Why Your Patio Doors Are So Energy-Efficient

Renewal by Andersen® patio doors the best options for an energy-efficient home because of their amazing construction and glass packages. But what makes them so efficient?

Energy-Efficient Glass

All our doors feature High-Performance™ Low-E4® glass designed to protect a home from high heat gain. They are coated to levels that allow a good amount of sunlight in, without too much heat penetrating your home. We also use an argon gas blend to fill the space between panes, resulting in better insulation. Every glass package we provide is covered by a 20-year limited warranty.

Durable Frames

Our windows and doors are built with Fibrex® frames. Fibrex is the product of decades of research and development in an effort to produce a framing material that will be as strong as wood, but as easy to maintain as vinyl. Our frames are covered by the same 20-year warranty coverage on the glass we use.

Professional Installation

What makes outstanding window and door performance possible, in combination with high quality framing materials and glass options, is professional installation. Our brand is known for a full custom installation process, created to cater to every customer’s needs – from design to post-installation clean-up. Our confidence in our installation procedure is reflected by its inclusion in the warranties we provide as well.

"I just bought my first house. My patio sliding door was rotten. So, I needed it to replace it. Renewal by Anderson of Southern Missouri listened to what I wanted and delivered it. They did a fantastic job of installing and cleaning up afterwards. They did it even in freezing rain that day I was scheduled to have it replaced. They even had a follow-up to check things out and do the touch ups. I'm amazed at there work. Great job Renewal by Anderson."

"On Feb 1,2024 my husband and I selected Renewel by Andersen for windows for our entire house. It made our house more beautiful with the picture windows. Made the outside more attractive, and on the inside. We did 14 windows. We had 4 men come to do the job in 1 day And they were very friendly, efficient,fast and cleaned up inside and outside perfectly. And most importantly we noticed the heating furnace runs less,therefore saving us money on our gas bill. We live in SW Missouri. We recommend anyone who wants to replace windows in their home to pick Renewal by Andersen. Sincerely, Darius and Nancy Durman"
