Preventing Frost on Windows

If you’re noticing frost on your windows, it can seem like no big deal. But frost-coated windows can eventually begin to impact the comfort and warmth of your home. To help keep your windows frost-free, here are some recommended methods to try for preventing frost on windows.

Why Does Frost Form?

Before using any preventative methods, let’s first explain why frost usually forms on your windows. When there’s moisture present in your home, it can latch on to your windowpanes. Once that water vapour that’s lingering in the air hits a cold surface from the icy temperature outside, it forms frost.

Another common reason is having old windows that are poorly insulated. So if you’ve had your windows for many years, it could be time to consider replacing them.

Turn On Exhaust Fan When Cooking

If you’re cooking up dinner, boiling water for tea, taking a hot shower or doing anything that expels steam, flip on the exhaust fan to draw out that excess moisture from the air. This will improve the ventilation in your home. Just be sure that the exhaust is directing the air outside.

Use A Dehumidifier

If your windows are really frosting up, then it might be worthwhile to use a dehumidifier. Although the air in most homes tends to become excessively dry during winter, your home might just be a favourable environment for trapping in water vapour. If your house is too humid or you notice frost forming during particular times of the day, flip it on until you notice the frost dissipating.

Make Sure Joints Are Sealed

Using rope caulk is another alternative that can be effective at preventing frost on windows. Simply apply it along the joints of the frame during the winter and then remove it in the spring.

Upgrade Your Windows

If your windows are old and dated, they most likely have low thermal performance. Old single and double pane windows can often allow too much interior heat to percolate outside. With poorly insulated windows against the cold air, frost can become a nuisance, which can eventually lead to mold if it lingers along wooden frames. Upgrading might be your best option. New window designs have higher thermal performance and better insulation to keep the heat inside and the cold air outside.

If your windows are old and worn, they’re most likely the cause of your frost build up. The combination of poor insulation and excessive moisture in your home are what make those magical, yet irritating condensation crystals form along the glass.
