Application/Installation

Firstly the face plate of the electrical socket box should be removed. All surfaces must be clean, free from dirt, grease and other contamination. Then remove the backing paper from one side of the pad and insert the pad into the socket back box so that the pad completely covers the back and sides. Make a slit to allow the wires to pass through the pad. The face plate should then be replaced and secured back to the socket box. Quelfire Intumescent & Acoustic Putty Pads are suitable for sealing both single and double socket boxes.

Composition

The Quelfire Intumescent Acoustic Putty Pads are manufactured from a red, non-setting silicone based intumescent polymer.

Performance

Acoustic
The Quelfire Intumescent Acoustic Putty Pads can also be used for upgrading the acoustic performance of partitions where electrical socket boxes penetrate the wall reducing the room-to-room noise transfer.


Liquids

Durability
Quelfire Intumescent Acoustic Putty Pads are expected to last the lifetime of the service installation.
