Shall be used to describe an installation with substantial gaps and voids, with missing insulation amounting to greater than 2% of the area, but less than 5% of the surface area it is intended to occupy.

*This includes insulation that is not in substantial contact with sheathing on at least one side of the cavity or insulation in a wall that is open (unsheathed) on one side, and exposed to the exterior.

Shall be used to describe an installation with moderate to frequent installation defects: gaps around wiring, electrical outlets, plumbing and other intrusions; rounded edges or “shoulders”; or incomplete fill amounting to 10% or more of the area, with less than

70% of the intended thickness. *Wall insulation must be enclosed on all six sides, and must be in substantial contact with the sheathing material on at least one side (interior or exterior) of the cavity.

*Wall insulation must be enclosed on all six sides, and must be in substantial contact with the sheathing material on at least one side (interior or exterior) of the cavity.

TECH: 2004-01

Shall be used to describe an installation that is generally installed according to manufacturer’s instructions and/or industry standards. A Grade I installation requires that the insulation material uniformly fills each cavity side-to-side and top-to-bottom, without substantial gaps or voids.

Proposal1. Survey homes in Northwest (Numbers from Brady’s memory)

1. Oregon: 30 homes

2. Washington: 30 homes

3. Idaho: 15 homes

4. Montana: 10 homes

In all cases, no more than three homes to come from a single subdivision.

All non-Energy Star homes to avoid homes influenced by program efforts.

2. Ecotope to take survey data and ascertain baseline thermal performance for building assemblies, esp. walls.

3. Determine thermal performance improvement expected from additional training/inspection or alternate insulation systems.
