A homeowner in Brandy Station, VA had inefficient insulation in their attic and they wanted to make their main floor more comfortable. To fix this issue, we removed all of the old yucky insulation, air sealed the attic by closing all penetrations and top plates using polyurethane foam, and then we blew in TruSoft cellulose insulation to an R value of 49. This resulted in a much more comfortable main floor, as much less conditioned air could now escape from the attic.
