Before and After Re Insulated Attic in Potomac, MD: The attic had blown fiberglass which resulted in not having the insulation it needs to keep the home comfortable and energy efficient. We replaced the blown fiberglass with blown cellulose insulation. This home resulted with a blanket of insulation over the top of their house that is far less penetrable by cold or hot air, more comfortable house, and lower electric bills.
