PFC Acoustic Intumescent Putty Pads are manufactured from a red, non-setting, silicone based intumescent polymer.

Installation is simple:

  • Remove the face plate of the electrical socket box
  • Mould the pre-formed putty pads into the back of the box and around the cables
  • Replace and secure the face plate

Installation Instruction Video:


Under fire conditions, the intumescent putty pad expands to fill the void left by the burnt out electrical socket box, preventing the spread of fire through the plasterboard wall. The intumescent putty pad may also be used for upgrading the acoustic performance of partitions where electrical sockets boxes have penetrated the wall reducing room-to-room noise transfer.


Measurement of airborne sound insulation was made in accordance with BS EN ISO 140-3:1995. Single number quantities were calculated in accordance with BS EN ISO 717-1:1997. The Putty Pads provide a Weighted Sound Reduction Index (Rw) of up to 67dB.
