Sovereign Putty Pads restore any loss in fire rating of a party or partition wall that has had an electrical socket or switch put in. The pads fit inside the back box and in the event of a fire would expand to fill any gaps in the void and give protection from smoke. They also reinstate the sound insulation.
They come in 2 sizes; a single back box (170mm x 170mm) and a double (230mm x 170mm), both supplied in boxes of 20.
The use of these pads is now compulsory as per the 2006 Edition of the Building Regulations Approved Document Part E and B Section 7, 7.12b
Form Supplied: Conoured putty in film
Pack Sizes: 20 per box
Pad Sizes: 170mm x 170mm (Single) & 230mm x 170mm (Double)
The pads are non-setting and flexible and will not harden, crack or dry out with age. The Intumescent properties will activate as temperatures reach 200oC thus restricting the passage of fire and smoke.
