UV Protection

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.

Solid Wood Construction

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.

Low Maintenance

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.

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.

Energy Efficient Windows & Doors

Andersen has the glass you need to get the performance you want, including a variety of Low-E glass options to help you control heating and cooling costs in any climate, plus SmartSun glass that meets ENERGY STAR® qualifications in all climate zones.

Andersen patio doors and casement windows feature unique locking systems that pull the window or door panel snugly tight. The result is an enhanced weather seal, plus improved security.

Our weather-resistant construction seals out drafts, winds and water so well, you can relax in comfort whatever the weather. We carefully select weatherstripping to match each style of window and door to make sure you enjoy superior comfort and reliability.

Transferable Limited Warranty

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.
