The choice of house insulation depends on energy efficiency required and
insulation budget. Common types of insulation are batt insulation and blown in
insulation. Batt insulation can be made of fiberglass or a rock wool material.
Blown insulation is normally a cellulose or fiberglass material.
House Insulation Batts are precut fiberglass or rock wool insulation. These
batts can either be faced or unfaced. Faced batts have paper or foil on one
side of the batt. Normally faced batts are used in the exterior walls and unfaced
in the interior walls. The batts can be used for insulation, sound proofing and
as a fire barrier.
Blown Insulation is a process in which loose insulation is blown into the attic
instead of using batts to produce a insulation blanket. Blown insulation is
normally a cellulose, fiberglass, or rock wool material. Cellulose insulation is a
form of blown in insulation. This insulation is normally blown in loose. Another
process adds a liquid adhesive and is blown in wet. The insulation has to be
allowed to dry before covering with drywall.
There are also some specialty types of insulation such as foam and an
adhesive type cellulose product. These products are sprayed on and provide
an air tight application.
