Vinyl Windows: Exposing Their Biggest Problems

A newly installed vinyl window looks good and functions well, as is the case with a variety of window materials. A few years in, however, and it begins to manifest problems that can affect its performance and longevity. It may be affordable compared to other materials like aluminum or fiberglass, but it doesn’t always provide you the best overall value.

Renewal by Andersen® of Rapid City, your local source of home replacement windows, discusses the biggest problems associated with vinyl windows.


Vinyl windows are available in a variety of colors. Most of the time, however, they don’t last long. Exposure to the sun’s ultraviolet and infrared rays causes the color to fade, effectively losing their appeal.

Expansion and Contraction

Certain climates experience fluctuations in temperature, which can affect vinyl windows. Expansion and contraction happen because of this, resulting in the broken air seals and warped frames and sashes. Gaps form because of this, compromising the home’s comfort levels and energy efficiency.


The problem of expansion and contraction in vinyl windows just proves that the material is not capable of withstanding heat. Sagging may occur when the frame material is exposed to temperatures as high as 160°F. This issue can detract from the entire aesthetic appeal of the home.

A Better Alternative

Given all these problems in vinyl windows, you will be making a great decision if you decide to choose better alternatives for your casement window replacement project. One of them is Fibrex®, Renewal by Andersen® patented composite material.

One of the best things about Fibrex is that it has the same features as vinyl windows but without the disadvantages mentioned. Apparently, it is all in how the material is engineered into the replacement window units.

It has a combination of wood fibers and polymer, creating a composite that gives Renewal by Andersen windows their rigidity and stability. A 20-year study by the window company proved that they can stay in great condition since their original installation. It means that they can stand up against the various elements. Even when exposed to sunlight, they are guaranteed not to fade, chip, rot, or corrode.

"We recently replaced all of the windows in our home. I was most impressed with the friendly staff who knew what I wanted before I did. They seemed to be able to find the perfect window for each one we replaced. We are very pleased with the result. From beginning to end they were professional and helpful. I would highly recommend Renewal by Anderson."
