Looking to switch energy?

As the winter months descend upon Canada, bringing extreme cold weather, homeowners face the challenge of keeping their homes warm without skyrocketing heating costs. A common issue during the winter season is window condensation, which can be both inconvenient and indicative of energy inefficiencies within your home. In this post, we’ll explore strategies to prevent window freezing and to ensure your home remains cozy and energy-efficient throughout the coldest months.

Understanding Frozen Windows

Window condensationFrozen windows occur when moisture in the air inside your home comes into contact with a cold windowpane, causing condensation that subsequently freezes. This can happen due to inadequate window insulation or temperature imbalances between the inside and outside of your home.

Preventing Frozen Windows: Tips and Strategies

Enhance Window Insulation: One of the primary steps in preventing window freezing is to improve window insulation. This can involve installing weather-stripping, using thermal curtains, or applying insulating window film. Such measures not only prevent freezing but also contribute to overall energy efficiency.

Seal Gaps and Leaks: Examine your windows for any gaps or leaks that can allow cold air to enter and warm air to escape. Sealing these with caulking or weather-stripping can make a significant difference.
