Featured Product

This groundbreaking 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.
