What Makes a Patio Door Energy-Efficient?

Patio doors would make a great addition to any home. They have a classic aesthetic appeal and provide plenty of natural light, brightening the mood inside your home. If you’re considering installing patio doors, make sure they’re energy-efficient. Remember that doors account for 11% of heat loss in an average home. It may not seem like much at first, but small costs can quickly add up. 

What makes a patio door energy-efficient? 

Door Frame and Glass Panes 

Glass is a poor insulator while some door frame materials have poor insulative capabilities. When choosing new patio doors, make sure to pick one with an insulative door frame and energy-efficient glass. The same goes for choosing windows. 

If you’re looking for energy-efficient doors and windows, you may want to consider doors and windows made from Fibrex®, an exclusive composite made from reclaimed wood fibers and thermoplastic polymers. Fibrex has excellent durability and insulative capabilities, making it an ideal material for doors and windows. Renewal by Andersen also offers a wide variety of energy-efficient glass options. High-Performance™ Low-E4® glass, our standard glass package, is 45% more energy-efficient in winter and 56% more efficient in summer.

Total Window Performance 

Keep in mind that one or two energy-efficient features won’t make a door energy-efficient. When choosing a replacement door, you need to examine its total performance. ENERGY STAR®, a government-run program, certifies doors and windows that have passed its stringent standards. 

How do you pick one from dozens of doors certified by ENERGY STAR? By checking the National Fenestration Rating Council’s (NFRC) ratings under the ENERGY STAR label. Here’s an overview: 

  • U-factor – The rating indicates a door’s insulative capabilities. The lower a door’s U-factor, the better it can prevent heat transfer. 
  • Solar heat gain coefficient (SHGC) – The rating gives you an idea of the amount of heat from the sun that can pass through a door. The lower the SHGC rating, the less heat that can pass through your door. 
  • Glazing level – An opaque door contains no glass. A door less than or equal to half-lite is made of 50% glass or less while a door greater than half-lite is mostly made of glass.
