| Attic air sealing and insulation: Sealing the air leakage into the attic with Zero Draft Polyurethane foam keeps the warm conditioned air inside where it belongs.
Adding Weather Shield cellulose attic insulation made this home much more comfortable in summer and winter and brought it up to today's building code standards. During re-roofing is the best time to repair attic issues such as air leakage and inadequate insulation.
Inadequate insulation in walls makes for a cold and drafty home. This 1912 home was very cold and drafty prior to Zerodraft's craftsmen installing Wall Bar cellulose insulation.
