You’d be surprised at how much influence the attic has on the home’s energy efficiency and heating and cooling performance. A well-designed and maintained attic can help keep your Chicago area home cool in the summer and warm in the winter, plus ease the strain on your checkbook. However, a poorly insulated and leaky attic, without proper ventilation, will force the furnace and A/C to work harder to keep you comfortable year round. Learn how you can improve attic and energy efficiency.
- Insulation – Without effective insulation in the attic, heat from the living spaces will transfer upward in the winter, forcing the furnace to work harder to provide comfort below. A warm wintertime attic will also keep the roof warm, increasing the likelihood of damaging ice dams. (These occur when snow melts on the higher parts of the roof and then refreezes at the edge of the roof, where it’s colder).In the summer, heat energy in a superheated attic will transfer downward into the living spaces, resulting in higher A/C bills and reduced comfort. An HVAC technician can advise you on the type, amount and location of insulation to place in the attic, as well as install it for you.
- Air sealing – A leaky attic can have the same negative effects as one with poor insulation. Warm air from living spaces will rise into the attic, forcing the furnace to work overtime to compensate. To avoid this, make sure the attic floor and walls are properly sealed and insulated, as well as the attic hatch or door.
- Ventilation – A healthy attic needs an effective exchange of stale inside air with fresh outside air, both through passive ventilation fixtures and active ventilation by way of an attic fan. In the summer, without proper ventilation, attic temperatures can rise to 150 degrees during especially hot days. Some of that heat eventually will work its way into your home. In the winter, ventilation will help prevent ice dams, as described previously.
