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.

"Quality product, quality workmanship. Everyone I interacted with at Renewal by Andersen of SW Missouri had pride in their work from sales to financing to project oversight to installation. It must be a great company to work for because that shows in the professionalism of the staff. Best of all, they want happy customers and go out of their way to make sure that happens. Yes, I love my windows (but I knew I would--it's a great product). Friendly, helpful, easy financing, and yes--they pass costs on to the customer for this, but it meant that I was able to get the windows I wanted and needed for my creaky, lopsided old house. Couldn't be more pleased."

"The company representative who met with me initially was very direct, told me how the process would go, explained about why Anderson windows are of such good quality and how they stand by their products and their workmanship. My 3 windows arrived when they said they would, & the men who installed them were very professional, polite, & efficient. They showed me how the windows work and left the room as tidy as it was before they did the installation."

"We just had our windows done by Renewal. They kept us informed about the progress of manafucture & installed at the approximate date. Good qualtity & if you didn't know that there were screens on the windows you would think they were missing. Very clear view. Great in this hot weather, the house stays cool."
