BE7: Grade 2 insulation or better installation quality (floors, walls, ceilings)

Purpose

The efficacy of a building's thermal envelope is highly dependent on the quality of the installation of the insulation. A low-quality insulation installation can lead to a degradation of the assembly R-value, leading to hidden costs for homeowners through excessive heat gains and losses.

Criteria

Install all insulation per manufacturer’s recommendations to achieve a minimum quality Grade II as specified by criteria set forth by RESNET. Ensure that all insulation is in substantial contact with the building's air barrier and that batts are cut to fit around electrical wiring/receptacles and plumbing.

Confirmation

The EarthCraft Technical Advisor will visually confirm compliance of criteria at mid-construction and final inspections.
