BEC-GD with Metro Detroit CSI: Roof Air Barrier-Vapor Retarder: What, When & Where Panel Discussion

The 1 Health, Safety, Welfare (HSW) AIA Continuing Education unit will be made available by Metro Detroit CSI

In-person Attendee: $5.00 at the venue
Virtual Attendee: $5.00 on Eventbrite

Architects are sometimes confused by the difference between a Roof Air Barrier and a Vapor Retarder, as the terms are often used interchangeably. Roof Manufacturers will often recommend an Air Barrier or Vapor Retarder as part of a roof assembly, and so Architects include it in the Specification.

On the other hand, Contractors will often offer the deletion of the Air Barrier/Vapor Retarder as part of Value Engineering, and if Architects do not fully understand the reasons the Manufacturer may recommend an Air Barrier/Vapor Retarder, they may have difficulty (1) confidently explaining the difference between an Air Barrier and Vapor Retarder, and (2) defending the retention of the Air Barrier/Vapor Retarder as an essential part of the Roof Assembly.

The virtual and in-person (hybrid) Panel Discussion by four national and international Manufacturers, a national Roofing Contractor and a nationally respected Building Scientist specializing in Roofs will help the Architects attending the Program to come away with a better understanding of Air Barriers and Vapor Retarders, when and where to use them, when they may be able to be “VE’d” out, and when they must be retained as an essential part of supporting the Health, Safety, and Welfare of their Clients and the ultimately the Community at large.


Participants will learn the difference between a Roof Air Barrier and a Roof Vapor Retarder;
Participants will learn when to use a Roof Air Barrier vs a Roof Vapor Retarder;
Participants will learn where to use a Roof Air Barrier or Roof Vapor Retarder;
Participants will learn when or where a Roof Air Barrier or Roof Vapor Retarder may not be required.
