Firestop Putty Pads

These intumescent firestop putty pads provide fire stopping in drywall where plastic socket boxes have been installed. Remove the face plate of the electrical socket box and mould the pre-formed putty pads into the back of the box and around the cables then simply replace and secure the face plate. When a fire occurs, the intumescent pad expands to fill the void left by the melted plastic electrical box, preventing the spread of fire through the drywall. The intumescent putty can also be used for upgrading the acoustic performance of partitions where electrical sockets boxes have penetrated.

Our Putty Pads are used for a fire barrier of up to 2 hours. They are designed as a joint filler and void sealer for use in penetration seals. These Putty Pads are also designed to remain flexible allowing for thermal and mechanical movement of services around complex and irregular shapes through walls or floors, this is a nonsetting compound.
