Why Vinyl and Wood Windows Warp

Why Vinyl and Wood Windows Warp

April 16, 2020

Replacement windows are a popular home improvement project. In many cases, the homeowner would like to get rid of outdated and non-insulating windows that came with the house built before energy-efficient options were available. In some cases, however, even modern windows can become candidates for replacement. One common problem is warping.

What Materials Warp?

The two most common window frame materials are wood and vinyl. Wood offers that timeless and classy look that many homeowners desire. Vinyl, on the other hand, is PVC or polyvinyl chloride plastic that became an alternative to wood and aluminum in the 1950s.

While wood is a favorite and vinyl is an energy-efficient alternative, these materials both have their own weaknesses. One of the weaknesses they share is warping.

Why Do Windows Warp?

There are two major reasons why wood and vinyl warp: exposure to excessive heat, and mishandling. Some other factors may contribute to these reasons. In areas that experience excessive heat, for example, there is a higher chance of warping in windows. This is truer if the windows are south-facing. If the wood or vinyl frame is black, it attracts even more heat. An awning or a casement window may have this problem if the material is wood or vinyl.

The more common reason for warping, however, is misuse. When you close the window and overtighten it, then the window is exposed to excessive heat during the day, the pressure that builds up can make the window bend. When a bent window cools down, it will never go back to its original form. As for wood, exposure to moisture and intense heat can lead to deformation as the material expands and contracts.

What Can I Do to Prevent Warping?

You can avoid overtightening the lock on your windows, but there is no assurance that a wood or vinyl window won’t warp. You can, however, think about replacing your windows with those made of better materials that don’t warp. A good example would be Fibrex, the proprietary material manufactured by Renewal by Andersen. Fibrex combines wood with composite so you can enjoy the best qualities of wood and vinyl minus their weaknesses, such as warping, cracking, peeling or fading. Fibrex is also more energy-efficient than either wood or vinyl.

Hear From Our Customers

Jason and Brett did an awesome job installing our doors. We had separate installers a month earlier for our windows who also did a fantastic job. They were all very professional and cleaned up almost better than the area looked before the installation! Since these were both jobs that took more than one day the installers were great at keeping us informed on the status of where the project was at along the way.

I cant express how happy we are with choosing Andersen for our window installation. Our sales representative was knowledgeable with product and answered any questions we had without hesitation. I did also fill out a survey that was sent in an email, but sadly I failed to personally name the two gentlemen that performed the actual installation. Barrett and Francisco were our guys, and let me tell you, they were outstanding!!! They did Excellent work and were professional as well as efficient and made this a smooth, none evasive process for us. I strongly recommend this company and these installers to anyone in need of windows!!! My husband and I could not be more pleased we chose Andersen for replacing our windows!!!

This was a great crew to work with. Both the original install manager we worked with (Jay) and the install team (Daniel, Mason, Tony, Ethan, and Jose). Everyone was very professional and knowledgable. They answered all my questions and the end result on the house is great. In 3 days they replaced an old bay window with a new bay window, a set of french doors on the patio with a sliding patio door, and our old front door with a new front door and storm door.
