Air Sealing
We sealed all accessible penetrations and top plates with expanding polyurethane foam.
Extending Bath Fan Duct
We extended the bath fan duct through the roof. This included a butterfly air control baffle and exterior Kozy Vent Roof Vent Hardware.
TruSoft Cellulose Insulation
The last step was to blow in TruSoft cellulose insulation. The benefits of TruSoft compared to fiberglass insulation is that the TruSoft cellulose will not burn, get moldy, or attract pests.
Old Insulation

Air Sealing
Many times, air sealing your attic, basement, and air ducts is the most effective because of the air leakage that occurs in these areas.
ZYP Foam
We use Dr. Energy Saver's exclusive ZYP Foam, which is a low-pressure one-component polyurethane foam sealant designed to seal, fill, bond, and stop air infiltration in areas where a fire block product is required.
