Blown-in Insulation: A Wise Choice for Attic & Wall Insulation
Blown-in insulation, also known as blown insulation,
is especially popular for upgrading attic insulation levels. It's faster than rolling out fiberglass batt insulation, and the resulting blanket of additional insulation usually provides more thorough and more uniform coverage than installers can achieve with fiberglass batts.
Another benefit for blown-in insulation is that you don't need to move in and out of the house to bring fiberglass batts into the attic. Instead, a single installer can set up in the attic and usually stay there until the installation is completed.
There are two basic types of blown-in insulation available: fiberglass and cellulose. The cellulose blown into attics is sometimes called "loose-fill" cellulose.
Blown-in insulation can be installed either in new constructions or over existing attic insulation, as long as the existing insulation is in good condition.
Sealing air leakage before installing attic insulation
BEFORE installing attic insulation, it's critical to seal energy-wasting air leaks between the attic space and the living space below. Insulation slows heat transfer, but will not stop conditioned air from leaking into the attic; that's why air sealing is always done along with an insulation upgrade. Dr. Energy Saver's skilled contractors have the know-how to find and seal air leaks using a variety of materials and techniques.
