Calcium Silicate Board Partition is high density very strong low price long lifer durable option in comparison with gypsum board ceiling. Its performance is 15 times higher than gypsum boards. It provides higher fire resistance, acoustic and thermal insulation than gypsum boards.


Wedge HDCASI 1350 Calcium Silicate Ceiling Boards are non-asbestos, non-combustible, high density calcium silicate building boards. These boards are manufactured from a homogeneous mixture of non-asbestos fibre silicates and cement to achieve high impact resistance and very high compressive strength with minimum thickness of 4 mm to maximum up to 20 mm. These calcium silicate boards are green building product label. It does not contain any harmful substances or inorganic fibres and are free from formaldehyde and toxic emissions. The architectural appeal of the board surface is ready for most forms of decoration.
