Windows that are not regularly maintained are more likely to experience serious problems, like warping. Once your windows have twisted out of shape, they can create large gaps and decrease your home’s energy efficiency.

To help you identify the source of the problem, here are the common causes of window warping.
Moisture
Typically, warping occurs in wood windows. When moisture is unevenly absorbed into the grain of the wood, it causes the material to expand and shrink. These movements can eventually lead to warping and rotting. The best way to solve this problem is to eliminate moisture around your windows.
Temperature
Fluctuating temperatures cause wood windows to expand and contract. Over time, this thermal movement can cause the window material to bend or become deformed. To address this issue with a long-term solution, use Fibrex® windows. Made of composite framing materials, these windows offer excellent performance, improved energy efficiency and lower environmental impact.
Other Minor Causes
There are other several factors that can cause your windows to warp. These include window orientation, sunlight, ventilation, finishing and temperature. However, take note that even if you don’t have any problem with the causes mentioned, wood windows that are constantly exposed to moisture will warp. Regular inspection and maintenance can help keep your windows in tip-top shape. In case of minor issues, your window contractor will be able to detect and address the culprit right away before it becomes a bigger problem.
