In Homes, 1/2 point is earned if the insulation used in 90% of the total insulated surface area of walls plus roof plus floor combined complies with California “Practice for Testing of VOCs from Building Materials Using Small Chambers.” Spray Polyurethane Foam complies with this standard in its finished state. If Spray Polyurethane Foam is used for 90% or more of a home’s insulated wall + roof + floor area, the project would earn 1/2 point.
