Whether you’re living in your forever home or thinking of selling your property in the future, an energy-efficient patio door is a good investment. It can help maintain a comfortable temperature inside your home so your heating and cooling system don’t need to work as hard. The less dependent you are on your HVAC system, the more energy you’ll save.
Learn what makes a patio door energy-efficient from a trusted door and window company.
ENERGY STAR® doors must be manufactured by an official partner as well as tested and certified by the National Fenestration Rating Council (NFRC). The ENERGY STAR criteria for doors depend on the glazing level and ratings from the NFRC, which include:
U-Factor – Used to measure heat transfer, the U-factor ranges between 0.25 to 1.25. Doors and windows with a lower U-factor can offer better insulation.
Solar Heat Gain Coefficient (SHGC) – SHGC measures how well a door can stop solar heat gain. The lower a patio door’s SHGC, the less solar heat it allows inside your home.
Glazing Level – Glazing level pertains to the amount of glass your door has. Opaque doors don’t have glass while units greater than or equal to half-lite are made of half-glass.
Characteristics of ENERGY STAR Doors
ENERGY STAR doors usually have multiple panes. The space between the glass is filled with special gases that improve the door’s insulation. The patio door’s frame material can also contribute to its energy efficiency. At Renewal by Andersen, our patio doors feature our unique Fibrex® material and low-E glass panels for superior energy efficiency and weather protection.
