They are applied to the back surface of the box, as well as the three sides that are away from the stud. How are they used? Putty pads, as mentioned above, are designed to be applied to the external surfaces of metallic and nonmetallic boxes. The pads are now used primarily to overcome certain restrictions on the number and placement of electrical boxes in rated gypsum wallboard assemblies. Why are they used? Over time, sound deadening has actually become a secondary use for putty pads. He requested that pads be made from a firestopping putty and thus an idea was born.

Sound deadening pads historically have been used in some jurisdictions to meet noise abatement (sound attenuation) requirements between living units in apartments or condos. Let’s discuss the electrical box usage first and then cover their use in through-penetration firestops. We also have used putty pads in a few systems for through-penetrations.
