Polylack KG spackel (310 ml)

This seal consists of rock wool plates and a special kind of putty that, in case of fire, expands to several times its original volume. Thanks to this, it prevents flame propagation by cutting even thick plastic pipes and filling rising gaps, similarly to cable penetration. Among others, this system can be used for the fire-protection closing of plastic pipe bushings and cable penetration with or without protective metal pipes, as well as for filling gaps.
