Insulation Considerations & Solutions

Adding insulation beneath your roof can help control the temperature inside your home and thereby reduce the energy costs associated with your heating and cooling needs. Different roofing materials and building structures will require different types of insulation.

Insulation is rated for its resistance to heat flow with an “R-Value”. The higher the R-Value, the greater the insulating power. To get the marked R-Value of any insulation, the insulation will need to be installed properly.

Ultimately, your energy savings from adding insulation to your home will depend upon how much insulation you currently have; as well as the climate, the type and size of your house, your energy usage patterns and family size.

Depending on the level of insulation you choose, you could be eligible for a federal energy efficiency tax credit for insulating your home. The most common insulation materials are described below.

Radiant Barrier

Aluminum sheathing beneath the roof that minimizes radiant heat gain during summer months and minimizes heat loss in colder seasons.

Rolled Insulation

Typically made of fiberglass and available in different thicknesses, this insulation is unrolled and cut to fit the spaces between the attic ceiling joists beneath the roof.

Blown Insulation

Typically comprised of cellulose or fiberglass, this insulation is blown into the spaces between the attic ceiling joists.
