An Alternative to Vestibules

Not all buildings have room for vestibules. Not all owners want a vestibule, and there are spaces where a vestibule is just not practical or takes away from the design intent.

As part of our response to the Design and Construction Community asking for information and data to support using an air curtain in place of or along with a vestibule, we did two things:

  1. We researched air curtain (a.k.a. “air door”) effectiveness via both CFD modeling and physical testing,
  2. We went to AMCA (Air Movement & Control Association) and asked AMCA to do its own research on air curtain effectiveness on behalf of all the air curtain manufacturers.

Here is the Berner infographic summarizing the results. Please click on it to view the full size PDF version.
