Window treatment

Inefficient windows can increase your energy bills and make your dwelling uncomfortable. These tips can help make your windows more efficient year-long:

  • Hang curtains with white, plastic backings to act as insulation and to retain cold air in the summer and warm air in the winter.
  • Seal windows with caulk to close any air leaks and cut energy costs by 5 to 10 per cent.
  • Create exterior shade by installing things like awnings to help keep your home cool in the summer. These items can block sunlight and reduce heat gain by 65 to 77 per cent.
  • Install storm windows during autumn. If you don’t own any, consider purchasing low-emissivity storm windows, which can lower heating costs by 12 to 33 per cent and cost only a quarter of the price of a total window replacement.
  • Watch for excessive condensation—a sign that a window needs to be repaired or replaced.
  • Consider weather stripping to prevent air leakage at moving window parts. Foam or gasket weather stripping can be applied to the sides and the sashes of windows.
