As the temperatures outside drop to astonishing lows, you want to be able to stay warm and comfortable in your home. Unfortunately, air leaks are a common problem for many homeowners. Have you ever walked into a room and suddenly felt a chill? Or been sitting by a window and notice that it is several degrees cooler? These are fairly common problems and most often they stem from leaky windows. In fact, windows are often the weakest link in your exterior envelope. You could be losing around 11% of your heating right out the window. But why are windows so drafty? Here are just a few reasons:

1. Age

This is the leading factor. As windows get older, the seals and other components break down. So not only do windows become more difficult to operate with age, but they also become less efficient. If your windows are more than twenty years old, it is probably time to start considering replacements.

2. Installation

Another leading factor in windows leaks is poor installation. Some homeowners choose to install windows themselves or hire a general contractor in an effort to save money. And while window installation looks easy, it takes precision, proper tools, and a lot of know-how. Even the smallest margin of error and you end up with window leaks or other problems. This is definitely one of the home renovation projects best left to trained professionals.

3. Glass Panes

Double pane windows are a common feature in most homes and have been for some time. With tight seals and inert gas fills, you can significantly reduce heat transfer and air leaks in your home. But if you get condensation forming between the panes on your window, it means the seals have failed and water vapor is getting between the glass. This significantly reduces the energy efficiency of your windows and can contribute to convection currents near the glass that feel like drafts.

4. Moisture Damage

Water is good for a lot of things, but not when it comes to most window parts. If too much water leaks down into the frame, it can cause some damage, leading to poor window performance. So if you notice warping or discoloration from water infiltration, make sure it is addressed so it does not contribute to drafts.

Do you have drafty windows? Sometimes repairing or replacing the weather stripping or caulking may help. If not, consider replacing older windows with new energy-efficient models.
