What makes Renewal by Andersen windows and doors unique?

Renewal by Andersen windows are unique because they encompass the functional and visually appealing features that are so important to you:

Energy Efficiency

Our energy efficient windows can save you money on heat and air. This is especially important when you live in a city like Pittsburgh, where your home endures cold winters. Because window frames are custom fit to your home, they have weathertight seals that block outdoor air. It’s easy to keep your rooms a comfortable temperature with RbA replacement windows!

Our patented replacement window material, called Fibrex, combines the best qualities of vinyl and wood in a durable and low maintenance polymer. Although Fibrex encompasses the expensive look and visual appeal of wood, it doesn’t require any chemical treatments of paint. Color is pre-blended into the material during the manufacturing process, leaving you with a chemical free fixture in your home.


Renewal by Andersen also provides a large variety of styles, finishes, hardware, and more. You are sure to find a look that will compliment and enhance in the interior or exterior of your home. Find something that will blend in with your home’s current decor or choose a style of window that will stand out as a strong piece.  Whatever you decide, our specialists are here to guide you every step of the way.



Precision can make a big difference in replacement patio doors and windows. Before manufacturing your particular piece, Renewal by Andersen measures the opening in your wall to the 1/16th of an inch. Working with such precise measurements means that we can install your windows or doors with minimal adjustments onsite. This is the best way for us to achieve the perfect frame and glass combination for your opening, making your new fixture a beautiful compliment to your home’s architecture.
