Does seeing a rainy or excessively humid day projected on the weather forecast elevate your level of concern for your home? It may be because the existing windows at your home do little to protect your home against the outdoor elements thanks to a poor seal with their window openings. This dilemma may place you in the market for replacement windows sooner than expected, yet it is a crucial investment nonetheless. During your search, you may have come across Fibrex® windows as a possible option for your home window replacement project. The sleek look of these replacement windows may serve as the perfect complement to your home’s existing aesthetic.

But before committing, you may be wondering if windows made with Fibrex® frames are waterproof. Fortunately for you, the answer is a resounding “yes”, thanks to their:

Nonporous Nature

Fibrex® is a proprietary composite material created by the innovative window manufacturer Renewal by Andersen®. Crafted from a 60/40 blend of thermoplastic polymer and reclaimed wood fiber by weight, respectively, Fibrex® stands as a viable alternative to windows made from natural wood. And since Fibrex® windows are nonporous, they do not absorb moisture, and therefore will not decay, rot, or otherwise deteriorate.

Structural Integrity

Consistently hot summers can have adverse effects on vinyl windows, as they are primarily comprised of plastic, which does not agree well with heat. With a composition that has been proven to be twice as strong and 12 times as thick as vinyl, Fibrex® does not warp and retains its rigidity much better than vinyl. What’s more, Fibrex® frames are designed to fit the window like a glove, creating a waterproof barrier, when shut.

Resistance to Thermal Contraction & Expansion

Many windows will contract and expand in response to extreme fluctuations in temperature, especially in areas of the country where the winters are frigid and the summers are sweltering. This can cause the seal between the windows and their openings to weaken over time, allowing drafts of air and even rain to seep in. Capable of withstanding temperatures as high as 150 degrees, Fibrex® windows don’t expand or contract, allowing them to maintain a weathertight seal and keep water from infiltrating the home.
