What’s the Difference Between Blown-In Insulation & Blanket Insulation?
*Before any insulation job is started, there should be an inspection performed for areas with air leakage. These areas should be sealed prior to insulating your home.
Blanket Insulation is is the most commonly used insulation. It comes in the form of Batt Insulation and Roll Insulation. This type of insulation has long, interweaving fibers, most commonly made of cotton and fiberglass. They are pre-cut to fit in between your home’s studs and ceiling joists. Both cotton and fiberglass insulation are equally efficient.
The only downfall of batt or roll insulation is that it sometimes does not completely fill in the space in between some studs or joists due to the different structures of each home. Batt and Roll insulation also have to compete with electrical boxes, wires, plumbing, etc.
The main benefit of Blanket Insulation is that it is less costly than Blown-In Insulation.
Blown-in Insulation, also referred to as Loose Fill Insulation, tends to be more efficient because it is applied in much smaller pieces, which can reach spots that batt insulation simply cannot. Blown-In Insulation is usually done by a professional because it requires special equipment. There are 2 common types of blown-In Insulation-cellulose and fiberglass.
Cellulose – This form of Blown-In Insulation is made up of small pieces of newspaper or cardboard. It is sprayed with chemicals to make it fire, mold, and insect & rodent resistant.
Fiberglass – This form of Blown-In Insulation is made up of small particles of spun glass fibers.
The main benefit for Blown-In Insulation is that it is more efficient because it can reach and fill in spots that Blanket Insulation cannot.
