Insulation and Weatherization
Insulation
Insulation is one of the most cost-effective energy efficiency upgrades you can do in your home. Insulation is inexpensive, increases year-round comfort, reduces noise and has a short payback period. Adding insulation is also a great DIY project which can often be completed in a weekend.
To be eligible for insulation rebates, the home must be electrically heated and the space being insulated must meet one of the existing conditions listed in the table below. An MEC representative must verify the existing condition before any isulation can be added. A post-install inspection is required to verify the new level of insulation.

Window Replacement
Window rebates are available for electrically heated homes with existing windows meeting the following criteria:
- Single pane with or without a storm window (any frame material)
- Double pane with an aluminum frame (vinyl or wood framed double pane windows do not qualify for rebates)
Before any windows are replaced, an MEC representative must conduct a site visit to measure the area of the existing windows. New windows cannot exceed the size of the windows they are replacing and must have a u-value of 0.30 or lower.
A rebate of $6-$8 per square foot are available for qualifying window and patio door replacements.
