Energy Star Compliant Doors
Any manufacturer want his suplies to have an Energy Star label. It means
they are above a certain insulating value and air infiltration rating.
I would not but any window or door that is not since I live in a high
heat-cooling area. Check each units independant rating for air
infiltration and R or U value. If one unit doesn`t say it is "Energy
Star" likely it fails their requirements.
