Attic Insulation Case Studies: Cold Rooms over Garage in Ashburn, VA

Wednesday, March 13th, 2019 by Crystal Bonner


Homeowners living in Ashburn, VA had an uncomfortable top floor. It was always too hot in the summer and too cold in the winter. The rooms above the garage were especially cold in the winter.  


To make the home more comfortable upstairs year round we air sealed and insulated the garage ceiling, air sealed and insulated the attic, sealed the chimney chase, installed can light covers, and encapsulated the duct system. This created a building envelope that was better sealed and more secure, allowing less air flow into the house, and keeping the conditioned air inside the house for much longer. Now that the garage ceiling was insulated, the rooms above it stayed much more comfortable.
