Protecta Putty Pads for Acoustic & Fire Stopping
The Protecta Putty Pad has been designed to maintain the fire resistance of gypsum walls where these are breached by electrical switches and sockets, and tap water wall boxes.
The Putty Pad is a non-setting flexible intumescent pad based on a silicone polymer with additional fire retardant additives. The Putty Pad can be fitted inside or on the outside of the sockets or wall boxes and in a fire they form a robust fire resistant char that prevents burn through at the location of electrical or pipe penetrations. Only 1 pad or 1 kit is required for each box and these can be any combination of internal/external fix to allow more flexibility when fixing drywall linings on second fix.
The Putty Pad can be supplied in 4 sizes to suit single or double electrical boxes and a kit for tap water wall boxes, and are supplied on a quick release paper. The Putty Pad is also an ideal product for air-sealing around penetration openings.
Protecta FR Putty Pads have been tested according to BS EN ISO 140-3:1995. Usage of any backing material is optional, due to the tests being conducted with Protecta FR Putty Pads only.
