Vinyl Vs. Fibrex® Window Frames: A Quick Comparison

Vinyl is a material often associated with energy-efficient replacement windows. Its thermal resistance, minimal upkeep and overall cost efficiency are some of the notable qualities that have drawn many homeowners to it. Today, however, there’s an even better option called Fibrex®, the exclusive framing material from Renewal by Andersen®. Here’s a quick comparison between the two.


The local climate is one of the many factors that should be considered when choosing replacement windows. They should be able to withstand the damaging effects of wear and tear, especially if the climate involves frequent changes in temperature. Vinyl frames tend to have a high expansion and contraction rate, which means they can warp and bow when exposed to extreme heat and cold. Fibrex, meanwhile, can tolerate such conditions without breaking the glass seal.


Windows with a high level of insulation help improve the energy efficiency of your home by maintaining comfortable indoor temperatures regardless of the same outside. Both Fibrex and vinyl offer superior thermal insulating properties compared to aluminum frames.

Aesthetic Appeal

Most replacement windows and doors have profiles that may look artificial in your home. Vinyl-framed windows, for one, are usually thicker, which means a smaller glass area. Fibrex, however, is a strong, durable material that can be extruded to make sashes and frames narrower, resulting in more glass and a better outdoor view. The same extrusion process allows the windows to be shaped with curves and lines, preserving the home’s architectural beauty.


Fibrex is a more sustainable option than vinyl. About 40% of the material is reclaimed wood fibers that are repurposed from Andersen Corporation’s wood window manufacturing. This means that Renewal by Andersen is doing its part in reducing waste that ends up in landfills.
