Financial Assistance for Improving Insulation - Rénoclimat Program

Improving insulation

When the roof, foundation and exterior walls of your home are well insulated, they help your home resist better to cold in the winter and excessive heat in the summer. They also make it easier to maintain a more comfortable indoor temperature and control heating costs. This explains why various renovations targeting the improvement of the home’s insulation are eligible under the Rénoclimat program.

The energy evaluation report that you will receive will indicate the most pertinent type of insulation work to carry out on your home.

Improving the insulating value of a roof

  • Insulation work must target at least 20% of the total surface area of the roof to be entitled to financial assistance.
  • If the roof is composed of more than one type of roof (for example, attic, cathedral ceiling, flat roof), the amount will be calculated on a pro rata basis, i.e. on the basis of each roof type and its respective surface area.
Type of roofFinancial assistanceFactors considered in the calculation

Attic

Cathedral roof

Flat roof

From $35 to $975
  • Percentage of insulated surface
  • Pre-work insulating value
  • Post-work insulating value
It is important to check all the required conditions by consulting the Rénoclimat normative framework (PDF, in French only).

Before undertaking your renovations, you can consult the section on Practical advice to learn more about roof insulation.

Improving the insulating value of a foundation

  • Insulation work must target at least 20% of the total surface area of the foundation walls (common walls not included) to be entitled to financial assistance.
  • When there is a basement and a crawl space, financial assistance is calculated on a pro rata basis, i.e. on the basis of their respective surface area.

Foundation with a basement

Type of workFinancial assistanceFactors considered in the calculation
Insulating foundation walls of basementFrom $165 to $1,625
  • Percentage of insulated surface
  • Scale of the increased insulating value
Insulating and sealing the end joist of the basement $165
  • Scale of the increased insulating value

Foundation with a crawl space

Type of workFinancial assistanceFactors considered in the calculation
Insulating exterior walls and end joists of crawl spaceFrom $650 to $1,300
  • Scale of the increased insulating value
Insulating 100% of the floor above the crawl space $325
  • Scale of the increased insulating value
It is important to check all the required conditions by consulting the Rénoclimat normative framework (PDF, in French only). Some conditions apply to semi-detached and row houses.

Before undertaking your renovations, you can consult the section on Practical advice to learn more about how to insulate foundations. You can improve the insulation of your home’s foundation by insulating from the interior or the exterior based on the condition of the walls, space limitations and regulations.

Improving the insulating value of exterior walls

  • If you are planning to change the exterior siding of your walls, it would be a good idea to improve their insulation as well.
  • At least 20% of the total surface area of the exterior walls (common walls not included) must be insulated to be entitled to financial assistance.
