How It Works
Home heating and cooling takes a huge amount of
energy - usually more than any other home energy consumer. Attics can get
extremely hot under the blaring sun and frigidly cold with the winter breeze
flowing through. These extreme temperatures will naturally flow through your
home. That means you can dramatically lower your energy consumption by properly
sealing and insulating your attic.
Types and Environmental Impact
Most attic insulation is either
blanket (batts and rolls) or loose fill. Batts are fitted between studs, joists
and beams. This method works best for stud and joist spacing that is relatively
free from obstructions. Loose fill is generally cellulose, fiberglass, mineral
or wool and is good for adding to existing finished areas. It is also
appropriate for irregularly shaped areas and for working around obstructions.
An insulation’s resistance to heat flow is measured in thermal resistance or
“R-value.” The higher the value, the greater the insulating power. Properly
insulating and air sealing your attic will help reduce your energy usage and
decrease your carbon footprint. Attics are easy to reach (compared to the
insides of your walls) and save you the most money when insulated.
