ROCKWOOL Intumescent Putty Pads are manufactured from a non-setting, flexible silicone-based intumescent polymer that possesses a low smoke emission. Should there be a fire, these Intumescent Putty Pads will activate at a temperature of 200°C where the pad will expand to fill the space left by burnt out socket boxes, creating a seal that will prevent the passage of fire and smoke. 
 
ROCKWOOL Intumescent Putty Pads offer up to 2 hours* fire resistance, ensuring protection against fire and smoke passage.  
Available for single and double sockets
Tested acoustic performance
