This attic was used for storage and had limited insulation. After we air sealed, we installed a 2 inch platform of SilverGlo board insulation where the storage deck was going to be. We then built the storage platform and the walls out of plywood. Underneath the plywood and foam board insulation, we dense packed cellulose insulation to increase the R-value. The remaining portions of the attic are insulated with a loose filled cellulose insulation.
