The Problem of Warping in Wood and Vinyl Windows

Warping is one of the most common drawbacks of wood and vinyl windows. Apart from making frames look unsightly, this issue prevents the windows from performing effectively and efficiently. Why does it happen in the first place? Is there a warp-resistant alternative? We answer these questions and more here.

The Problem of Warping in Wood and Vinyl Windows

How Warping Occurs in Wood Windows

Wood windows are prone to warping, especially when exposed to water. Over time, the frames start to bend outward. It also happens when the material is exposed to extreme temperature changes that lead to expansion and contraction.

How Warping Occurs in Vinyl Windows

Prolonged exposure to heat can increase the chances of vinyl windows warping. This is even more so with temperature fluctuations that lead to the material expanding and contracting. Expect the vinyl components to soften up and become more malleable. Warping breaks the window seals and creates gaps, causing drafts to enter your home and compromise indoor comfort levels and energy efficiency.

Investing in Better Replacement Windows

Given the likelihood of warping in either wood or vinyl windows, it makes sense to invest in replacement windows that are equipped with better framing materials. One such example is Fibrex®, the exclusive composite framing material from Renewal by Andersen®.

Fibrex is composed of wood fibers and polymers that are combined during the extrusion process. The resulting material boasts the natural strength of wood and the insulating properties of vinyl, but without the disadvantages. Fibrex has a high resistance to rot, mold and decay compared to other conventional window materials in the market. More importantly, it doesn’t have high expansion and contraction rates, which means it is less likely to warp or bend when exposed to moisture or temperature changes.
