Larry Janesky from Dr. Energy Saver walks us through energy upgrades in the attic and basement of a condominium unit, improving its efficiency and comfort levels. They start by bringing the R-Value of the attic insulation to the U.S. Dept. of Energy's recommended value for the region, by blowing additional layers of loose fill fiberglass insulation into the attic. Next, to make the basement more comfortable and energy efficient, injection foam insulation is applied to existing wall cavities. Injection foam insulation doesn't expand or stick like spray foam insulation, and can be used in wall cavities to add R-Value to walls previously insulated with fiberglass. Injection foam also seals gaps, thus preventing air leakage. Injection foam is water-based, so there are no toxic fumes or harsh smells.For more information about Energy Upgrades or to schedule a Free Estimate, contact Dr. Energy Saver.
