Firestopping a plastic pipe through an oversized hole

QF2 Fire Protection Compound and Intumescent Pipe Wrap

Firestopping a plastic pipe through an oversized hole

The process for firestopping a plastic pipe through an oversize hole in a concrete floor:

  1. Use the Quelfire MW Slab as a Shuttering Slab to the lower side of the concrete floor.
  2. Install the QWW CE Marked Intuwrap around the plastic pipe. Making sure the right size Intuwrap is used for the right size pipe.
  3. Mix the QF2 Fire Protection Compound with water and pour around the QWW CE Marked Intuwrap.
  4. The QF2 Fire Protection Compound expands on curing and therefore locks the QWW Intuwrap in place around the pipe.
