Attic Insulation

For attic insulation, the final level of insulation (preexisting and new) must have a minimum R-Value of R49. A final depth of at least 15” is generally sufficient to reach the required R49 value.

Here are some tips for applying for the rebate.

Window Replacement

Windows must have a U-factor of 0.30 or lower.

• The grant amount is $300 per window, with a $3,000 maximum award.
• The window must separate a heated space from an unheated space and must replace a single-pane window with a double- or triple-pane window.

According to the Department of Energy, heat gain and heat loss through windows are responsible for 25% to 30% of residential heating and cooling energy use. For windows, the rate of heat loss is indicated in terms of the U-factor. The lower the U-factor, the greater a window’s resistance to heat flow and the better its insulating value.

Here are some tips for applying for the window replacement rebate.
