Two of the most popular window materials are wood and vinyl. They go well with different architectural styles, regardless if you have a modern or classic-looking home. Despite the appeal and versatility of these materials, their sashes tend to warp.
One of the area’s leading window companies shares what usually causes this issue.
Warping is when wood and vinyl windows start to change in appearance until they are deformed. Over time, holes and cracks will develop, affecting the windows’ appeal and thermal performance. Some of the most common types of window warping include bowing, cupping, twisting, crooking and kinking.
Excessive moisture is usually to blame for warped wood windows. The material can easily absorb and hold on to moisture, resulting in issues like warping, rotting and mold. When these windows absorb moisture unevenly, they create stress that contributes to expansion and contraction. The longer the problem persists, the more unsightly the units will look.
Heat is typically the suspect behind warped vinyl windows. Extremely high temperatures can cause these windows to twist, bow, soften and warp. They can also sag because of how flexible they are. Another problem with these windows is that they can fade over time when exposed to harsh outdoor conditions and weather.
