Through Penetrations

3M has a strong portfolio of products (e.g. fire barrier sealants, devices, mortar, wraps, foam, putty, kits) for use in tested and listed through-penetration firestop systems. These products are designed to help prevent the spread of fire, smoke and toxic gases through openings in fire-rated construction (e.g. walls, floor/ceilings and floors) and smoke barriers/partitions.

In addition to providing up to 4-hour protection in tested and listed systems for through penetrations and blank openings, some of the products also offer additional protection benefits such as cable management, acting as a barrier to water leakage, acting as a cold smoke/air barrier and/or reducing airborne sound transmissions.
