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.

"Excellent service and product! They checked in with me every few weeks while we were waiting for the order. I was impressed with Sam, who measured my windows and headed the installation crew. He was respectful and patient with his team. They cleaned up after themselves. Before the new windows I had huge windows that didn’t open. Now I feel much safer and get better temperatures in those rooms."

"My experience with Anderson Renewal was amazing! From the first meeting with Miranda to choose my windows and doors to the installation provided by Tim and his crew was a pleasure! I just bought a home built in the 1960's that needed new windows and a new double front door with sidelights. As everyone knows Anderson Windows are great, but it was the people I interacted with from Anderson that made it such a great experience. It took three days for the windows and door to be installed and they "worked" every minute they were here. My huge front door took most of the day to install because they had to put in a new header and other improvements to make it fit! They even put up new drywall on the inside. Many people in the neighborhood have stopped by to comment on my beautiful front door! I think the crew left my house cleaner than it was before they started! Constantly cleaning up after themselves. I am thrilled with my windows and feel lucky to have met the team at Anderson."

"Very professional staff . No pressure sales. The job they do is neat and clean, no cleanup left for the owner. Communication is great. Always informed on the status of of your product, AND the tin of cookies you receive afterwards is a pleasant plus."
