What Makes Renewal by Andersen® Different?
We are proud to announce that Norton's Quality Exteriors has been selected to be your exclusive Renewal by Andersen replacment window dealer!
Patented Fibrex® frames
Renewal by Andersen® replacement windows are made from Andersen's exclusive Fibrex® material. This breakthrough composite combines the strength and stability of wood with the low-maintenance features of vinyl.
Key benefits of Fibrex® material:
- Slim, sleek profiles allow more glass area
- Available in 22 standard color options
- Stainable wood interiors available, including oak and maple
- Excellent insulator preventing heat or cold transfer into or out of your home.
- Resistant to changes in temperature
- Low maintenance: no need to scrape or paint again Warranted not to flake, blister, peel, pit or corrode.*

Along with color, design and lifestyle benefits, the environmental benefits of how we make Fibrex material led to Andersen Corporation becoming the first and only Green Seal Certified window manufacturer. All of the wood fibers used in the compounding process, as well as some of the thermoplastic polymer, are reclaimed directly from the 65-acre Andersen Corporation manufacturing plant operations in Bayport, Minnesota.

Energy Efficiency / Lasting Beauty
Energy Tax Credit
Renewal by Andersen® windows and patio doors with High-Performance™ Low-E4™ glass can reduce energy bills by 25% in the summer and 10% in the winter*. Better yet, if you buy them now, most will qualify for a credit of up to $500 on your federal income tax. Click here for more details.
Energy Efficient Windows
Poor-performing windows can lose up to 40 percent* of heating energy in winter. With the high cost of energy, that's a lot of money going right out the window! Even worse (and often overlooked), poor-performing windows can lose up to 50 percent* of a home's cooling energy in summer. It's expensive to have worn-out or inefficient windows.

Shopping for energy efficient replacement windows can be confusing, but an important factor to keep in mind is whole window performance. Renewal by Andersen's outstanding whole window performance is the result of our patented Fibrex® framing material, Andersen High-Performance™ Low-E4™ double pane glass, and professional installation.
Together, these elements will keep your home 35% more energy efficient in winter and 41% more efficient in summer*. Depending on where you live, that can cut your energy bills by up to 25%**
What's the easiest and most accurate way to compare the energy efficiency of windows? Be sure the window displays an NFRC label. This label means the entire window unit has been tested, not just the center of the glass or part of the frame. The U-Factor is a better indicator of window performance than R-value. The lower the U-Factor the better the insulation properties.

High Performance™ Low-E4™ Glass

Renewal by Andersen introduces High-PerformanceTM Low-E4TM Glass, the next generation of energy-efficient, low-maintenance glass, and further advances Andersen's proven glass technology.
Fewer Water Spots and Easier Cleaning
New Low-E4 glass features an innovative titanium dioxide (TiO²) exterior coating, which makes cleaning easier. When this coating is activated by sunlight, dirt loosens from the glass and can be washed away by rain. The special TiO² coating also makes the glass dry faster with up to 99% fewer water spots*.
Adds Thermal Protection
Andersen Low-E4 glass employs a hermetically-sealed system for optimum insulation from heat, cold and sound. A patented low-conductivity spacer separates the two panes of glass. The space between the two panes is filled with an argon gas blend to minimize the thermal transfer. Compared to ordinary dual-pane glass, High-Performance Low-E4 glass is 41% more energy-efficient in summer and 35% more efficient in winter. Depending on where you live, that can cut your energy bills up to 25%**.
Helps Keep UV Rays Outside
High-Performance Low-E4 glass works like a sunblock to filter ultraviolet (UV) rays that can fade fabric and damage furniture. Ordinary dual-pane glass lets 63% of UV light pass through. High-Performance Low-E4 glass is layered with 11 microscopic coatings that cut UV transmission down to 17% with virtually no effect on the clarity or color of the light that enters your home.
Reduces Sound Penetration
In addition, High-Performance Low-E4 glass also reduces sound penetration significantly, even when compared to single-pane glass.
Standard Feature
Low-E4 glass is exclusive to select Andersen® windows and doors, and is included as a standard feature on all Renewal by Andersen® window products.
