A number of factors contribute to a window or door's performance — from UV protection and solid wood construction to low maintenance longevity. Learn more about Andersen's unique combination of essential elements.
UV Protection - Andersen Advantage
Ordinary dual-pane glass lets 62% of UV light pass through. Our High-Performance™ Low-E glass cuts that down to 17% with virtually no effect on the clarity and color of the light. With Low-E glass, if your thermostat is set at 70°, the temperature of the innermost glass pane won't drop below 57° even if it's 0° outside. In warm climates, Low-E glass works just as hard to keep your home cool. For extreme climates, we also offer High-Performance Sun™ glass for maximum UV protection and temperature control.
Low Maintenance - Andersen Advantage
All Andersen® windows and doors feature the Perma-Shield® system, which protects the window’s exterior beautifully for decades.* It also eliminates the need to paint—and repaint. The material used to make a frame determines a window’s thickness, weight, and durability, and it also has a major impact on its thermal characteristics. The frame is also used in determining a window’s U-Factor. Since the sash and frame represent from 10 to 30 percent of the total area of the window unit, the frame material will definitely influence the window performance. Wood-Clad We believe windows and patio doors should be made of wood, but exterior facings should be protected from the elements. That’s why we manufacture wood-clad windows and patio doors with vinyl exteriors. They offer beauty, luxury and natural appeal while maintaining high standards of weather resistance with an extra surface that lowers their maintenance requirements. The interior wood allows you to retain an attractive paint or stain finish indoors. Our basement windows feature Fibrex® material, a wood/polymer composite for best results at ground-level.
Solid Wood Construction - Andersen Advantage
Our wood interiors feature superb styling — with no visible finger joint seams. Natural wood provides structural stability and is one of the most effective insulators available. For added reliability we treat the frame and sash parts with wood preservative. Andersen interiors bring warmth into your home as well as style with rich natural wood that you can stain or paint to enhance the decor of any room. Fine craftsmanship, elegant styling and precise detailing make the view of your windows as impressive as the view from them.
Energy Efficient Windows & Doors - Andersen Advantage
We publish standard energy-efficiency performance ratings on all our products— ratings that are consistently among the best in the industry. Homes with Andersen® windows and doors can dramatically reduce their heating and cooling costs.
Transferable Limited Warranty - Andersen Advantage
Andersen window & doors are covered by our exclusive Owner-to-Owner®limited warranty. Most other window warranties end when a home is sold, but our coverage- 20 years on glass, ten on non-glass parts- is completely transferable from each owner to the next. And, because it is not prorated, the coverage offers full benefits, year after year, owner after owner, so it can add real value when you decide to sell your home. Plus, we have one of the largest service networks in the industry, so help is always there if you need it. Visit our Warranties section for more information.
Longevity - Andersen Advantage
We expect our products to live well past their warranty period. But kids still throw baseballs and even the most durable materials can wear out eventually. That’s why we can provide replacement parts for our windows and doors, even ones that were discontinued 50 years ago. To make sure that our windows and doors last* we put them through testing in the lab and the field that few other windows endure. Some are exposed to wind speeds up to 155 MPH. Others face sudden temperature changes from -20°F to 180°F.
