Removing Attc Insulation

February 4th, 2013

An alarming number of homeowners believe their homes to be energy efficient simply because their attics have insulation. This just is not the case. There are many variables that must be taken into account when determining a homes energy efficiency based on insulation; the age, type, and condition of the attic insulation will all have an effect on how efficient a home is. In fact, many people are surprised to learn that removing attic insulation and hiring a professional, such as those at Attic Plus, is necessary to improve their home energy rating. Onward and Upward: There Goes Your Heat and Your Pocket Book During the winter months, warm air vented through a home HVAC system will circulate around the main rooms of a home. This warm air will eventually rise upward and make it’s way to the attic. This is where the majority of home energy loss occurs. Depending on what type of attic insulation is used, the warm air will continue to rise upwards and eventually push through the roof and out of the home. Effectively installed insulation will prevent warm air from filtering through the attic rapidly enough to cause any sort of drastic temperature changes. Type of Insulation: For all intents and purposes, there are two primary types of attic insulation: blown in and batting. Batting is less effective than blow in insulation since, if installed incorrectly, warm air can escape through gaps in between the batts. Ventilation: Adequate ventilation is paramount when it comes to attics. Proper ventilation ensures that moisture and gasses do not build up and cause mold or mildew to form. Since proper ventilation has a direct effect on a home’s air quality, it is essential to enlist the services of a professional to install attic insulation. Amount: The federal government places stipulations on what type and amount of attic insulation is needed to facilitate adequate protection and heat exchange. Professional insulation installers have the knowledge needed to provide recommendations. Adding To or Removing Attic Insulation: Overtime insulation will begin to settle and compact. This means that it can no longer be considered effective when preventing air transfer. This will often require the insulation to be replaced or to have more added on top. Depending on the type of insulation, most homeowners elect to add an extra layer since doing so is more cost effective than a rip and replace solution.
