Upgrading your insulation

Your home has a building envelope that includes the exterior walls, foundation, roof, windows and doors. The envelope should keep out extreme temperatures, moisture, dust, and wind.

By properly insulating your building envelope, you will reduce heat loss, create a more comfortable living space, and reduce your energy bills. Some of the signs that might indicate insulation problems are high heating costs, cold walls and floors, uneven heating levels within your home, or mold growth on your walls.

The initial amount of insulation added to an un-insulated area makes a big difference, and adding insulation to top up an area that isn’t sufficient also contributes to reducing heat loss. The measure of how well insulation material resists heat transfer is called its R-value, while the metric equivalent is RSI. The higher the R or RSI-value of a product, the better it resists heat transfer.

To increase the insulation levels in your home:

  1. Determine which areas of your home’s envelope require additional insulation, or may have moisture problems or drafts.
  2. Take note of areas in the attic, walls, or foundation that do not have any insulation, as these areas are likely to have the greatest impact on lowering your energy bills.
  3. Consider if you will do-it-yourself or hire a contractor.

Regardless of which option you choose, do your research. You are more likely to get the results you want if you are knowledgeable about the work. 

Most importantly, before the work begins, make sure to apply for pre-approval to Manitoba Hydro’s Home Insulation Program. You can do this by filling out an application with your insulation retailer or chosen contractor. If your project and home qualify you will receive a rebate for up to 100 per cent of your insulation material costs. If your home is poorly insulated, the rebate along with the energy savings you will realize will make your insulation project very worthwhile.
