Effectively fill spaces caused by pipes and cables traveling between walls with 3M’s through penetration products. Whether you need preformed plugs or the flexibility of expanding foam, sealant, or moldable putty, 3M has you covered. 3M products are designed with a focus on easy application and excellent adhesion—because when it comes to fire protection, there’s no room for doubt.

Fire Barrier Rated Foam FIP 1-Step

This ground-breaking firestop foam stays put in vertical and horizontal applications without running or sagging. Because it’s a one-step application, there’s less product to order, keep track of and haul. Even complex firestop installations—like cable bundles, conduit banks, and cable trays—can be finished more than 3X faster, saving time and money. It’s UL Listed for a broad range of applications and meets the International Building Code for passive fire protection
