Adding insulation essentially keeps your residence cooler in the summer and warmer in the winter. For insulating an attic blown in insulation may be the ideal choice. This method allows the insulation to blown into place in the precise location and at precisely the right depth. This type of application is completed relatively quickly and can be a cost-effective solution. It is best to air seal the attic in combination with insulation to provide the highest level of energy efficiency and energy savings.
Air sealing and a continuous air barrier between the attic and the home’s conditioned (living) space are important not only to save energy and reduce fuel costs but also to prevent moisture from becoming a problem in the attic. Sealing holes in the attic improve chimney and flue performance by reducing competition for air in the attic. Air sealing a leaky attic also reduces the house’s “suction” (or stack effect) so fewer contaminants are drawn up into the house from the ground. Areas in attics that are often the sources of air leaks are soffits (dropped-ceiling areas, duct chases, plumbing chase), around recessed can lights, around flue pipes, around ducts, and at attic hatches.
