According to the Department of Energy (energy.gov,) replacing older doors in your home might lower heating and cooling costs. Here are some tips on how to choose the perfect exterior door.
When selecting doors for energy efficiency, it’s important to consider their energy performance ratings about the local climate and your home’s design. This will help narrow your selection. Look for the ENERGY STAR label to help identify energy-efficient products for your climate.
- The National Fenestration Rating Council (NFRC) label helps you compare energy performance ratings of doors. The label shows the door’s solar heat gain coefficient (SHGC) and U-factor. Learn more about the NFRC label.
- Look for a low SHGC in a climate that mainly requires cooling and a high SHGC in a climate that requires heating. The range is from 0 to 1. SHGC measures how well a product keeps out solar heat.
- Look for a low U-factor. The lower the U-factor, the better the door keeps in heat.
