High Performance & High Strength Render Carrier Board.
The STS Construction Board is a heavy-duty fibre cement board highly recommended by many leading render manufacturers.
It’s high strength and density create an impact resistant, dimensionally stable and weatherproof construction board which lends itself for use as an external render carrier.
The simple fibre cement composition provides a perfect surface on which to receive thin coat render systems such as the brands stated below.
By using the STS Construction Board you have the assurance of a solid foundation meaning not only a stunning render finish, but also the peace of mind that it will last for years and remain crack free.
What is fibre cement board made of?
Portland Cement: binds the ingredients and is made with limestone, clay and iron. Cellulose Fibres: treated, organic fibres which act as a filler. Sand: highly durable and creates all weather performance. Water: dissolves the wood pulp; activates and hardens the cement. STS Construction Boards have no need of fibreglass mesh for strengthening, which of course is almost impossible to recycle and very irritable when cutting.
