General benefits:

• Provides fire protection
• Reduces noise transfer
• Pre-cut cross shape ensures hassle free installation
• Low smoke emission
• Maintenance free
• Remains malleable
• Long service life
• Available for singe and double sockets

Fire Rating

Tested in accordance with BS 476:Part 20:1987 and EN 1366-3, PFC Corofil Acoustic Intumescent Putty Pads provide up to 2 hours fire protection.


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.


Intumescent Putty Pads are manufactured from a red, nonsetting, 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.
• Simply replace and secure the face plate.

Under fire conditions the intumescent 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 can also be used for upgrading the acoustic performance of partitions where electrical sockets boxes have penetrated the wall reducing room-to-room noise transfer.


Acoustic Intumescent Putty Pads are available in two sizes to suit single and double gang electrical boxes.
