Product Description
ROKU® Strip is a flexible, intumescent material on the basis of
expandable graphite, which expands under high pressure when heat is
applied.
Special feature: A pressure-resistant mass is created in case of fire.

Application Areas
■ Fire protection doors of wood, steel or aluminium
■ Glazing, facades
■ Safety storage cabinets, safes
■ In drywall construction: inspection flaps, separating walls and floor constructions
■ Component joints, heat insulation elements
■ Fire protection flaps and cable penetrations
■ Pipe insulation systems
■ Gas stop valves, pneumatic drives
