Windows FAQ

Answering Your Questions About San Francisco Area Replacement Windows & Doors

Renewal by Andersen® has compiled a list of FAQs in order to help homeowners better understand all that their windows do for their homes and for their lives. We hope that these questions will provide you with some of the information you need to make a decision on your window replacement needs.

What is a replacement window?
A true replacement window is a window that’s custom built to fit within the opening of an existing window. It’s built to fit precisely and can be installed without disturbing the interior and exterior areas around the window.

Why should I replace my home’s windows?
Window replacement affords a variety of benefits including higher resale value for your home, reduced energy bills, and increased comfort of your home.

What is Low-Emissivity or Low-E Glass?
Low-E Glass is outfitted with a microscopically thin, virtually invisible, metal or metallic oxide layer deposited directly on the surface of one or more of the panes of glass. The Low-E coating reduces the infrared radiation from a warm pane of glass to a cooler pane, thereby lowering the U-factor and making for more energy efficient windows.

What is Fibrex?
Fibrex is a sustainable composite material that combines the strength and durability of wood with the easy maintenance of vinyl. For further information, visit our Advantages of Fibrex page.

How much money can I expect to save on my heating and cooling bills?
The amount of money you will save on your heating and cooling bills is relative to the type of window you currently have installed. For more information on saving money on your energy bills, please visit our Energy Efficient Design page.

What type of warranty comes with the windows?
All of our replacement windows come with a manufacturer’s limited lifetime warranty. This warranty is transferable should you sell your home. For more information, visit our RBA Warranties page.

What types of Payment methods & Financing do you offer?
We offer a variety of payment methods and financing options depending on promotional period. For more information, visit our Financing Options page.
