An attic ladder for access is justified for the many trips, careful preparation, and heavy hauling to bring up insulation bags. This job includes my first employment of plywood soffit-vent baffles. Two layers of found insulation have been stripped of kraft facing, and are layered to fill and cover 2x4 truss bottom chords. A top layer of R19 parallel to trusses brings total insulation to about R40. The R19 top batts are Johns Manville AU333 in high-quality consistent shapes 24" x 48".
