Photo Album: Inadequate Insulation in Attic in Ann Arbor, MI
The homeowner had Balsam Wool Batt insulation on the roof deck from the '60s in their attic space that was either deteriorating and falling and/or missing between rafters. Our solution was to remove all of the Balsam Wool insulation from the roof deck and vacuum the insulation that had fallen down on the attic floor to give them a clean attic space for storage. We used a combination of R-19 Batt fiberglass insulation and baffles to insure the attic was breathing properly between the insulation and the roof deck.
