Hi !

According to building envelope compliance documentation Part I, revolvning doors should have air leakage less than 1,0 cfm/ft2.
A manufacturer of revolving doors informed me that all revolving doors on the market have a air leakage much higher than 1,0 cfm/ft2 and that this figure is probably set with a swinging door in mind.
Has anyone found a revolving door with a air leakage below 1,0 ?
