Attic Insulation

Attic InsulationAttic insulation plays an important role in keeping the temperature of your home at a comfortable level year-round while reducing your energy costs. A properly insulated attic helps prevent the transfer of heat between your attic and your living areas. In the winter, it helps keep the air that you are paying to heat from rising into the attic. In the summer, insulation helps prevent the heat accumulated in the attic from leaking into your air-conditioned areas.

A properly installed attic insulation helps prevent the transfer of heat between your attic and your living areas.

Many homes, however, do not have too little insulation or insulation that has inconsistent depth. One common mistake that many homeowners make is misjudging the amount of insulation that an attic needs. As a rule of thumb, if the floor joists in the attic can be seen, more insulation is needed. The thickness required depends on a variety of factors, including the type of heating and cooling system used, but 10 to 14 inches of insulation is generally needed for satisfactory results. Your own home could require an even thicker layer of attic insulation.

It is also critical for the insulation to be evenly applied. There should be no low spots where the depth of the insulation varies from the rest of the attic floor. There should also be no gaps, such as around the walls or under the eaves.

Attic insulation is available in a variety of styles. The two most popular types are the blanket type insulation and loose-fill insulation. Blankets are sold in rolls or pre-cut batts. Loose-fill is a type of “blown-in” insulation requiring special equipment to install correctly. (Loose-fill should not be confused with foam, which is another type of blown-in insulation that is commonly used between interior and exterior walls although it is sometimes used in attics as well.) Loose-fill insulation can be added over blanket-type insulation, and the reverse is also true. This means that if you are considering adding more attic insulation, you are not restricted to using the same type that is already in place.

Due to the number of factors that must be evaluated when determining the appropriate amount of insulation for a specific home as well as the specialized skills required, consulting a professional roofing contractor can help achieve the desired results. Roofing contractors can evaluate your attic as a complete system, including its ventilation and roofing materials.
