Fibrex® vs. Aluminum Windows: Which is the Better Option for Your Home?

Fibrex® vs. Aluminum Windows: Which isA perfect neighborhood. Houses in suburb at Summer in the north America. Fragment of a luxury house with nice window over blue sky. the Better Option for Your Home?

Opting to replace your house windows is no trivial investment. In order to ensure you won’t have to endure this process again for some time, it’s best to choose replacement windows that are of the highest quality. Two options you may have come across during your search are aluminum windows and Fibrex® windows. But which of the two best meets your criteria? Consider how both window options stack up in terms of:

Energy Efficiency

Aluminum is a material with an inherently high conductivity, which means it easily retains the heat and cold. Aluminum windows, therefore, are probably not the best option if you’re looking to reduce cooling and heating costs. Fibrex®, on the other hand, is a proprietary composite material produced by leading manufacturer Renewal by Andersen® that boasts some of the most impressive insulative properties you’ll find in a replacement window. In fact, Fibrex® windows have been proven to insulate up to 700 times better than aluminum windows. What’s more, thanks to energy-efficient features such as High-Performance™ Low-E4® glass and seamless weatherstripping, Fibrex® windows have earned impressive ratings from both ENERGY STAR® and the NFRC.


Although aluminum generally is a durable material, it is not exempt from deterioration. When aluminum is exposed to salt in the air or water over an extended period of time, it begins to corrode, which is a potential issue you may encounter when you opt for aluminum windows. Conversely, Fibrex® are composed of a 40/60 blend of reclaimed wood fibers and thermoplastic polymer, respectively, making these composite windows impervious to not only corrosion, but also warping, rotting, and other forms of decay.

Ease of Maintenance

When exposed to the sun, anodized aluminum can develop discolored spots—also known as oxidation. In order to keep aluminum windows from discoloring, they require consistent cleaning with a solution made up of water and vinegar. But if you’re like many other busy homeowners who don’t have the time to dedicate to cleaning their windows on a regular basis, Fibrex® windows may be the way to go. These replacement windows are crafted using a unique fabrication process in which each attractive color is infused into the Fibrex® material, providing a stunning aesthetic that will last for years on end. And because Fibrex® windows won’t flake, peel, or pit, you won’t have to worry about staining or painting them down the road.
