Batt insulation is the most common form of home insulation, known as ‘batt and roll’ or ‘blanket’ insulation. Batt Insulation is typically stored in rolls, generally made of fiberglass and is the least expensive way to insulate a home and very easy to install.
Batt insulation is comprised of large pieces of insulation that hold together because they’re made of long, interweaving fibers with adhesive binders.
Batt Insulation is one of the most common products used to insulate walls, ceilings and attics as well as basements and crawl spaces and is generally manufactured from fiberglass, but can also be made from cotton or stone wool.
Batt Insulation has several advantages. Because contractors can install the product relatively quickly, it is one of the least expensive ways to insulate your home. When compared to other types of insulation, the fiberglass batt insulation generally has the lowest installed price.
Faced or Un-faced Batt Insulation?
Faced batt insulation is manufactured with a paper facing which serves as a moisture barrier; it generally has tabs used to hold the insulation in place.
Un-faced batt insulation is fiberglass only and is used where no moisture barrier is needed. Un-faced batt insulation is typically used in a crawl space using twine to secure it and keep it from falling on the ground. Un-faced batt insulation can also be used on exterior walls when a moisture barrier is used on the heated side of the wall.
