Ensuring proper air barrier adhesion for maximum performance

Using a fully adhered air barrier, whether sheet-applied or fluid-applied, is essential in creating a continuous barrier which will minimize air leakage. How well the membrane is bonded to the wall substrate will greatly affect the barrier’s performance. This adhesion is a critically important, yet often overlooked, factor in air barrier selection, and it impacts the building envelope’s performance from the day it is installed and throughout the life of the building.

Role of air barriers in mitigating disease transmission

The importance of infection control and the impact of operating conditions on the built environment have taken renewed focus in the wake of the COVID-19 pandemic. As a part of the ongoing response, industry organizations, such as the American Society of Heating and Refrigerating and Air-conditioning Engineers (ASHRAE), have released updated considerations for design and construction professionals, including airflow strategies and temperature and humidity controls, as well as ventilation and pressurization.
