Double Door Airlock

The double doors at the front of the building create an airlock that prevent substantial amounts of heat or cool air from escaping the building when entering and exiting. This building strategy prevents energy-consuming drafts and makes the building more energy-efficient.

Exterior Doors

Interior Doors

*Green Tip:  If you don’t need it, don’t use it! The automatic door uses electricity and overrides the energy-saving airlock feature!
