The air seal and insulation are in place and passed county inspection.

Air sealing is the key to a tight house, high preformance house.
In this photo, caulk was placed in the gap between the studs thus stopping air flow.

This photo was taken in the basement. At the wall – floor joist connection caulk was used to close any gaps, the orange caulk is a fire-stop product. In this location there are two floor joist on exterior wall. In order to insulate the exterior band board, holes were drilled thru the inner band and the cavity was filled with foam.

The band board in this photo was foamed. Foam provides air seal and insulation. The home is insulated with cellulose. Cellulose is made of recycled paper and cardboard. Cellulose uses borates as a fire retardant.

There are two methods of installing cellulose: wet and dry. When applied wet, cellulose is mixed with water. The wet spray fills and seals extremely well. Applied dry, the cellulose is typically sprayed in the attic on the drywall or if the product is placed before drywall, netting is stapled to the walls or ceiling to keep the insulation in place until a drywall or equal is installed.

This photo shows both types of installation. The wall cavity was wet sprayed, the ceiling was netted and blow with a dry product.

Drywall was stocked today.
