FAQS ABOUT WINDOWS FROM ST. LOUIS HOMEOWNERS

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.

"Renewal was fantastic! They kept you in the loop from ordering to installation. They informed you at every step of the process of what was happening. The installers were kind, courteous, and professional. Everything was cleaned up after the installation. It was as if they hadn't been there except to see your beautiful new windows. I highly recommend them."

"3rd time using RBA for window replacement. Again, a very positive experience, the windows are great, the installation was done right, the professionalism was apparent from start to finish. Still have existing windows to be replaced and will definitely use RBA again to do it in the future."

"Renewal by Andersen was a good experience for us in replacement of our windows. From the initial meeting with the sales representative, Leslie, through the waiting period for manufacturing, and then to the installment process, our experience was excellent! Communication is key for me and we were kept informed and updated as our windows were being ordered and manufactured. Calls to update us on the installation process were welcomed and appreciated. They know how much is too much so they don't pester you with unnecessary contact. We love our new windows!!! Did I say that already??😂 We can tell a major difference in reduced Street noise and also the temperature at our windows. Excellent company, highly recommend!!"
