Attic Insulation Photo Album: Remediation & Insulation in Gregory, MI
The symptoms of the problem were black colored mold growth on the gable walls, the gable wall OSB was wet from the bottom plate to the top of the blown insulation. The problem was caused by the bath fan ducts leaking below the insulation where they were disconnected from the couplers at the gable wall vent. The warm humid air coming from the bath fan exhausts was traveling through the insulation and getting trapped between the OSB on the gable wall and the insulation causing the OSB to become saturated. Our solution was to remove all of the blown fiberglass and fiberglass batt from the attic floor, remediating the mold that was present on the gable walls and on some of the roof sheathing and rafters. We used Mold X2, DuroVent Venting Baffles, 4" SilverGlo (Hatch Insulation), Weather-stripping, Adhesive, ZypFoam, 1/2" Foamboard (Insulation Collar), TruSoft Cellulose. The homeowner now has a healthy, clean attic that is going to supply comfort and savings for many years.
