RCM Y-Wall is a high-quality, flexible calcium silicate cement building board designed for use as an external sheathing board in various construction applications. It offers excellent fire resistance, moisture resistance, and thermal performance, making it ideal for use in timber frame, steel frame, and modular construction. Y-Wall is lightweight yet robust, providing structural stability and durability while being easy to handle and install. Its compatibility with different types of cladding systems and finishes makes it a versatile choice for enhancing the safety, efficiency, and longevity of building envelopes in both residential and commercial projects.

How is RCM Y-wall installed?

RCM Y-wall is installed by fixing it directly to the building’s structural frame using appropriate screws or nails. It should be installed with a gap between the boards to allow for movement, and joints should be sealed using jointing tape or sealant to ensure a weather-tight finish. The installation should follow the manufacturer’s guidelines for best practices.

Does RCM Y-wall provide acoustic insulation?

While RCM Y-wall is primarily designed as a fire-rated and moisture-resistant sheathing board, it does offer some acoustic insulation properties due to its density. It can help reduce sound transmission when used in wall assemblies, improving the overall acoustic performance of a building.

How does RCM Y-wall handle moisture?

RCM Y-wall is highly resistant to moisture, making it suitable for use in wet or humid environments and external applications. Its calcium silicate and cement composition prevents water absorption, reducing the risk of swelling, warping, or degradation over time.
