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.

"Their workers who installed the windows were excellent. Our experience with the sales rep was pleasant. He did not pressure us. He made suggestions that saved us money."

"I would give everyone involved in the whole process a 10 out of 10. With the exception of the window installation crew. They get an 11 out of 10. I can't express in words what an excellent job they did. They went above and beyond."

"Although it is a process and doesn't happen overnight the wait is worth the end results. A Representative will come to your home and walk you through the entire process. It does take a few weeks from the time they send someone to your home to personally measure your windows to the time the factory specifically custom cuts your windows and ships them out. However, the end result is overwhelmingly satisfactory. The crew sent to install them were professional, cleaned up after the job was completed and did the job in half the time they thought it would take. Highly recommend!"
