Wood vs Composite Window FrameReplacement Window Frames

The starting point for designing your replacement windows should be considering the framing material that surrounds and houses the glass panes. Two of the most popular window framing materials on the market today are wood and composite materials.

What Are ‘Composite’ Windows?

We all know what wood windows are; they’ve been around and performed well for centuries, but what exactly are composite window frames? Composite materials are simply the mixing of two or more distinct materials to create a better product that leverages the best characteristics of each individual material. The end result is a stronger, more versatile, and often more beautiful material that requires less maintenance than the individual ingredients.

Renewal By Andersen’s Fibrex Composite

Fibrex, is a composite material created by Andersen Windows’ team of scientists does just that. Using the light weight, water repellent characteristics of PVC and the strength of wood, Fibrex, delivers a construction material that is far superior to vinyl or aluminum with the stability and low-heat transfer of wood.

Wood Window Frames and Composite Window Frames

Composite Window Frame BenefitsBefore you decide on the colors, options and finished of your windows, let’s compare Fibrex windows with traditional wood windows. Being manufactured largely of wood, Fibrex responds to changes in weather similar to the wood framing or brick exterior of your home. Fibrex is stable like wood and doesn’t have the extreme expansion and contraction issues of some other materials (like vinyl). This means that you will not have to deal with gaps caused by the natural contraction and expansion of your home as the temperature rises and falls throughout the seasons.

Fibrex is Weather Resistant

However, Fibrex, by mixing the wood with PVC, eliminates the natural tendency of wood to absorb water, swell and rot like wood. You won’t have to worry about termites eating your Fibrex window frames!

Structurally Sound

Another similarity between wood and Fibrex is that both are structurally strong. Fibrex is stronger than wood, but both maintain their shape and easily support the weight of even the heaviest glass in the extreme heat of the summer, nor to they become brittle in the frigid cold of winter.

Fibrex is Low Maintenance

One significant benefit of Fibrex over wood as a window frame material is its low-maintenance factor. Fibrex is  impermeable – it does not absorb water like wood. For you, that means no worries about flaking paint from moisture during the rain and snow seasons and no rot to deal with as it dries out. Wood requires routine maintenance to protect it from the elements and potential threats like termites and other wood destroying insects.

Fibrex is Good for the Environment

If protecting the environment is important to you and your family, you will be glad to know that Renewal by Andersen shares your values.
