Many homeowners are unaware of the importance of adequate attic insulation. Inadequate insulation can be responsible for drafts, high utility bills and unexplained heat loss. Here is some basic information about attic insulation to help you understand how it can benefit your home.
Rolls and batts are generally made from rock wool or fiberglass. Their flexibility makes them practical for placing between attic or floor joists and between wall studs.
Loose-fill insulation is a type of attic insulation made from fiber pellets or strands created out of fiberglass, rock wool or cellulose. Specialized pneumatic equipment makes it relatively easy for technicians to blow the loose insulation into oddly-shaped or hard to reach spaces.
Rigid foam insulation is more expensive than loose-fill, roll or batt style insulation, but it works well to insulate exterior walls or along openings, such as attic doors. It is twice as effective as the same amount of other kinds of insulation.
Foam-in-place insulation is practical for out of the way locations and small spaces. The chemicals come out of pressurized spray cans to fill openings in walls and window or door frames, preventing heat loss and cold drafts.
Measure the insulation. You want your attic to have a minimum of 11 inches of rock wool or fiberglass insulation or eight inches of cellulose insulation.
You should not be feeling cold drafts in the winter or feel overheated in the summer.
Your utility bills should not be excessively high compared to other homes in your area.
