Blown-In Fiberglass and Cellulose Attic Insulation
According to the United States Department of Energy ENERGY STAR program, home heating and cooling costs can be slashed by up to 20% per year by properly sealing and insulating a home. Insulating the attic should be a top priority for preventing heat loss. As heat rises, a critical amount of heat is lost from the living areas of your home through an unfinished attic.
During the summer months, heat trapped in the attic can reduce a home’s ability to keep cool, forcing the home’s cooling system to work harder.
Ideally, the living space of the home should be insulated, and the roof should remain at the same temperature as the outside air. In the winter, this prevents cold outside air from traveling through the attic and into the living area of the home. In order to accomplish this, air must be allowed to enter soffit intake vents and to exit through ridge vents, gable vents or louver vents.
Preventing Ice Dams with Ventilation
Ice dams can be a sign of insufficient attic insulation or ventilation. Ice dams can be reduced through proper insulation and ventilation.
Adding Blown-In Insulation
Additional insulation may be blown-in over the existing to increase the R-value.
Notice the baffles at the edges of the roof. These extend above the insulation to ensure proper function of the soffit vents. Proper ventilation helps to keep attic temperatures closer to the outside temperature.
Proper insulation and ventilation results in:
- A reduction of energy bills.
- An extended lifespan of your roof.
- Inhibited mold and mildew growth in the attic.
- A quieter, more comfortable home.
