What Makes a Patio Door Energy-Efficient?

As with replacement windows, the energy efficiency of patio doors is impacted by all the different components of the unit, from the quality of the glass to the frame material. If you’re planning to install new patio doors soon, it’s important to have a basic understanding of the factors that can make or break a unit’s energy efficiency. Read on for a guide to patio door energy efficiency from Renewal by Andersen® of Portland.

What’s an energy-efficient patio door? 

An energy-efficient patio door is one that contributes to your home’s overall insulation in a positive manner. With an energy-efficient patio door, your HVAC system won’t have to work as hard to maintain a comfortable indoor temperature, which results in energy savings for you.

How to Identify an Energy-Efficient Patio Door

The easiest way to identify an energy-efficient patio door is to look for the ENERGY STAR® seal. ENERGY STAR has standards in place to assess replacement windows and door products, and only those that have met or exceeded these standards bear the label.

To be sure that your patio door is energy-efficient based on your local climate’s requirements, you also need to take a look at door labels provided by the National Fenestration Rating Council (NFRC). Typically, NFRC labels will feature ratings like U-factor and solar heat gain coefficient, both of which have ideal scores depending on your location.
