Usage/purpose

FZ100 Fire Safe Zone is a fire compartment reinstatement solution for planned and future penetrating services. In the event of a fire, FZ100 will expand and reinstate the compartment line performance where it has been breached by service penetrations.

FZ100 may be located anywhere within a building element, either at the point of construction, or retrospectively fitted. This allows a designer to anticipate future fire sealing requirements, and to integrate FZ100 at strategic points within the building, where subsequent services may be located.

FZ100 product is placed centrally within the flexible wall cavity, allowing both high service movement, and an uninterrupted aesthetic appearance on all visible wall faces. It offers a quick and easy installation with zero potential waste.

Alternatively, FZ100 can be installed horizontally in an opening or in a shaft into floor elements, such as concrete, AAC or CLT.

FZ100 is ideally suited for use in modular application, where services may be located after the construction of the compartment.


Typical areas of use include: health and leisure facilities, schools, universities, modular construction, commercial buildings, hospitals, retail and industrial units, train stations, nuclear power plants, etc...
