ROXUL Inc. has launched the RSPEC online tool to offer architects and specifiers easy access to the information they need to specify insulation in commercial projects.
The requirement for buildings to be designed with a continuous air barrier has been making its way into U.S. building codes ever since the state of Massachusetts first did in 2001 with the introduction of Section 1304.3.1 Air Barriers.
Air leakage is the unplanned, unpredictable and unintentional airflow across the building enclosure. This makes air flow control important for several reasons: to avoid air transported moisture and moisture damage, to reduce energy losses and to ensure occupant comfort and health.
