These open-grid panels are engineered for flexibility, making them a favourite among architects and designers working across commercial, retail, education, and transport sectors.
The Key Open Cell system creates a striking geometric ceiling aesthetic while improving ceiling airflow, accessibility, and acoustic performance. Available in a variety of materials including powder-coated aluminium and timber-look finishes, these panels can be specified in square or rectangular cells with custom grid sizes to suit any project vision.
