A Quick Comparison Between Fibrex® and Vinyl Windows

As you’re wondering which type of material you should choose for your window replacement, then you may be considering between vinyl or Fibrex®. While some homeowners may choose vinyl for energy-efficiency, thermal resistance and minimal maintenance requirements, you may not be aware of how Fibrex is actually the better option for your home.

How does Fibrex measure up to vinyl? Renewal by Andersen® of New Jersey gives a quick comparison.


Most modern windows are designed to resist the effects of wear and tear. This is especially important in climates that experience frequent temperature changes that can cause heat distortion and warp the frames as they expand and contract. Vinyl frames aren’t the most reliable when handling distortion due to heat exposure; they even expand twice as fast as Fibrex frames. Fibrex material is also already proven to tolerate higher temperatures.


With good insulation, a home’s energy efficiency greatly improves by maintaining a comfortable indoor temperature regardless of the temperature outside. While aluminum frame windows are commonly used in residential buildings, having either a vinyl or Fibrex window replacement offers far better energy efficiency.

Other Reasons Why You Should Choose Our Fibrex Windows

As a low-maintenance composite, our Fibrex windows hardly expand and contract, even in extreme temperatures. As such, we offer dark exterior colors that vinyl can’t because Fibrex® material won’t expand, even at temperatures of 150°F. And because it’s a composite material that uses real wood fiber, it’s very strong. This allows us to produce narrower frames, which simply means larger glass area. Meanwhile, vinyl frames are often thicker and therefore have a reduced glass area.
