External walls: RCM Renderflex is a high-performance cellulose fibre cement building board designed specifically for use as a render carrier board in external wall applications. Its strong and stable construction makes it ideal for supporting various render finishes, ensuring a smooth and durable surface. Renderflex offers excellent resistance to moisture, fire, and impact, making it suitable for a wide range of environments, including residential, commercial, and industrial buildings. Its versatility allows it to be used with timber or steel frame structures, enhancing the durability and lifespan of the façade system. Easy to install and handle, RCM Renderflex is a reliable choice for achieving high-quality render finishes.

How is RCM Renderflex installed?

RCM Renderflex is installed by fixing it directly to the building's structural frame using mechanical fasteners. The boards should be installed with a gap between them to allow for movement, and joints should be sealed with an appropriate jointing tape to ensure a continuous and watertight substrate for the render system. It is recommended to follow the manufacturer’s installation guidelines for best results.

How does RCM Renderflex handle moisture?

RCM Renderflex is moisture-resistant and can withstand exposure to weather without degrading. Its cement-bonded composition prevents moisture absorption, reducing the risk of mould growth and ensuring the longevity of the render system.

Does RCM Renderflex provide acoustic insulation?

While RCM Renderflex is primarily designed as a render carrier board, it does offer some acoustic insulation properties due to its density and thickness. For enhanced soundproofing, it can be combined with other insulation materials within the wall system.
