ABSTRACT:
The invention relates to a firestop assembly for a pipe, comprising first and second intumescent firestop rings. The first intumescent firestop ring overlies the pipe, and extends along the pipe for a first distance, and the second intumescent firestop ring overlies the first intumescent firestop ring and extends along the pipe for a second distance. The first distance is not equal to the second distance, and the firestop assembly so provided is particularly adapted for firestopping a plastic pipe.
