What Causes Wood and Vinyl Windows to Warp?

Windows make your home beautiful from the inside out. They offer superior weather protection and help illuminate your living space. Like other parts of your house, they will eventually need to be replaced. When it’s time for a window replacement, you must choose the right material to make the most of your investment.  

While wood and vinyl are popular window materials, they are prone to warping. Keep reading to find out what causes this issue. 

What Causes Windows to Warp?

Warping is a common issue in vinyl and wood windows, causing bowing, bending, cupping and other deformities. Over time, the problem will worsen and start affecting your home’s curb appeal. Excessive moisture is the most typical reason windows warp.

Uneven absorption of moisture in your windows can cause stress. As a result, the window frame will expand and contract. The longer the exposure to moisture, the more lasting the effects of expansion and contraction will be. Temperature changes can also contribute to this issue. 

Moreover, dark-colored vinyl tends to absorb more heat from the sun. Windows on the southern part of a home receive more sun, making them more likely to warp. However, the sun alone can’t cause severe damage to your windows. It’s a combination of different factors such as airflow, finishing, grain orientation and temperature.
