The Canadian Greener Homes Grant allows homeowners to increase their home insulation. This slows the rate of heat loss, resulting in improved energy use and can help save money. The insulation’s resistance to heat flow is measured using both an RSI value and an R-value. R-value is the imperial measurement and the Résistance Système International (RSI) value is the metric measurement. The higher the resistance value, the slower the rate of heat transfer through the insulating material. Recommendations on insulation improvements and the calculation of your incentive will use these values. Read more about insulation materials.

Attics

Relatively easy access makes the attic a favourite starting point to insulate for many homeowners. Even if an attic is already insulated, you may be able to improve comfort and increase the energy efficiency. Learn more about insulation

Eligibility criteria for reimbursement:

  • Insulate a minimum of 20% of the total area of your attic or ceiling.
  • You must increase the insulation value (R-value or RSI).
  • Add insulation in the same location (e.g., attic floor vs. attic ceiling) as the insulation present at the time of the pre-retrofit evaluation.

Important:

  • The grant amounts reflect a situation where 100% of the ceiling area is one roof type. Your home may have a combination of ceiling types.
  • The total grant for any combination of attic, cathedral ceiling and flat roof insulation cannot exceed $1,800.
  • The total amount of your reimbursement will be calculated based on the total percentage of your attic that you choose to insulate. For example, if you insulate 80% of your attic you would qualify for 80% of the amount listed below.

GRANT AMOUNTS (BY LEVEL OF ADDITIONAL INSULATION ADDED YOUR HOME)

From current level of insulation in your home at the time of the pre-retrofit evaluation :If you achieve a total minimum insulation value of RSI 8.81 (R-SO) for your atticIf you achieve a total minimum insulation value of RSI 4.93 (R-28) for your flat roof and/or cathedral ceilingIf you insulate your non-insulated flat roof or cathedral ceiling to increase its insulation value by a minimum RSI 3.52 (R-20)
No insulation and up to RSI 2.11 (R-12) $1,800$600$600
Greater than RSI 2.11 (R-12) and up to RSI 4.40 (R-25)$600$250N/A

Exterior Wall Insulation

The walls of your home can account for about 20% of heat loss. In addition to heat loss through the walls, there are many cracks and other access points that allow uncontrolled air and water leakage into and out of your home. To help choose the right product for your job, review the characteristics of blown-in and foamed-in insulations.

Eligibility criteria for reimbursement:

Important:

  • The total amount of your reimbursement will be calculated based on the total percentage of your wall that you choose to insulate. This means if you insulate 80% of your wall area, you would qualify for 80% of the amount listed below.
  • For a semi- detached or end unit row house, you will not qualify for the full amount of the grant. The maximum you would be eligible for is 75% of the listed amounts. For a middle unit row house, the maximum grant you would qualify for is 50% of the listed amounts.
  • There are no incentives available for insulation of walls between individual units.

Exposed Floor

Some homes have open foundations and exposed floors. Insulating the floor of those areas, such as the floor of a room above an attached garage or the floor of an addition where the floor is exposed to the outdoors can improve comfort and save energy. The intent of this measure is to provide insulation to the floors exposed to the outdoors. Learn more about insulating exposed floors.

Eligibility criteria for reimbursement:

  • Insulate the entire exposed floor area (minimum area of 11 square metres or 120 square feet).
  • This can include overhangs and floors above unheated spaces such as an unheated garage.
  • Crawl spaces are excluded. See grants for crawl spaces.

Basement/Foundation Insulation

Did you know that basements can account for about 20% of a home’s total heat loss? Air leakage can also occur through basement windows and at the top of the foundation wall. Learn more about insulation a basement and foundation.

Eligibility criteria for reimbursement:

  • Insulate a minimum of 20% of the wall area of the foundation, including basement and crawl space walls.

Important:

  • You can combine the grants shown below: i.e. adding insulation to the basement header and wall insulation.
  • For a semi- detached or end unit row house, you will not qualify for the full amount of the grant: the maximum you would be eligible for is 75% of the listed amounts.
  • For a middle unit row house, the maximum grant you would qualify for is 50% of the listed amounts.
  • There are no grants available for insulation of walls between individual units.
  • When both a basement and crawl space are present, all applicable grants are pro-rated to a maximum of $1,500 based on the total wall area and the additional insulation.

Crawl Space

Did you know that a crawl space can be insulated in two ways? The walls of the crawl space can be insulated on the inside or the outside. The house floor above it can also be insulated.

Eligibility criteria for reimbursement:

  • Add insulation in the crawl space wall and header, or ceiling.
  • Insulate the entire area noted in the Recommended Upgrade Report.
  • If you are also insulating your basement, the maximum you can receive for insulating both areas is $1500.

Important:

  • If you live in a semi- detached or end unit row house, you will not qualify for the full amount of the grant – the maximum you would be eligible for is 75% of the listed amounts.
  • If you live in a middle unit row house, the maximum grant you would qualify for is 50% of the listed amounts.
