In the winter, the attic is cold and the warm conditioned air in our home rises. As the warm air touches the cold ceiling that air then cools, and sinks this cycle continues in a process called the "Convective Loop" the reverse is true in the summer. A hot attic warms up your ceiling and radiates heat down into the rooms below and heats the room. This results in your home feeling drafty, being hard to heat and cool and high energy bills.
