A Firestop Putty Pad provides acoustical sealant for wall penetrations in the form of a release lined pad that is ease to apply to electrical boxes or other penetrates. The pad is conveniently sized to fit standard single or double gang boxes with no cutting or piercing required. Faced on both sides with a poly liner, Firestop Putty Pads are easily applied with no mess or excessive residue.

Firestop Putty Pads may also be used through penetrations for wire, cable, etc. Strips of the pad may be cut off and packed around any wall opening. Pad strips may also be applied to penetrate in a mortar system to create a firestop, as well as to absorb movement due to expansion and contraction or resonate vibration. No other product is as easy and versatile to use, and has tested and proven fire and acoustical resistance.

If membrane is to be installed after pad installation, overlap front edge of box so that putty will be compressed around edges of box as wallboard is installed. Cut slits in pad to fit around conduits or cables.

Cleaning and Maintenance:

Remove excess material from all contact surfaces immediately. Clean hands or skin using a water-less hand cleaner. When using water emulsifiable soaps, apply soap and work over areas of the skin contact prior to applying water.
