Product Description
Protect critical wall openings with industry-leading firestop performance using 3M™ Fire Barrier Moldable Putty Pads MPP+. These one-part, ready-to-use intumescent putty pads are designed to help prevent the spread of fire, smoke, and toxic gases through electrical outlet boxes, wall penetrations, and other fire-rated assemblies.
The pliable material easily molds by hand without mixing or special tools, providing excellent adhesion to a wide variety of construction materials. Unlike traditional sealants, the pads remain flexible, will not dry out or crumble, and are re-enterable for future maintenance or cable additions.
Ideal for commercial, residential, and industrial construction, 3M™ Fire Barrier Moldable Putty Pads help maintain the integrity of fire-rated walls while also reducing sound transmission through wall assemblies.
