The Anatomy of Truly Energy-Efficient Entry and Patio Doors

The Anatomy of Truly Energy-Efficient Entry and Patio Doors

November 28, 2019

If you’re in the market for new picture windows or looking to upgrade your entry or patio doors, chances are you’ve come across energy-efficient options. But what does energy efficiency mean when talking about doors?

Today’s article from Renewal by Andersen® of Milwaukee sheds light on the features and elements that make entry and patio doors energy-efficient.

A Primer on Energy Efficiency

Energy-efficient doors provide better insulation than their standard counterparts. This means that they are more efficient when it comes to keeping warm or cold air inside or outside the home, depending on what the weather is like. While there are countless energy-efficient options to choose from, homeowners need to be wary of products that are only energy-efficient by name.

Below are the characteristics of truly energy-efficient patio and entry doors.

Manufacturing Requirements

The best way to ensure that your doors are energy-efficient is to check whether they have been rated by ENERGY STAR®. Even better if the doors are manufactured by an official ENERGY STAR® partner such as Renewal by Andersen, a company also known for their energy-efficient replacement windows.


Materials such as fiberglass, wood cladding and steel with a polyurethane foam core are newer on the market and are more energy-efficient than other materials. These are ideal for entry doors because these materials ensure a tighter fit, making them extremely efficient in terms of insulation. As for patio doors, they should be made of fiberglass, wooden frame, or vinyl combined with multiple gas-filled low-E glass panes for optimal energy-efficiency. Energy-efficient patio doors share a lot of qualities with energy-efficient windows.

Hear From Our Customers

I cant express how happy we are with choosing Andersen for our window installation. Our sales representative was knowledgeable with product and answered any questions we had without hesitation. I did also fill out a survey that was sent in an email, but sadly I failed to personally name the two gentlemen that performed the actual installation. Barrett and Francisco were our guys, and let me tell you, they were outstanding!!! They did Excellent work and were professional as well as efficient and made this a smooth, none evasive process for us. I strongly recommend this company and these installers to anyone in need of windows!!! My husband and I could not be more pleased we chose Andersen for replacing our windows!!!

This was a great crew to work with. Both the original install manager we worked with (Jay) and the install team (Daniel, Mason, Tony, Ethan, and Jose). Everyone was very professional and knowledgable. They answered all my questions and the end result on the house is great. In 3 days they replaced an old bay window with a new bay window, a set of french doors on the patio with a sliding patio door, and our old front door with a new front door and storm door.

Jason and Brett did an awesome job installing our doors. We had separate installers a month earlier for our windows who also did a fantastic job. They were all very professional and cleaned up almost better than the area looked before the installation! Since these were both jobs that took more than one day the installers were great at keeping us informed on the status of where the project was at along the way.
