Insulating with the Super Attic System | 1-888-225-6260 In this job, Dr. Energy Saver opted for installing the SuperAttic™ System, because it will prevent enormous energy losses from the ducts and HVAC unit housed in the attic. As a result, this home is now healthier, quieter and more energy efficient. A properly insulated and air sealed attic is one of the main components of a green, energy efficient home. Because the heated air in a house tends to rise and escape through openings in the upper levels of the building, attics need to be sealed to prevent air leakage. Air leaks in attics are the source of many problems, including ice damming on the roof, and mold. In addition, inadequate insulation causes drastic variations in attic temperatures throughout the year. Scorching attic temperatures during the summer or freezing temperatures during winter make your heating and cooling system work harder to keep your home comfortable. If you have HVAC and ducts running through the attic, the energy loss is even more significant. There are two options to create an energy efficient attic. You can seal the living space from the attic and blow a thick layer of insulation on the attic floor, excluding the vented, unconditioned attic from the internal building envelope. Or you can use the SuperAttic™ System, to seal, insulate and condition the attic, including it in the building envelope, while keeping the roof effectively vented. Is your improperly insulated attic costing you money? Would you like to enjoy a more comfortable home and lower your heating and cooling bills? Dr. Energy Saver can help!

In this episode of the On the Job series, Larry Janesky, owner and founder of Dr. Energy Saver, walks us through the many ways they made a typical cape house more energy efficient.

This cape had poor attic insulation and serious air leakage, which increased the homeowner's energy bills and caused serious ice damming problems during the winter. As the snow melted on the roof, a ridge of ice forced trapped water to leak into the house. The water damage to the attic and living area raised health and mold concerns. The problem was so significant that during an especially heavy winter storm in the previous year, the homeowner had to climb on the roof and manually break the large ice ridges to keep water from pouring down his kitchen cabinets.

To fix this problem, Dr. Energy Saver completely air sealed the attic to keep heated air in the living space from leaking into the attic. The bathroom fans that were venting into the attic were fitted with ducts to vent to the outside, thus preventing all the air and moisture from leaking into the attic space.

Cape style homes like this one usually have a knee wall space. It is a small space created at the angle between the roof and the floor. A knee wall is usually a big source of energy waste. So the next step was to insulate and air seal the knee wall using a special type of rigid foam board insulation called SilverGlo™, which is lined with a radiant barrier to help conserve heat.

The last step was to insulate the attic, which was originally insulated with a thin layer of fiberglass batt insulation, which measures way below the R-60 value recommended by the U.S. Department of Energy for attics in that region. Besides having insufficient R-Value, fiberglass insulation does not stop air flow.

To insulate this attic, Dr. Energy Saver chose TruSoft™ cellulose insulation. Cellulose insulation is basically recycled newspaper that's treated with borax to prevent pest infestation and mold growth, and fire retardants which give the material an excellent fire safety rating. Cellulose insulation is denser than blown fiberglass and has a higher R-Value of 3.7 per inch. A layer of 17 inches was blown into the attic, with special attention to rafter bays and small cavities created by typical cape style architectural features.

This cape is now ready for winter. The homeowner has a more comfortable house, and his energy bills are much lower.
