RSS Wallboard

RSS boards are made of high-performance waterproof extruded polystyrene, it has a 1mm coating on either side comprising a glass fiber mesh embedded in a polymer-cement mortar.

The boards should be stored dry and flat. Slight bowing caused by incorrect storage or transport, for example, is not permanent and does not represent a technical defect. Slight curving can be rectified through storing the boards flat.

RSS Waterproofing Membrane

RSS Waterproof Fabric Membrane is a polyethylene waterproofing membrane with spun polypropylene anchor webbing on both sides to anchor the membrane into thin-set mortar. It is primarily used to create a vapor and waterproof barrier to protect the integrity of building structures from moisture, mold and decay, and generally used in conjunction with tiled surface of showers, steam rooms, and wet rooms. Tiles can be installed directly onto RSS waterproof fabric membrane using a layer of modified or unmodified thin-set mortar.
