The Biggest Drawbacks of Vinyl Windows

Vinyl continues to be the top window material of choice for many homeowners. Despite its advantages like affordability and beauty, it has its share of drawbacks that often manifest after the windows are purchased and installed.

Fibrex as warp-resistant solution

Warping in the Window Frames

Warping on vinyl window frames is more than just an eyesore; it prevents the window from performing as intended. When exposed to heat, the material may soften, warp, twist and bow. This particular problem doesn’t just affect your home’s aesthetic appeal, but also leaves gaps, compromising indoor comfort and energy efficiency.

Expansion and Contraction

Climate also plays a role in the vinyl windows’ long-term performance. Temperature fluctuations can cause the material to expand and contract, which then break the seals around the window glass and warp the frames and sashes. Window installation pros can look at the issue and recommend whether to repair damaged parts or replace the whole window entirely.

Discoloration

Despite the beauty that vinyl windows lend to homes, the material tends to discolor over time, especially when subjected to extreme weather conditions. Exposure to the sun’s ultraviolet (UV) and infrared rays can cause the color to fade.

Choosing a Better Alternative

These disadvantages can be avoided by selecting a better window material alternative. Fibrex®, a composite window material patented by Renewal by Andersen®, is one of them. It has the same qualities as vinyl windows, but with the natural beauty and rigidity of wood windows. Windows with this material are engineered to withstand a variety of elements.

Reviews

"Have nothing but great things to say about the window installation done today by John Hutchinson with Renewal by Andersen! He was friendly, personable and professional and did a great job installing. He did a great job of putting down roller pads and tarps with next to zero clean up. Would highly recommend them for any window replacement needed!"

"We had our new Renewal by Andersen windows installed on June 5th & 6th, 2025 and we LOVE them! The quality, beauty, and functionality are best-in-class! The whole experience from dinner presentation at Lazy River Grill, the initial in-home sales consultation and measurement, the regular communications from the salesman and concierge, and the installation team’s professionalism and skills made the process so seamless. This is the second home we have opted for Renewal windows and doors and have been delighted both times! Thank you Renewal by Andersen STL! "

"I had an excellent experience with RbA STL. Our designer, Courtney, was great and the finished product is awesome. The installation was easy and the gentlemen left our home cleaner than they found it upon entering. I would recommend RbA STL - you’ll get tired from their constant contacts, and that’s a GOOD thing!"
