Cable and pipe penetrations for walls and ceilings in Löhne — approved, tested, documented. Promat, Hilti, Würth · S30 to S90 · existing stock, new build, retrofit.

The system depends on opening size, occupancy density and wall type.
Intumescent collar for plastic pipes, mineral wool insulation for steel — system-dependent, per approval, documented in the penetration plan.
