Understanding Energy Efficient Doors

Lighting, electronics, windows, roofing, and doors all play a major factor in your building’s energy efficiency.  When selecting features for an entrance, architects and designers are often forced to choose functionality and efficiency over style.  With Dawson’s new Thermally Broken custom entrances, you can have both!

Energy Efficiency

What are the most energy-efficient doors?

With so many factors at play, the “most energy-efficient” doors are ultimately doors with low U-Factors. This is a measure of how much heat is lost through the door.  Other factors such as the Solar Heat Gain Coefficient  (SHGC) and air leakage are also accounted for when considering heat loss in a building.


What classifies a door as an energy-efficient door?

Doors that combat unwanted heat transfer with excellent insulation and have a thermal break make for the most energy-efficient doors.  They are the barrier between inside and outside temperatures.   U-factor measures the rate of heat transfer through a product. Typical values of doors and windows range from 0.4 – 1.0. The lower the U-factor, the better the door keeps in heat.
