Window have an amazing effect on the cooling and heating needs and costs of a Canadian home, as well as the comfort level experienced by its occupants. Windows are easily the weakest link in a home for heat gain in the summer and heat loss in the winter.

An energy efficient window is one that helps to keep a constant temperature in a room, thus conserving on the energy wanted to heat or chill the room. For a start, the energy efficiency of any window can be improved by insuring that it is well looked after and has not got openings in the frame that will cause drafts.

Vinyl windows are generally multi-glazed, and while double glazed windows are good insulators, the triple-glazed windows that are becoming increasingly more popular offer unbelievable savings in energy costs, keeping the heat in during cold winter months, and increasing the effectiveness of your air conditioner cooling during hot summers. While double glazing offers a layer of air between the two panes, triple glazing provides two layers that offer an exceptionally high degree of insulation.
