A Sticky Subject – Adhesion of Air and Water Resistive Barrier Materials

Presented by Laverne Dalgleish

Air and water resistive barriers need to withstand the loads imposed on them by wind effect, stack effect and mechanical pressurization/depressurization. If the material is held in place by adhesion, the adhesion value must be greater than the combination of those three forces. What about the long-term durability of the adhesive? Should you consider the material properly installed if the pull adhesion value at the time of installation is greater than the combined forces?

The presentation will review independent research on 15 years of field tests of various air barrier materials on various substrates on real life construction sites. This will show how it differs from laboratory testing and what one can expect to be base standards for adhesion to either provide guidance in specifications, or as a quality control tool for site observation.

Learning Objectives:

1. Identify the performance requirements identified in ASHRAE 90.1-2016 in regards to air barriers and the requirements to withstand positive and negative loads due to stack, wind and mechanical pressures.
2. Become acquainted with requirements of air leakage verification as identified in ASHRAE 90.1-2016 and the periodic field inspections required on the air barrier during the construction process.
3. Interpret what adhesive values means in regards to on-site quality control of various air barrier materials.
4. Compare the values of adhesion between various air barrier materials to help with design decisions to ensure the airtightness layer does not become compromised.

EXECUTIVE DIRECTOR – 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.
