High impact strength fiber cement boards from Thailand 
A lot of people are asking us what fiber cement boards are suitable for lightweight concrete infill technology. We have tried a lot of different fiber cement boards and have found good option in terms of quality and price. SCG smart board is fiber cement board that most suitable choice for external and internal wall and partition.  It has strength, durability and elasticity in one time. The board, composition of Portland Cement, Silica and Special cellulose fiber through autoclave process is specifically designed for wall application.
