This homeowner in Bristol, CT called us looking for attic insulation. He also was looking for a radiant barrier. When our Home Comfort Specialist came out to the home, he spoke to the homeowner about what he wanted for the home. This attic was being used as storage, and he was looking to improve his energy efficiency. Vented attics are hostile places - 30˚F in winter and 125˚F in the summer. They are very bad places to store things, and the worst place to locate ducts because they are the extreme opposite temperature as the air in the ducts that the homeowner paid to heat or cool. The attic floor allows air from inside the house to leak into the attic where it is lost. For each cubic foot of air that leaks out, a cubic foot of air from the outside enters the bottom of the house, making the lower levels cold and drafty. Heat from the house in the attic melts snow on the roof where it refreezes at the eaves causing destructive ice damming. In the summer, the sun heats the roof to 160˚F, which radiates to the attic and then to the ceilings and rooms. Results - Major heat loss to the attic from house and ducts in winter, and heat gain in summer, uncomfortable rooms, more drafts upstairs and downstairs, higher fuel/electric bills.
We had the perfect solution for this customer. In this solution, we install our SuperAttic™ system in the attic. SilverGlo™ EPS foam insulation board with graphite is installed on the underside of the roof deck. The graphite gives it superior R-value and a foil face on both sides reflects heat out in summer and back in during winter. The roof is still vented, kept cold in winter to prevent ice damming. In summer, excess heat is vented out. The attic is now part of the conditioned space in the home, and ducts in the attic are no longer in a hostile environment. The attic is clean, less dusty and suitable for storage. Results - The home is less drafty, warmer in winter and cooler in summer, lower fuel and electric bills, less dust.
