Insulation and Weatherization


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.
