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.

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.

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.

 

Andersen Tip

 

National Fenestration Rating Council	The best way to compare the energy efficiency of windows and patio doors is to look at their NFRC labels. Any window worth buying will have one displayed.
	Products with the ENERGY STAR label are designed to use less energy, help you save money on utility bills and help protect the environment.

We stand by our products, and the people who use them. Our limited warranty is known throughout the industry as one of the most comprehensive and reliable backing policies available. The limited warranty never loses value over its lifetime because it is non-prorated. Being fully transferable, it can also add real value should you decide to sell your home. Visit the Andersen Warranties section for more information.

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. Visit our Parts Catalog for a detailed list of what’s available.

 

Window and Door Testing
 

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.
