As a homeowner in Toronto, you have many different home upgrades or renovations that you could get. However, if you are looking for the best value for your home upgrade budget, one of the best things that you could do is install energy efficient windows.

The reason that an upgrade to efficient windows is a good value is because it will reduce the cost of heating and cooling the home. In addition to that, energy efficient upgrades like windows add value to the home, and they can be a good selling point if you ever decide to move.

Your windows have a significant impact on your home’s energy efficiency. During the winter, it is heat loss, and during the summer, it is heat coming in from the outside. Energy efficient windows are designed to mitigate both of these effects.

With standard windows, you have a single pane of glass. With just the one pane, heat can easily transfer from one side to the other. As an additional point, standard windows may also be framed from materials that are more conductive, and this is an additional concern for heat loss.
When you go with energy efficient windows, you get a multi-pane design that helps to reduce the amount of heat flow. Not only do you have the two panes, but there is also a pocket of gas in between the panes. Heat does not transfer easily through still air, so this is an effective measure to improve the window’s ability to resist heat flow. Beyond that, the housing and framing of the window will be constructed of a material that is less conductive, and it may have several layers of material that act as insulation against heat loss.

To protect against heat absorption in the summer, the windows will also be treated with a low-emissivity coating. Usually, this is a coating of microscopic metallic oxide. This coating is clear, so you do not see it, but it reflects much of the sunlight back away from the windows.

Getting the Right Windows for Your Home

When you buy energy efficient windows, it should have information like the climate zone for which the windows are designed. If you want windows that are even better for insulating against the cold, you could consider buying windows that are designed for a colder climate.

While getting the right windows is an important step toward improving the energy efficiency of your home, installation is also a key concern. For the windows to perform as intended, they need to be properly installed and sealed. For this reason, it is a good idea to ensure that your energy efficient windows are installed by professionals.
