High rise duct
Webshafts, refuge spaces and other egress routes. The high-pressure side of the barrier is either the refuge area or an exit route. The low-pressure side is exposed to smoke. Airflow from the high-pressure side to the low-pressure side (through construction cracks and gaps around doors) prevents smoke infiltration. A path that channels Webrisers are excessive noise and duct leakage created by high fan pressures, or the potential for under ventilating portions of the building. Either scenario can result in an unsuitable …
