How to fire stop PVC pipes

Published on: 29 March 2018

When looking for a firestop for PVC pipes, there are a few important things to consider.  Plastic pipes exposed to fire will react differently according to the type of plastic they are made from.  Some will soften and then char as the fire progresses, others will soften and melt.  If not properly fire stopped these pipes may burn out and leave a passage for fire into adjoining rooms and allow a fire to quickly spread.

What products should I consider using?

Fire collars and fire sleeves with intumescent materials are usually used to squeeze the pipe shut, completely sealing it before the fire can pass through.

Because different types of plastic can react to fire in different ways, you must ensure the fire collar you choose is tested and approved for the type of plastic or make of pipe you are using.  Not all collars will be effective for all types of plastic pipe.  Some collars can only be used on one or two specific types of plastic, others are more versatile.
