As we slowly make the transition into fall, you might want to start preparing for the colder weather that’s heading our way.

This is an incredibly inexpensive way to seal any drafty doors or windows that may be causing you issues. Weatherstripping seals any gaps that may be between the sashes and the frame of your windows. There are a variety of types of weatherstripping that you can use to do so, including nail-on tubular gaskets, spring bronze, v-strips, and more. Each kind is suited to a different type of window frame and severity of the gap.

Window Film

Window film adds another layer of insulation to any glass window or door in your home. There are a few straightforward steps that you can follow. The first step is to cut the window film to the size of your window. Then, you will want to mix together soap and water into a spray bottle, spraying the glass surface with the solution. Next, apply the cut film to the glass and use a hard, flat edge—like a credit card—to smooth out any ripples or bubbles.

Insulated Curtains

Hanging some insulated thermal curtains can also be a great way to keep out the cold during winter. These curtains are lined in order to prevent air from exiting your home through your windows, which we all know if a massive source for the heat exchange you may be experiencing. This way, you will be able to regulate the temperature in your home without having to overwork your heating unit. This will definitely reflect nicely on your energy bills.

Re-caulking is not only a great option for weatherproofing windows, but it can also be beneficial when weatherizing your front door. Over time, the caulking surrounding your windows will peel or wear away. Filling in empty spots each fall will help to seal your windows against any potential drafts. Additionally, it is fairly easy to do yourself!

Rigid Foam Insulation & Foil Stripping

To insulate your windows using rigid foam and foil stripping, there are some steps you will want to follow. The first is to use a hammer to remove moulding from around your window. Next, cut your foam to the right size to fit between the window jamb and wall. After spraying foam sealant into the empty space, insert the foam and cover it using adhesive-backed foil tape. Finally, replace the moulding around the window and—voilà! You are done!

Sometimes weatherproofing windows will only do so much to help improve your home’s energy efficiency. If your windows are outdated or beyond repair, it might be worth it to invest in windows that are high-quality and energy-efficient! Luckily for you, we have an extensive list of Ontario window companies that can help you.
