preventing unwanted noise from seeping into your house and your ears.
Can You Install It Yourself?
Watching the foam expand into the joists looks fun, but this is NOT a project you can tackle yourself. It’s very dangerous to breathe in the chemicals during the application process which is why proper training, precautions, and personal protective equipment (PPE) must be used. Besides potentially doing harm to yourself, if you don’t know what you’re doing, you likely would not install the product properly, leaving your home under or incorrectly insulated. To ensure proper insulation and safety, spray-foam insulation should only be installed by a certified contractor. Click here to find a contractor near you.
