Application

When electrical sockets and switches are installed in dry lining  partitions, the original fire rating of the partition is compromised.  Fitting Putty Pads will reinstate the fire rating of the partition for  up to two hours (depending on the partition fire rating)   preventing the passage of smoke and flames in a fire, and sound  and air movement during service life, through the electrical  socket, into the cavity. 

Putty Cords for fire sealing services 

The putty cord is designed to be easily fitted around service  penetrations where the gap around the services is very small, or  there is no gaps at all so a conventional fire rated sealant is  impossible or difficult to fit due to the required depth and  backing material. The putty cords are fitted covering the gap around the services and do not need to fill the gap to the required depth.
