The main reason why we remove the old insulation is if it has been damaged by fire, water or infested with rodents. But more commonly, it is when no vapor barrier between the sheetrock and the insulation has been installed. In this case the old is removed, a 1.5”-2” layer of urethane is applied as your vapor barrier. Next baffles are installed along the edge of the attic. Baffles ensure that no insulation falls into the soffits and blocks the air flow of the attic space. Finally 12” (R40) of Igloo cellulose is blown in to achieve a final R50 factor.
In the rare instances where insulation removal is required, we hand-remove the fiberglass rolls and pack them in bags that are carefully removed from your attic. If the attic has blown material, we use a large vacuum to remove all the material. The vacuum is outside the house, this ensures a clean job where little or no debris enters the home.
