Fibrex®: The Better Window Frame Alternative to Wood

At Renewal by Andersen® of Milwaukee, we custom-manufacture replacement windows made from Fibrex®, our exclusive frame material for windows. In this post, we discuss how this composite material is made and how it compares to wood.

How It’s Made

Fibrex is made using real wood fibers and thermoplastic polymer. This unique blend of materials gives our frames the resilience and stability of natural wood bolstered with the low-maintenance properties of vinyl.

Durable and Resilient

Since it’s made with wood fibers, this composite material naturally resists expansion and contraction. Even when exposed to high heat and low temperatures, your Fibrex-framed windows, whether regular or specialty windows, won’t crack under severe temperature changes.

What sets our composite material apart is its high resilience to water damage. Wood, while naturally sturdy, will lose its luster and start decaying when constantly exposed to rainwater or moist conditions. Thanks to its low-maintenance properties, our Fibrex material is virtually immune to water damage. All it needs is a good cleaning to stay pristine.

Better Insulation

Fibrex also has superior thermal insulating properties, which further improve its natural tolerance to sudden temperature swings. This means you can request darker frames from us without fear of increased heat gain.

When paired with our High-Performance™ Low-E4® glass, our custom windows are highly energy-efficient. Your home will stay cool during summer and warmer during winter thanks to your new windows.

All these features give our Fibrex windows a longer service life compared to wood frame windows. With proper care and maintenance, your new windows will last as long as your home.

All of Renewal by Andersen’ windows, from the standard casement window to picture windows, are framed with the best window frame material ever made. Call us today at (262) 955-8400 for more information on our services. We install replacement windows in Milwaukee, WI.
