Envirograf ISPC Collars protect new and existing uPVC pipes from smoke and fire, a lightweight alternative to heavy industrial pipe collars. The size allows for retrofitting pipes in hard-to-reach areas, usually in older buildings.

Simply fits around pipes quickly and secures with adhesive tape before fixing to walls with included metal brackets, providing fire protection for up to an hour.

The intumescent material expands during a fire, crushing the uPVC pipe and filling the void to seal against the travel of smoke and fire, for up to an hour. This helps slows down the spread of a fire through a building, aiding evacuation and giving fire services more time to contain, control and extinguish flames.


  • Place ISPC collar around pipe on risk side of room.
  • Remove adhesive backing paper from fixing tab and fasten tab to position collar close around pipe.
  • Make holes in wall and insert plugs Push metal clips over collar with equal spacing between clips
  • Put screws through clips and fix.
