3M™ Fire Barrier Rated Foam FIP 1-Step

3M Fire Barrier Rated Foam FIP 1-Step

3M Fire Protection introduces 3M™ Fire Barrier Rated Foam FIP 1-Step, a breakthrough technology that satisfies the International Building Code for passive fire protection. 3M FIP 1-Step gives contractors an outstanding alternative to caulks, mineral wool, bricks, runny ineffective foams, and enables firestop installations to be completed up to three times faster than traditional methods.1

3M™ Fire Barrier Rated Foam FIP 1-Step is like no other firestop foam. With a non-runny formula, the foam stays in place and expands up to five times. The foam is similar to many two part epoxy sealants, but its one-step application means that trips up and down the ladder are reduced. As 3M FIP 1-Step expands, it creates a seal around cables, conduit and cable trays, so complex installations can be tackled fast, with less clean up. It can be installed in both vertical and horizontal applications without running or sagging. Contractors who have struggled with irritating mineral wool, bricks and caulk will appreciate the simple installation — some installations can even be completed from just one side of the opening.

With these ease-of-use advantages, 3M FIP 1-Step helps save time and money — in fact, the more complex the opening the greater potential for savings. 3M FIP 1-Step is easier on a contractor’s purchasing team, with less product to order, keep on hand, and move between sites. 3M™ Fire Barrier Rated Foam FIP 1-Step is UL tested and listed for a broad range of applications and meets the International Building Code for passive fire protection. To meet these standards, the foam passed rigorous testing, including the ASTM E 814 fire test which includes the difficult "hose stream" test.

"This 3M technological breakthrough combines a foaming technology and a delivery system to create a solution that satisfies code officials, UL and most importantly, our customers and users," said Ernie Schmidt, Technical Service Specialist, 3M Fire Protection Products. "Development of a true firestop foam has been a long quest for many manufacturers, and 3M is proud to introduce this innovative product."
