Why Vinyl Windows Warp

Choosing ENERGY STAR® windows is the best way to maximize the benefits of your window replacement project. Aside from this, frame material also plays an important role in determining the performance of your windows. This is where vinyl greatly outshines its wooden predecessors. Vinyl windows come with a lot of advantages and none of the drawbacks that wooden and aluminum windows have.

Vinyl Windows Warp

Unfortunately, vinyl is not without its disadvantages. There is one problem, in particular, that’s unique to vinyl windows and can affect the way it looks as well as the way it performs: warping. Here is a primer from our experts at Renewal by Andersen® of Memphis on warping vinyl windows and what you can do to avoid this happening.

Why Vinyl Warps

Vinyl is a highly durable plastic material used to frame highly energy-efficient windows. Its chemical composition is similar to regular plastic with key differences that mainly add to its strength and heat resistance. However, age and exposure slowly degrades this durability, causing the windows to warp under direct sunlight.

Why Warping Is a Problem

When a vinyl replacement window warps, the size and shape of the frames, sashes and jambs can change. This poses problems on how the window operates. In a sliding window, the frame itself can cause the tracks to be off-kilter, causing issues with the sliding mechanism. Casement and double-hung windows also face the same problems with warping.

What Can You Do About Warping

Many window installation companies and manufacturers have tried to solve the warping problem of vinyl but Renewal by Andersen offers the best alternative in Fibrex®. Fibrex is an exclusive material made with a high-quality thermoplastic polymer and reclaimed wood chips to combat warping. As a frame material, it offers all the aesthetic value of traditional wooden windows and the enhanced warp-resistant strength of vinyl.

"Absolutely wonderful experience working with renewal. They kept my wife and I up to date all throughout the process from the initial sales pitch to installation. They were courteous and professional throughout. The installation of 8 windows was completed in one day and the product is fantastic. Immediate difference felt inside the home and its much quieter now too. My wife and I are thrilled at our purchase. The windows are a bit pricey but worth every single penny. Wonderful product from a wonderful company. Will definitely be using them in the future to install the rest of the windows in our home."

"When I say, superior service I mean just that!! From start to finish I was pleased!! Step 1, Scheduled appointment at the Home show… easy. Step 2, phone call to confirm appointment the next week….easy. Step 3, in home consultation with Keith Billingsley…..Amazing!!!! Step 4, call and cancel all other Window companies and let them know you have chosen the Best company, Anderson Windows!!! My Windows took a couple of months to come which was not a problem. Oooohhh but when installing day came ( a week early) I was lost for words. The installation team was A1 with professionalism and cleanliness!! They didn’t leave a scrap of trash on my property. It was cleaned up both days. I had Ed Tutton and crew. I had a million questions and they answered every one of them and made me feel so assured with the process. A couple of my Windows had wood rotted. They took care of it and fixed it better than when the house was built!!! Two of my Windows came in broken, it was addressed and shown to us and reorder in the same day!! They will be installed later. The Windows are so beautiful I stood in my master bedroom Windows for almost 3 hours just looking out. I hate Window grates…. I have solid glass Windows now❤️❤️! I wish I would have ordered my new front doors from Anderson Windows. So if you are looking to get new Windows you must go with Anderson Windows!!!"
