With the weather turning colder, you’re doubtlessly looking for a way to keep heating costs down this winter, while keeping your family warm.

We at Thermo-Bilt Windows, the Greater Toronto Area’s leading window and replacement window service, recommend having windows that prevent heat transfer (i.e., heat escaping your home during the winter) installed, as many homes often lose heat through the windows. This will cut down on your heating bill and help you to save money during the winter.

But you may be wondering what the best type of window to prevent heat transfer is. We at Thermo-Bilt tell our clients that there are several they can choose from, which our experts will install quickly, keeping customers warm and cozy while lowering their heating costs. Here are your options:

  • Extremely Low-E Rating: This type of window is made with LoE2-rated glass to keep your home warm and comfortable during the winter.
  • Vinyl Windows: Vinyl windows are widely recognized as being one of the most energy-efficient window designs on the market. As an added bonus, vinyl windows will keep your home cool during the summer as well.
  • Double-Paned Windows: Another excellent way to keep warm air in during the winter is to have double-paned windows installed. When used with a vinyl window frame, this can lower heating costs by up to 25%.

If you’re looking to hold off until the spring to have new or replacement windows installed, there are some ways you can keep heat in during the winter:

Tip#1: Find any areas where heat is escaping—e.g., around windows, doors—and apply a sealant to them.

Tip#2: Attaching weather stripping on spots where heat might be escaping before it gets too cold and your furnace kicks in is another method of preventing heat transfer.

Tip#3: Condensation is another cause of homes losing heat during the winter. Make sure that any areas that have high levels of condensation, such as the kitchen or bathroom(s), have proper ventilation, and that you take the time to let any moisture that may form dry.

Tip#4: Installing thermal-backed drapes creates a barrier between the window and the room it’s located in. For an added layer of protection, attach the drapes using Velcro.

Tip#5: To ensure that your home stays warm during the winter and your heating bill doesn’t go up, have shutters installed on the outside of your windows for an additional layer of protection against the elements.

Even if you follow all of these tips, Thermo-Bilt advises its customers to get energy-efficient windows installed before the cold weather hits. If you combine this with some of the tips given above, you’ll stay warm and keep your heating costs down during the winter.
