Attic Insulation

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.
