Air Curtains Approved for Vestibules   Publish Date: 12/1/2014

Air Curtains Approved as Exception to Vestibule Rule
Last year, the International Code Council (ICC) heard testimony and voted on changes to the 2012 edition of the International Energy Conservation Code (IECC). One result of this hearing was the following code change which will be reflected in the 2015 code:

Exceptions: Vestibules are not required for the following:

6. Doors that have an AIR CURTAIN with a minimum velocity of 2 m/s at the floor, have been tested in accordance with ANSI/ AMCA 220 and installed in accordance with manufacturer’s instructions. Manual or automatic controls shall be provided that will operate the air curtain with the opening and closing of the door. Air curtains and their controls shall comply with Section C408.2.3.
