Multitube fireproof intumescent tape does not require a supporting structure, therefore it can be mounted directly on the pipe at its destination. The tape is wrapped directly on the pipe or on the outside of the pipe insulation, depending on the type of pipe and type of insulation (for details see ETA-15/0511). For pipes running through the floor, wrapping with a fireproof tape can be performed both before pouring the floor or part of the floor with concrete mortar, and when pouring the floor or part of the floor with concrete mortar. For pipes running through a wall, wrapping with a fireproof intumescent tape can be done while the wall or part of it is built. For pipes led in a shaft or in technical openings, wrapping with a fireproof intumescent tape should be performed before walling them up. For drilled holes, Multitube fireproof intumescent tape should be wrapped and fastened around the pipe outside the opening and inserted into the floor in the partition or placed on both sides of the bulkhead. Fixing the fire-resistant tape on the pipe can be done with an electrically clamped band or with a silver adhesive tape.

A mounting clearance (u = approx. 25 mm) for penetration seals using Multitube fireproof intumescent tape is only required due to the space required for its installation when drilling holes in existing partitions.

We install fireproof intumescent tapes in the walls along the axis of the wall or symmetrically on both sides. In floors, a fireproof intumescent tape should be installed 15 ± 5 mm from the bottom of the floor.
