Fibrex® Windows: Frequently Asked Questions

At Renewal by Andersen® of Long Island, we proudly offer you one of the best replacement windows on the market. Our window frames are made of our patented Fibrex® material, which is known for being durable, strong and low-maintenance. In today’s post, we’ll address the most frequently asked questions we get about Fibrex windows.

What Is Fibrex?

Fibrex is a composite material made of reclaimed wood fiber and thermoplastic polymer. It provides you with the durability of wood coupled with the low-maintenance properties of vinyl. It is guaranteed not to blister, peel, fade or flake.

Why Use It?

It’s important to know that windows and doors boost your home’s energy efficiency. Our Fibrex material coupled with our High-Performance™ Low-E4® glass will improve your home’s insulation and further increase your home’s energy efficiency after a window installation job. Fibrex in itself is durable and requires less maintenance compared to other window options available on the market, which helps you save on maintenance costs in the long run. This is the same reason why we produce windows with narrower frames that don’t compromise on durability, resulting in a greater window surface area for a better view and natural lighting.

Is It Available for All Windows?

It certainly is. Our Fibrex® windows can be crafted in any style of your choice. This means that you can create double-hung, casement, bow and bay windows that are durable and stylish. Compared to fiberglass windows which can be only constructed in a straight line, our windows can be crafted into any shape which gives you limitless options. You can also pick different colors to match different themes in mind, whether it’s classic, modern, or traditional.

"I was very impressed with Renewal by Andersen. They showed up in time and we received several follow up phone calls as the installation was being done as well as the sales representative stopping by to check in on the installation. The delivery/ installer was very professional. I would highly recommend Renewal By Andersen."
