Mixed penetration seal up to EI 120 for rigid walls, rigid floors and flexible walls. Through penetration firestop system for electrical cables, telecommunication cables and optical fibre cables, conduits, P-HD ducts for fibre optic and waveguide cables as well as combustible and non-combustible pipes.

• Medium-sized and large penetration seals with a medium to high density of penetrating elements
• Through penetration firestop systems with frequently changing penetrating elements
• If the ZZ® 230 Fire Protection Block is installed transversely (seal thickness 144 mm) a through penetration firestop system of fire resistance class EI 60 can be produced.
• If ZZ® 230 Fire Protection Block are installed lengthwise (penetration seal thickness 200 mm), a fire resistance class up to EI 120 can be assigned to the through penetration firestop systems (depending on the existing penetrating elements and, if necessary, with the use of ZZ® 451 Fire Protection Wrap).
• In areas with a high number of penetrating elements, ZZ® 230 Fire Protection Block can be used for closure.
