A Look at the UL Guide Information for Through-Penetration Firestop Systems: Angled Penetrations
This category covers firestop systems, which are specific constructions consisting of a wall or floor assembly, a penetrating item passing through an opening in.
Fire Resistive Joint Systems
Description:There is no movement or activation required. These passive systems are mainly used to compartmentalize a fire and keep it from spreading for a period of time long enough that occupants can evacuate the building and so firefighters can perform initial lifesaving tasks. Penetration Firestop Systems Modern buildings are full of various services that travel from room to room throughout a building. Electrical cables, data cables, and plumbing pipes are few of the items that pass through walls as they travel through a building. Engineers try to avoid having these services pass through fire and smoke barriers, but it is usually impossible. When a service must pass through a rated wall, penetration firestop systems are used to ensure the wall rating is maintined.
