Why is spray foam insulation the better alternative?

What-is-Spray-Foam-Insulation1In the average home, enough air to fill two Goodyear blimps escapes every day. This means that during cold winter months, the air inside your house that you are paying good money to heat, is being lost tothe cold outdoors each and every day!

For those of you who live in older homes, as much as 50% your heating and cooling bills could be attributed to air leakage. Even new homes with standard insulation could be losing hundreds of dollars-worth of heating and cooling costs through their walls every year!

All of this is due to conventional fibre insulation’s poor ability to restrict air leakage. As a result, this reduced R-value contributes to costly energy loss, moisture build-up, and even the transfer of airborne pollutants and pollens into your home.

Spray foam, on the other hand, does what conventional insulation cannot do by expanding to fill cracksor potential areas of air leakage, thus virtually eliminating infiltration. Additionally, because of its waterproof characteristics, spray foam is able to address moisture issues that conventional insulation cannot.

By maintaining comfortable humidity levels and guarding against air leakage in the cold and dry wintermonths, as well as keeping a cool and dry indoor climate during the peak of summertime heat and humidity, the benefits of spray foam remain substantial year round. All these factors combine to save you serious money in your home’s energy costs.

Spray Foam – Building Envelope

The building envelope is a system of construction materials and design components that work together in order to control the temperature, air movement, and moisture flows of a building. The “envelope” allows the flow in and out of a building to be pre-determined according to design, resulting in a morestable, comfortable, and healthy indoor environment for its dwellers.

Benefits of Spray Foam

By saving you on costly utility bills, strengthening the integrity of your home, and protecting the health of your family against dangerous molds, airborne pollutants and allergens, spray foam insulation stands head and shoulders above its counter-parts in the insulation industry.

Spray Foam:

Eliminates air and moisture infiltration
Maintains a comfortable climate in your home
Saves on energy costs
Strengthens the structure of a building
Is permanent; it does not “sag” over time
Acts as a barrier against dust and pollen
Reduces capacity requirements, maintenance and wear of HVAC equipment




Power Smart Home Insulation Program

Our Home Insulation Program offers rebates to homeowners who add insulation to their existing home. Eligible homeowners may receive a portion of the insulation cost. Follow these 3 steps to start saving:

  1. Qualify.
  2. Insulate.
  3. Get a rebate.

To qualify for the rebate:

To help you determine the most cost-effective insulation upgrade and other energy efficient improvements, assess your energy use with a Power Smart Home Energy Evaluation. You can complete the information online or order a mail-in assessmentSURVEY.

Find more information on insulation in our how-to videos and booklets.


Your home qualifies if:

  • you are the homeowner and the home has an active Manitoba Hydro account;
  • it is detached, semi-detached, or a mobile/modular home on a permanent foundation with a permanent water supply, and intended as a residence;

How to Take Part

Step 1: qualify

  1. Determine which area(s) of your home that you would like to insulate:
    • attic;
    • foundation;
    • exterior walls.
  2. Decide whether you will do-it-yourself or hire a contractor.

Discuss your insulation project with your retailer or contractor. Be prepared with these details:

  • the square foot measurement of your home;
  • the year your home was built;
  • your Manitoba Hydro account number;
  • what type of heating your home has;
  • the square foot measurement of the area to be insulated;
  • the existing R-value of the area to be insulated (read about R-value in our how-to booklets).

Your retailer/contractor will:

  • complete the required Home Insulation Program Rebate Application with you;
  • obtainPRE-APPROVAL for your project;
  • contact you when your insulation project has beenAPPROVED.

We may conduct a pre-installation verification beforeAPPROVAL is issued.

We offer detailed information about insulating measures and procedures for your home. For more information contact us at 1-888-MBHYDRO(1-888-624-9376) or contact your local district office.

Step 2: insulate

Once you have receivedPRE-APPROVAL, you can begin your project.

You will need to:

  • obtain all required building or electrical permits or ensure the primary contractor has done so (if you are unsure whether an electrical permit is required, contact your Manitoba Hydro district office);
  • ensure that the work meets the requirements of the Manitoba Building Code, all applicable bylaws, and is acceptable to inspection authorities;
  • select the materials to complete your project, or supervise the work of your contractor.

All installation and associated renovation work must be completed within 18 months ofAPPROVAL of your Home Insulation Program Rebate Application.

We will not act as mediator should you find your contractor's work unsatisfactory.

Step 3: get a rebate

Once you have completed your insulation project, you can submit your paperwork for a rebate.

You will need to submit:

  • the original, two-page, signed Home Insulation Program Rebate Application and Calculation Schedule;
  • all original receipts for insulation materials.

The form must include your contractor's or retailer's signature. The form must be sent to us within 30 days of finishing the installation.

We will process your rebate once you have submitted the appropriate paperwork. It may take up to 8 weeks.
