Insulation effectiveness is measured in units of R-values, which are measurements of resistance to conductive heat flow or thermal resistance. The recommended minimum value for attic insulation for our area according to the Department of Energy is an R-30. The recommended minimum value for exterior wall insulation is an R-13.
Existing attic insulation must not be more than R-22, and must be raised to an R-30 or greater. Only areas that are adjacent to electric heat and air-conditioned areas will qualify (insulating garages, or other non-air-conditioned areas does not qualify). The SmartHOME program does not pay for the removal of existing insulation. An itemized invoice showing all charges and the square footage of the improved area is required.
Exterior walls must not have any existing insulation and must be raised to an R-13 or greater. Only areas that are adjacent to electric heat and air-conditioned areas will qualify (insulating garages, or other non-air-conditioned areas does not qualify).
