ROKU® System IWM III plus - EN 13501-2

The ROKU^® System IWM III plus consists of the high performance intumescent material „ROKU^® Strip“, which is wrapped in one or more layers around the plastic pipe or the insulation. The wrap must be inserted into the annular gap flush with the surface. In the event of a fire, the intumescent material expands with high pressure and thus seals the opening hermetically against flames and smoke. For wall installations one wrap on each side of the wall and for floor installations one wrap on the underside of the floor must be provided.
