ABSTRACT:
The invention relates to a fire resistant material based on an elastomeric foam. The invention further comprises a system for sealing off, at least during a fire taking place adjacent the wall, in an at least virtually entirely fire-tight manner, an open extending through that wall through which a transporting device comprising for instance a cable, duct or pipe has been fed, the system being provided with elements manufactured from a fire resistant material which expands under the influence of temperature increase. In addition, the invention extends to a wall in which such a system has been incorporated and a method for scaling off an opening extending through a wall through which at least one transporting device such as a cable, duct or pipe has been fed.
