Rénoclimat financial assistance for improving home insulation

Insulation improvements are eligible for Rénoclimat financial assistance. If your energy evaluation report recommends increasing your home’s insulation, do not hesitate to proceed with the work.

Proper insulation of the roof assemblies, foundation, and exterior walls of a home helps maintain a comfortable indoor temperature year-round, in both winter and summer. It also optimizes energy consumption for heating and cooling.

Rénoclimat financial assistance is calculated for each section of the home based on the improvement in insulation level compared to the insulating value measured at the time of the pre-retrofit evaluation.

• The post-retrofit insulating value must reach the targets recommended by the program.
• The targets are indicated in your energy evaluation report.
• The pre-retrofit values are listed in the homeowner information sheet and in the energy evaluation report.

To be eligible for a grant, insulation work must cover a sufficient area of the targeted section (roof, exterior walls, foundations, or exposed floor). The required percentage is specified in the conditions to be met.

Participant's guide

For insulation improvement, Section 4.1 of the Rénoclimat Participant’s Guide (PDF 1.76 Mb) provides additional details on:

• Insulating values;
• Targets to be met or exceeded to maximize the grant amount;
• Conditions to be met to ensure the retrofit is eligible.

Do not hesitate to discuss with your Rénoclimat energy advisor or your contractor to ensure you meet the targets.

To qualify for financial assistance, you must add insulation to at least 20% of the total area of your roof assembly.

If the home has more than one type of roof assembly (e.g., attic, cathedral ceiling, flat roof), the grant amount will be calculated proportionally based on the type of roof assembly and its respective surface area.

Factors considered in the calculation of the grant amount:

• Percentage of the surface insulated
• Pre-retrofit insulating value
• Post-retrofit insulating value

Refer to Section 4.1 of the Rénoclimat participant’s guide (PDF 1.76 Mb) for additional details.

If you plan to replace the exterior wall cladding of your home, take the opportunity to improve its insulation.

To qualify for financial assistance, you must add  insulation to at least 20% of the total exterior wall area (excluding shared walls).

Factors considered in the calculation of the grant amount:

• Percentage of surface insulated
• Extent of improvement in insulating value
• A different calculation method applies to semi-detached and row houses.

Refer to Section 4.1 of the Rénoclimat Participant’s Guide (PDF 1.76 Mb) for additional details.

To qualify for financial assistance, you must add insulation to at least 20% of the total foundation wall area (excluding shared walls).

For basement rim joists, you must add insulation to at least 80% of the total surface area to qualify for financial assistance (excluding rim joists on shared walls).

If the home has both a basement and a crawl space, the grant amount will be calculated proportionally based on their respective surface areas.

Factors considered in the calculation of the grant amount:

• Percentage of surface insulated
• Extent of improvement in insulating value
• A different calculation method applies to semi-detached and row houses.

Refer to Section 4.1 of the Rénoclimat Participant’s Guide (PDF 1.76 Mb) for additional details.

You can improve the insulation of your home's foundation by insulating from the exterior or interior, depending on the condition of the walls, space constraints, or regulations.

Refer to the Helpful advice/Insulation section to learn more about foundation insulation.

Exposed floors are floors located above an unheated space (e.g., a floor above an unheated garage).

To qualify for financial assistance, 100% of the exposed floor surface must be insulated. A minimum of 14 m² must be insulated.

Factor considered in the calculation of the grant amount:

• Extent of improvement in insulating value

Refer to Section 4.1 of the Rénoclimat Participant’s Guide (PDF 1.76 Mb) for additional details.

For duplexes, triplexes, and multi-unit residential buildings, the financial assistance calculation method differs.

The grant amount for insulation retrofits is increased by applying a multiplier corresponding to the number of units in the residential building.

Refer to the Amounts for multi-unit residential buildings page for additional details.
