Fire protection collar

The ROKU® System EC Endless Collar consists of the high performance intumescent material „ROKU® Strip EM“ or „ROKU® Strip“ (for U/U applications), which is wrapped in one or more layers around the pipe or the insulation and fixed with a stainless steel strap and hooks at the wall or floor. 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 pipe collar on each side of the wall and for floor installations one collar on the underside of the floor must be provided.
