Air leakages due to compromised insulation account for 25% to 40% of your heating and cooling usage. On the other hand, investing in an efficient home insulation can help you save between 10% and 20% on energy bills. Today, WMGB Home Improvement talks about blown-in insulation and how it can help manage energy loss in your home.

Home Insulation 101: The Basics of Blown-In Insulation

Why Choose Blown-In Insulation?

While fiberglass batts are among the most commonly used materials for insulation, they have major disadvantages that a blown-in insulation can address. Fiberglass insulation rolls come in 16- or 24-inch precut strips, greatly limiting their ability to cover oddly shaped nooks and crannies that are characteristic of attics where insulation is necessary. Blown-in insulation, also called loose-fill insulation, offers the perfect solution to this particular coverage issue. On top of that, loose-fill insulation installation is faster and more convenient compared to the tedious process of carrying unfaced fiberglass insulation rolls into your attic.

Materials Used

Blown-in insulation is composed of various loose materials with high R-value. R-value refers to the capacity of a material to resist heat; a higher R-value results in a better insulating capacity. Blown-in insulation has an R-value of 3.2 to 3.8 per inch and typically uses Styrofoam pellets or shreds of loose fiberglass. However, cellulose material is the most commonly used material for blown-in applications. Cellulose is resistant to fire and molds due to a combination of boric acid and other substances. The insulating material itself is made from a variety of wood-based elements, such as recycled newspapers and cardboard, making it a green product.

Application

Blown-in applications require the use of a mechanical blower, which mixes the cellulose with air. The mixture is then expelled through a hose. Blown-in insulation is ideal for closed-up walls and attic with cramped, hard-to-reach spaces. It can be applied over existing fiberglass insulation for an enhanced R-value.
