Renewal by Andersen has put together this list of frequently asked questions about replacement windows in order to keep homeowners better informed. If you have any further questions, please don’t hesitate to called Renewal by Andersen of St. Louis for replacement window facts and information.

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 overall 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 of the window.

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, but by replacing your windows, you can expect to save up to 40% on your energy costs.

"I'm getting ready to do my 2nd round of window installation with Anderson Windows. I really appreciate the great financing options that they offer! They have top notch sales and installation experts who are very kind and considerate of their customers' wishes. The windows I have installed look great and I am so excited to get the next group of windows put in. My house looks so much brighter with my new windows. I definitely recommend Renewal by Andersen of St. Louis."

"We recently contracted with Renewal by Andersen to replace 5 windows in our home. First of all, we were very delighted that the time from contract to installation was less than two months. Joel and Craig arrived precisely at the agreed-upon time and spent less than four hours from start to completion of installation, including time to demonstrate opening/closing the windows and any questions we had. We were very pleased with the knowledge and professionalism of Joel and Craig, and, of course, we’re very pleased with the windows and how nice they look. We definitely recommend Renewal by Andersen."

"I replaced my front door and several windows. The install team did a great job with installation and clean up. Even covered floors and stairs. The team was very courteous and did a very professional job. Now our windows look great and we love our new door. I would recommend Renewal by Anderson in a heartbeat."
