Ceiling Insulation

Insulate a minimum of 60 percent of the total ceiling area to qualify. When the roof has more than one type (i.e. attic, cathedral ceiling, flat roof), all grants are PRO-RATED based on the ceiling area that is insulated. The maximum grant for any combination of attic, cathedral ceiling and flat roof is $600. Grants listed reflect 100% of the ceiling area being of one roof type.  You must add additional insulation in the same location (i.e. attic floor vs attic ceiling) as the insulation present at the time of the pre-retrofit evaluation.

Increase the insulation value of

Your attic to achieve a total minimum insulation value of RSI 8.8 (R-50). 

Incentives for attic insulation will vary according to the existing level of insulation. For example, if you increase the insulation from a low RSI value, such as RSI 1.8 (R-10), to a new value of RSI 8.8 (R-50), you will receive a larger incentive than if you started from RSI 4.2 (R-24) and increased it to RSI 8.8 (R-50). Insulation value in RSI = R insulation value divided by 5.678.

Your flat roof and/or cathedral ceiling to achieve a total minimum insulation value of RSI 5 (R-28).

Add a minimum insulation value of RSI 1.8 (R-10) to your uninsulated flat roof and/or cathedral ceiling and qualify for a grant of $400.
