FAQs About Fibrex® 

1. What Is the Fibrex Material?

The Fibrex is a patented composite material that Andersen® Corporation has designed, developed and incorporated into our Renewal by Andersen products. A blend of 40% reclaimed wood fiber and 60% thermoplastic polymer, most of which are also reclaimed, it combines the strength and stability of wood with the low-maintenance features of vinyl. It offers superior benefits in terms of insulating properties, resistance to decay, structural rigidity and more, making it an excellent choice for your replacement windows.

2. Do Fibrex Products Come With Warranties?

Renewal by Andersen of Nashville believes that replacement windows are a perfect combination of top-quality materials, including glass and frame, and excellent installation. This is why we make sure to back our products with our impressive 20/2/10 Limited Warranty, which is recognized as one of the best in the business.

3. Is Fibrex Available for All Windows?

The Fibrex material can be incorporated into all styles of windows, from awning and casement windows to picture and sliding windows. Moreover, the Fibrex material can also be used for specialty and curved windows, unlike the conventional fiberglass material that only allows for straight lines.

Benefits of the Fibrex Material

1. Strength

Due to the inherent strength of our Fibrex material, we are able to create narrower frames and sash, which translates into an expansive glass area and increased views. Meanwhile, run-of-the-mill vinyl frames tend to have a higher expansion and contraction rate, and can bow, often resulting in distorted, fogged-up views and broken glass seals.

2. Insulation

The Fibrex material is well-known for its excellent thermal insulating properties. Thermal insulation improves comfort by maintaining indoor temperatures. This means the innovative framing support, especially when combined with Andersen High-Performance™ Low-E4® glass, can help keep your home toasty and pleasant during the winter months, and cool and refreshing in the summer season. You can also save more money on heating and cooling costs throughout the year.

Aluminum frames, on the other hand, have the highest thermal conductivity, a measure of a material’s ability to transfer heat. Much needed heat can leak out of your house during cold, freezing winter and into your house during scorching summer. Replacement doors and windows with lower thermal conductivity are better on windows because they conduct less heat energy.

3. Low Maintenance

One of the main reasons why homeowners choose Fibrex windows is because they only require minimal maintenance over the course of their life. The composite material will not need scraping or repainting. It is also resistant to rot, mold and decay, meaning it will remain strong and stable over time as opposed to fiberglass frames that may need to be repainted and frequently maintained. In fact, Fibrex windows are backed by a warranty not to rust, peel, blister, flake, crack or corrode. This particular benefit is due to a special polymer formulation that coats each wood fiber during the manufacturing process.

4. Stable and Predictable

Compared to vinyl, the Fibrex material is twice as rigid and stable. While the average stiffness of wood is higher, it is less predictable than the composite material because of the natural variations of wood, knots and moisture content.

5. Beauty

Renewal by Andresen replacement windows enhances the architectural appeal of your home. The unique pressed-out Fibrex material can be constructed into any style of window, from traditional windows to customized, specialty windows, and in colors that complement every home. Furthermore, the sash and frame design can reflect the shapes and lines of your original windows. 

Most window replacement units on the market feature a square profile that may look artificial when installed in your home. Vinyl-framed windows are also usually thicker, reducing the glass area, while the fiberglass material, as previously mentioned, can only be manufactured into straight lines.

6. Environmental Responsibility 

Since 40% of the raw material by weight used to create the Fibrex composite material is clean, reclaimed wood fiber, Renewal by Andersen windows are ENERGY STAR®-certified for meeting strict energy performance standards set by the U.S. Department of Energy. In the manufacturing process, reclaimed materials can also be reground and reused. Meanwhile, with a straight and flat piece of fiberglass, you cannot make abrupt modifications in shape, although the contour can be varied.

Reasons to Replace Your Windows

1. Increased Home Value

Replacing your old, shabby windows can have a significant payoff. New windows can return over 70% of the total cost of the project upon resale. Moreover, it is possible for prospective buyers to turn away if the windows in a home are in need of repair or replacement. 

2. Enhanced Security and Safety

Windows that do not operate properly can pose a safety hazard, especially when you are escaping during a fire emergency. New window replacement units will not only provide healthy, fresh airflow, but the improved performance and functionality can also benefit the residents as well. From up-to-date locks and security sensors, homeowners can receive additional protection and peace of mind while at home.

3. Improved Home Comfort

By installing energy-efficient, well-sealed windows, you can reduce cold drafts and hot spots in your home. Dual- or triple-pane windows are good at preventing heat transfer and minimizing the amount of ultraviolet (UV) light that enters your living space. Moreover, updated windows can keep the climate-controlled air in, allowing you to relish in a safe, consistently pleasant environment, which ultimately results in lower energy bills.

4. Reduced Outdoor Noise

It is no secret that noise pollution can be harmful to your health and well-being. Fortunately, modern replacement windows help block out various noises and provide a more restful living space. Features like insulated frames and triple-pane glass can minimize, if not eliminate, noise from traffic, lawnmowers, beeping vehicles and barking dogs. This reduces naptime interruptions and provides more peace and quiet for the residents.

5. Enhanced Curb Appeal

There is no doubt that new windows can dramatically improve the beauty of your home. Replacement windows are available in a range of sizes, colors and finishes that coordinate with the personal character and style of your home. An updated exterior will also enhance the curb appeal and resale value of your home.
