What’s The Difference Between Blown-In and Batt Insulation?

Blown-In-Insulation2When it comes to installing insulation, you have some choices. This blog takes a look at the differences between blown-in and batt. The most obvious differences are the appearance and installation methods of each type. Blown-in insulation is typically made from small particles of fiberglass, cellulose or rock wool that are installed with an insulation blower. While Batt insulation is also made from fiberglass or rock wool, on the other hand, is sold in long pieces that are cut to fit the project, and the insulation may be backed with paper.

Comparing Insulation Types

Irregular shaped spaces, such as attics, benefit from blown-in insulation because the insulation fits around the existing features of the home. Batt insulation is more suited to open spaces, such as the space between wall studs. The type of blown-in insulation used, and its thickness, should be determined by a professional insulation installer. Rock wool insulation is recommended for areas where high heat is present, such as around fireplaces. Please note that neither batt insulation nor blown-in fiberglass work as an air barrier, and both types of insulation are prone to moisture. In areas where an air barrier is needed, high-density cellulose batt is more effective than fiberglass.

Cost and Ease of Installation

Both blown-in and batt insulation can be installed quickly and are comparable in cost. When considering the cost of insulation, homeowners should also consider how well the insulation works. Insulation with an adequate R-value, which refers to its ability to stop the transmission of heat, can reduce heating and cooling costs.
