Key Points


  • A product many be called a building air barrier if it meets certain performance thresholds.
  • AS/NZS ISO 14857:2023 is a recently-adopted test standard for measuring the air permeance of a sample of product
  • There are many products available in Australia that may meet the threshold for air permeance to be considered air barriers


Introduction


High efficiency construction requires use of control layers such as air barriers. Though many building membranes are marketed as air barriers, they are not the only product class to serve this purpose. Self-adhered membranes, mechanically-fixed membranes, rigid products, spray foam products, fluid-applied membranes, and many other product classes may meet thresholds to be considered adequate air barriers for buildings. Recently-adopted, AS/NZS ISO 14857:2023 is a test standard for measuring the permeance of a 1 square-meter sample of product on a scale representative of its real-world application. This presentation will review requirements for product classification as an air barrier, compare the test method to others used in Australia and throughout the world, and review many air barrier products available in Australia.

Speakers

  • Laverne Dalgleish (Executive Director of Air Barrier Association of America)

    Laverne Dalgleish

    Executive Director of Air Barrier Association of America

    Mr. Laverne Dalgleish is the Executive Director of the Air Barrier Association of America (ABAA). As such, he works to champion energy conservation in buildings while educating the building owners and designers about the benefits of energy conservation such as durability, comfort, reduced maintenance, reduced HVAC equipment costs and the positive impact on the environment.

    Mr. Dalgleish travels North America on a weekly basis to educate building owners and designers on the benefits of effective and working air barrier systems in buildings. This education mission includes working with standards development organizations, training and education groups, government policy departments, and quality assurance program developers for the construction industry. Mr. Dalgleish is the Secretariat of two ISO Committees, ISO TC61 SC10 Cellular Plastics and ISO TC163 SC3 Thermal Insulation Products. He is also Chair of the ULC Thermal Performance in the Building Environment Standards Committee.

    Mr. Dalgleish was the key developer of the ABAA Quality Assurance Program for the installation of air barrier systems in buildings. This program is based on ISO9000 and ISO 12576-2 but brings the ISO requirements together with practical applications for the air barrier industry.

    Sean Maxwell

    ATTMA Scheme Manager Australia and New Zealand at Air Tightness Testing & Measurement Association (ATTMA)

    I am a key booster of Australia's growing industry of building science professionals. Grounded by experience in research, I have a keen desire to get to the root causes of building systems defects. I also wish to advance the state of building science in Australia and abroad.
