Today, we answer frequently asked questions about Fibrex.

1. Why Use Fibrex®?

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 help improve your home’s insulation and further increase your home’s energy efficiency. Fibrex is our popular and revolutionary material that has the durability of wood with low-maintenance properties of vinyl. To achieve this, we’ve combined reclaimed wood fibers with our own thermoplastic polymer. This allows Fibrex to resist cracking, bowing and decay even when exposed to fluctuating temperatures, making it an excellent and reliable material to work with.

2. Is Fibrex 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 casement, bow, bay and double hung replacement 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, whether it’s classic, modern or traditional.

3. How Can Fibrex Help You Save On Your Energy Bills?

Our Fibrex material frames have inherent insulation, which means they do not require a foam or similarly insulating core. Combined with our High-Performance™ Low-E4® glass, Renewal by Andersen replacement windows prevent heat from leaking between your indoor and outdoor spaces, which can help reduce your home’s indoor heating and cooling requirements, leading to energy savings. Each Renewal by Andersen replacement window is certified by ENERGY STAR®.

4. Is Fibrex Eco-friendly?
