Berner Air Curtains: A Viable Alternative to Vestibules

Berner Air Curtains: 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 the link below to view the full size PDF version.

What is an Air Curtain / Air Door?

Berner Air Curtains / Air Doors

An air door, also called an air curtain, employs a controlled stream of air aimed across an opening to create an air seal. This seal separates different environments, while allowing a smooth, unhindered flow of traffic and unobstructed vision through the opening. Because air doors/air curtains help to contain heated or air conditioned air, they provide sizeable energy savings and personal comfort when applied in industrial or commercial settings. Air curtains can also be used to stop the infiltration of flying insects.
