If you're shopping for home insulation, you're going to run into several different types and methods of installation. From blown-in insulation to spray foam insulation to roll batts, figuring out what type of insulation is best for your home can be confusing.
To help make your decision a little easier, today's blog post is a comparison between two of the most common types of insulation for your house: fiberglass and cellulose.
Fiberglass and cellulose insulation are usually both blown-in for easy installation. They are loose-fill, meaning they're made of small particles. Loose-fill insulation is advantageous because it can easily fit around obstacles like vents and supports. The small particles help trap air and keep your home well-insulated.
Fiberglass and cellulose do have some important differences. The first to consider is settling. Blown-in fiberglass insulation, like the AttiCat system, will not settle over time. Cellulose insulation, however, can settle up to 20%. When cellulose settles, it can lose a significant amount of its R-Value. Cellulose is also heavier than fiberglass, meaning some areas of a home may end up under-insulated due to weight restrictions.
Fiberglass insulation is made out of sand, recycled bottles, and is essentially glass. That means it is naturally fire retardant. Cellulose, on the other hand, is largely made of newspaper and must be sprayed with fire retardant chemicals. These chemicals can be harmful to your health and will disappear as much as 28% in the first two years, leaving your home more at risk of fire.
Blown in insulation is one of the best ways to insulate your home. In areas like Denver, Cheyenne and Colorado Springs, having a well-insulated home is important! When you consider adding insulation to your home, remember that fiberglass has the edge over cellulose when it comes to loose fill insulation.
