  2. ZZ® M20

    ETA-10/0431
    System ZZ-Brandschutzstein 200 NE MW

    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.
