You may keep your home at a comfortable temperature using your heating system, but when you walk past certain windows in the winter, you may consistently feel a chill. This pocket of cold air is basically a draft coming from the window, usually due to failing weather stripping or seals.
These defects tend to appear around the window frame’s outside edge as the frame and glass meet. They can also happen anywhere that panes of glass open, move or overlap. Take a gliding window, for instance, where the sash is vulnerable to draft development. If you have a draft around your windows, here are some likely reasons why.
Wear and Tear
Most high-quality windows will last for decades, but normal wear and tear can certainly take a toll. The common failure is weather stripping which becomes compacted, worn or twisted.
Aging Windows and Frames
Your window panes and frames are impacted with age. Wooden frames, for example, tend to crack or warp over time, leaving small gaps that allow cold air to get in. Are your windows more than 20 years old? Not even sure? Have a professional inspect your windows for structural integrity to see if age is to blame with your drafty window.
Extreme Outdoor Temperature Changes
In cheaper windows, drafts can be caused by temperature changes. That’s because certain materials tend to expand when they are warm and then contract when they are cold. This contraction lets cold outside air into your home.
High Moisture Levels
Do you live in a humid climate or in a place that gets a lot of rainfall? When windows are exposed to a lot of moisture, there’s a better chance of water getting under the seal and breaking it, allowing moisture and cold air to get in. If you see condensation on your windows, wipe it with a dry cloth to reduce the risk of water damage.
Lack of Maintenance
Weatherstripping requires a small amount of maintenance. If you neglect this cleaning maintenance, the weather stripping can be exposed to corrosive chemicals. Be sure to follow instructions set forth by your window contractor and manufacturer and keep up with a proper maintenance schedule.
If your windows were not installed correctly in the first place by a reputable professional, a weakness may be present in the seal, particularly around the outside of the frame. Always hire an experienced and trusted contractor to install your windows, to reduce the chances of drafts later on.
