AHR Expo 2019: HOLDRITE HydroFlame Firestop

Discovered on the floor at the AHR Expo 2019, this product is a UL-listed water, smoke and firestop device for concrete buildings. The sleeves are installed in the floors between stories and provide a pathway for plumbing pipes, electrical conduits and other utilities. Meets code requirements for firestops with an expanding material that closes off gaps between piping and the sleeve when it gets hot, stopping fires for up to three hours. A mid-body seal stops smoke, as required by code, and also prevents water penetration from affecting floors below.
