Knauf Putty Pads
Knauf (FR) Putty Pads are an easy to apply fire and sound rated sealant supplied as a non-setting putty. The pad is hand workable, re-useable and re-serviceable due to its non-setting properties.
When electrical sockets and switches are installed in dry lining partitions, the original fire rating of the partition is compromised. Fitting Knauf (FR) Putty Pads will reinstate the fire rating of the partition for up to two hours (depending on the partition fire rating) and prevent the passage of smoke and flames in a fire, and sound and air movement during service life, through the electrical socket, into the cavity.
Knauf FR Putty Pads are shaped for use on both single double electrical sockets installations in dry lining walls. The pads are supplied in a cross shape for internal installation in a socket.
