    Fibrex®: The Answer to Warping Problems in Windows

    Warping in windows, particularly those made of vinyl or wood, occur when the frames aren’t built to handle excessive heat. It compromises the windows’ structural integrity as well as affects your home’s energy efficiency due to the large gaps it creates. It usually comes in many forms; bowing and crooking, for instance, are characterized by bending along the face and edge of the window, respectively. Cupping happens when the framing warps inward or outward.

    Installing Fibrex windows

    As the leading window installation contractor in the area, we are fully aware of this issue in many windows, which is why we offer an alternative for homeowners. Fibrex®, our company’s exclusive framing material, is impervious to warping. We explain why below:

    Composite Material

    Fibrex combines the strength and stability of natural wood with the ease and simplicity of vinyl. During manufacturing, thermoplastic polymers are used to fill and surround individual wood fibers, creating a composite material that remains strong over time and withstand the damaging effects of moisture. The durability of Fibrex allows us to create thinner frames and utilize larger glass panes.

    Guaranteed Not to Deform

    Choosing Fibrex windows for your window installation project allows you to take advantage of the Renewal by Andersen® comprehensive warranties. One of them covers defects on the composite material’s components, including flaking, blistering, cracking and warping. Fibrex doesn’t need to be painted or scraped, and will remain in good condition even with minimal upkeep.

    Engineered to Withstand Weather Extremes

    A study of Fibrex frames showed no signs of cracking, chipping and peeling even after 20 years. Even with temperature swings, the frames and sashes didn’t display signs of expansion and contraction. Because of this, the windows continue to operate with ease years after installation.
