We are about to manufacture a mineral based building board in South Africa. These boards can be used for ceilings, walls, wall pannels, fireproofing, cladding, partitioning, floors etc etc. They are 'green' and eco-friendly, better than gypsum, cement board, marine ply, shutter ply etc etc and CHEAPER!We also produce expanded vermiculite (gold colour). It is of top quality and we have 5 grades on offer from super fine to large.
