KalsiFlex and KalsiWAB fibre cement boards are appropriate for ceiling application in both dry and wet areas. They are a lightweight yet durable board that offers exceptional dimensional stability and years of functional service. Kalsi fibre cement board systems for ceilings range in thicknesses from 4.5mm to 9mm and can be nailed/screwed to timber framing or metal framing. The joints between the boards can be left visible or finished using applying PVC joiners, or compatible multi-purpose gypsum based compound and tape for joint treatment. Kalsi panels can be a good alternative to ceiling tiles. The extra smooth surface is ready to receive a wide range of finishes.
