• Ideal for interior and exterior ceiling solutions.

Kalsi is a long-lasting and stable ceiling board.

KalsiCeiling  is a fibre cement board designed especially for ceiling application in both dry and wet areas. It is a lightweight yet durable board that offers exceptional dimensional stability and years of functional service.

KalsiCeiling  in thicknesses of 3mm, 4.5mm and 6mm can be nailed/screwed to timber framing or metal framing. The joints between the boards can be left visible or flushed by applying Kalsi Joint Compound® or other compatible multi-purpose gypsum based compound for joint treatment. For enhanced performance, it is recommended to use Kalsi Joint Compound with its special anti-crack formulation that is proven to be compatible with Kalsi fibre cement boards in interior ceiling applications.

KalsiCeiling  also can be a good alternative to ceiling tiles. The extra smooth surface is ready to receive a wide range of finishes.
