e., a membrane layer roofing system) it acts as an air retarder. Separate air obstacles are sometimes included right into our website roofing systems. When air barriers are integrated right into wall systems, they are typically consisted of to regulate air movement, control moisture and/or decrease energy consumption, or to stop pumping as a result of wind, which can create uplift with mechanically attached membranes.

To decrease the potential of interior air being pumped into the roof system an air obstacle must be found at the roof deck level under the roofing insulation, securing all roof covering deck voids. The deck itself can be a barrier if it is monolithic, such as cast-in-place concrete.
