Conwed Access Torsion Spring Ceiling System has a uniform look with easy to use downward-hinged access panels. This completely hides the suspension system, maintains proper panel alignment, and allows your design to be completely custom. This system shines in large public spaces where access to mechanical equipment, network trays, and electrical is needed on a regular basis. The core construction is dimensionally-stable 6-7 PCF fiberglass board with a ⅛” 16-20 PCF molded glass facer. All system components are rust-free aluminum and galvanized steel to minimize maintenance.
