A building's passive fire protection system is like a silent guardian. It works well because of many details, like sealing holes. Pipes and conduits passing through walls or floors can let fire and smoke spread. This is why firestop collar installation is crucial. These devices keep the fire rating of the assembly they protect. If installed wrong, it can risk lives and property. This guide shows you how to install UL Classified Pipe Collars the right way. We'll cover everything from understanding the classification to making sure it's done right. You'll learn how to plan, follow codes, and do each step with confidence. By following this guide, your penetration seals will work as they should. It makes a weak spot into a strong part of your building's defense. Key Takeaways Correct installation is essential for maintaining a wall or floor's fire rating. Firestop collars seal penetrations to prevent the spread of fire and smoke. This guide provides a professional, step-by-step method for a code-compliant seal. Proper planning and verification are just as important as the physical installation. Using the right materials and techniques ensures the system works as designed. Understanding UL Classified Pipe Collars A UL classified pipe collar is more than just a ring of material. It is a tested and labeled life-safety device designed to maintain a fire barrier. Using the correct, certified product is the foundation of any safe and code-compliant installation. This knowledge ensures you select the right collar for the job and understand why cutting corners is never an option. What Are Firestop Pipe Collars? Firestop pipe collars are devices installed where pipes, conduits, or cables pass through fire-rated walls, floors, or ceilings. Their sole purpose is to seal the annular space—the gap between the pipe and the opening in the structure. They typically contain intumescent material or firestop sealant. In a fire, this material expands or hardens. This action creates a charred seal that blocks flames, deadly smoke, and toxic gases. This process is a critical part of a penetration firestop system. It restores the integrity of the compromised fire barrier, containing the fire to its area of origin. Why UL Classification Matters for Fire Safety You cannot assume any collar will work. Building codes require firestop products to be listed and labeled by an approved testing agency, like Underwriters Laboratories (UL). Using an unclassified or improperly specified collar voids the fire-resistance rating of the entire assembly. It creates a false sense of security and a real liability.…
