Restrict the spread of fire in plasterboard partitions.
ROCKWOOL Intumescent Putty Pads have been developed for use in plasterboard partitions that have been partially penetrated by electrical socket boxes. They are designed to maintain acoustic integrity and fire resistance.
Intumescent Putty Pads are manufactured from a red non-setting, flexible silicone based intumescent polymer. They will not harden, crack or dry out with age.
The intumescent properties activate as temperatures reach 200°C, restricting the passage of fire and smoke
