Product Description
A Firestop Acoustical Putty Pad provides acoustical sealant for wall penetrations in the form of a release lined pad that is easy 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 Acoustical Putty Pads are easily applied with no mess or excessive residue.
Firestop Acoustical 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 wall membrane is in place, pack putty into gaps between box and wallboard slightly overlapping inner wallboard surface. 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.
- Press pad to surface of top, bottom and sides of box. Trim excess at corners and apply to conduit fittings connected to the box. As required, putty may be packed into insides of conduit fittings to prevent passage of smoke. Poly liner may be left on the back of the pad or removed.
