Putty Pads

Quick Overview

Moldable, non-curing, single-component, intumescent pliant in pad form for through-penetration systems. Metacaulk Putty Pads expand when exposed to heat, forming a refractory char that tightly seals to prevent the spread of flames, smoke, and toxic fumes. They are designed for interior use with various penetrations, such as cabling, EMT pipe, and conduit. These putty pads contain no volatile solvents, making them particularly useful in confined spaces or occupied areas, and they do not contain asbestos fillers. Easy to install by hand with no curing time, they adhere to all common building surfaces. Metacaulk Putty Pads help provide a barrier or buffer for energized bus ducts or conduits and protect against vibration and movement. No additional putty material is needed to plug the end of each electrical metallic tube or conduit at its connection to the box. Additionally, they are required by building codes in rated partitions where horizontal separation of opposite-facing electrical boxes is under 24 inches.
