To maintain the pressure level needed, the facility replaced the existing ceiling panels with new CALLA Health Zone AirAssure ceiling panels from Armstrong Ceiling & Wall Solutions. When placed in a standard ceiling suspension system, AirAssure acoustical ceiling panels form a tight seal and reduce airflow leakage through the ceiling plane up to four times more than panels without AirAssure performance. By swapping the ceiling panels, room pressured increased.
The replacement of the ceiling only took a day, so extended downtime for the room was eliminated. Also eliminated were labor costs involved in caulking ceiling panel edges, an action some facilities are forced to undertake to achieve desired pressure.
