    Renderflex

    High performance dimensionally stable render carrier board

    RCM Renderflex is a high-performance cellulose fibre cement building board, offering excellent strength, weathering and stability properties when used in conjunction with polymer renders.

    Renderflex has been specially formulated to achieve a strong key between polymer basecoats and top coats. The unique board structure offers a high tensile strength (ILB) essential for long term durability, whilst being developed to minimise board movement reducing any stress being applied to the render system.
