Fibrex is Renewal by Andersen’s proprietary composite material used for stronger, more efficient, low maintenance window frames. Made from wood pulp and resin, Fibrex is used in every window made by Renewal by Andersen. If you’re unfamiliar with Fibrex and Renewal by Andersen products, knowing the benefits of this material can help you decide if Renewal by Andersen of Long Island is the right replacement window dealer and installer for your window replacement.

What Is Fibrex Composite Window Frame Material?

Fibrex is a composite wood material – meaning that it’s made of a combination of natural and synthetic materials. Because it includes actual wood fiber, Fibrex material can easily be made to look like other natural wood products. Fibrex composite material wears very well and is resistant to water damage and rot.

Renewal by Andersen of Long Island windows come in a range of colors, including a variety of natural wood grains like oak and maple. Its natural appearance and excellent durability make Fibrex a preferred product for thousands of installed window frames.

How Does Fibrex Compare to Natural Wood as a Window Frame Material?

Fibrex is similar to natural wood in the following ways:

  • Looks like wood. Unlike vinyl and other composite materials, Fibrex is difficult to distinguish from natural wood. That means you can have the durability of a synthetic, and the beauty of wood – all in one product.
  • Excellent insulation and energy efficiency. Natural wood is energy efficient – and so is Fibrex. This is because wood and composite wood both insulate better than many other window materials.

That said, there are many ways that Fibrex beats natural wood as a window material. For example, natural wood can be high-maintenance, especially as the wood gets older. Wood needs to be painted regularly. Before re-painting, the old paint needs to be scraped and sanded and any joints need to be caulked or filled. Wood needs to be cared for regularly or it can start to degrade as it is exposed to moisture from leaks and other problems.

Fibrex never rots or succumbs to mold and mildew like wood. In fact, this makes Fibrex one of the most durable window materials available. The only maintenance required for this window material is regular cleaning.

You’ll never have to repaint or restrain Fibrex, in order to maintain the window’s structural integrity. In this way, Fibrex material can actually last longer than natural wood, because Fibrex won’t break down if it’s not regularly protected from moisture.

Is Fibrex the Right Window Material for You?
