Power Smart home insulation tips

Almost 13 per cent of Manitoba’s annual energy use is for heating our homes. Here are some changes you can make around your home to save energy and achieve an even temperature throughout your home:

  • Caulk and seal gaps to keep the warm air in and the cold air out.
  • If your attic is much warmer than the outside air, your home may be leaking heat. Seal gaps and air leaks around light fixtures, pipes, ducts and exhaust fans in ceilings to save up to $20 a year.
  • Caulk and seal gaps to prevent air leakage:
    • 30 to 50 per cent of air leakage gets in underneath the baseboards and through the wall outlets.
    • 20 per cent of air leakage gets in through holes where plumbing pipes and telephone wires enter the house and other gaps.
  • If you are insulating a foundation with polyurethane foam, 4” of spray foam is needed to reach R-24.
  • If you are insulating a flat attic with loose fill insulation, look on the side of the bag of insulation for a chart that will help you figure out how many bags you need to reach the Power Smart level of R-50.

For example: to add R-20 to your attic calculate as follows: total square footage of attic / 35.6 = # of bags.
