Drafty windows can be a major source of discomfort and energy loss in a home. Not only can they make a room feel chilly and uncomfortable, but they can also drive up your energy bills by letting in cold air during the winter months. If you suspect that your windows are drafty, it is important to identify the source of the draft so that you can take steps to address the problem. In this article, we will discuss some methods for detecting drafty windows.
- Check for air leaks: The first step in detecting drafty windows is to check for air leaks. You can do this by holding a lit candle or incense stick near the window frame and moving it around the perimeter of the window. If the flame or smoke wavers, this is a sign that air is leaking through the window. You can also use a damp hand to feel for cold spots around the window frame.
- Use a thermal imaging camera: A thermal imaging camera can help you identify areas where heat is escaping from your windows. These cameras detect infrared radiation, which is emitted by objects based on their temperature. By using a thermal imaging camera, you can identify areas where the temperature is lower than the surrounding area, indicating a draft.
- Conduct a smoke test: Another way to detect drafts is to conduct a smoke test. Simply light a stick of incense and hold it near the window frame. If the smoke blows away from the window, this indicates that there is a draft.
- Check for visible gaps or cracks: Sometimes, the source of the draft is visible. Check the window frame and the area around it for visible gaps or cracks. These can occur due to wear and tear, poor installation, or damage to the window frame. If you identify any gaps or cracks, you can seal them with weatherstripping or caulk.
- Conduct a professional energy audit: If you are having trouble identifying the source of the draft, you may want to consider hiring a professional to conduct an energy audit. An energy auditor can use specialized tools to detect drafts and provide recommendations for how to address the problem.
In conclusion, detecting drafty windows is an important step in improving the comfort and energy efficiency of your home. By using these methods, you can identify the source of the draft and take steps to address the problem, such as sealing gaps and cracks or replacing the window.
