When Should You Use a Fire Stop Collar in Construction?
A fire stop collar is required whenever combustible pipes pass through fire-rated walls or floors. These devices are critical in maintaining the integrity of fire barriers, especially in commercial and high-rise buildings. During a fire, the collar’s intumescent material expands to seal the space left by a melting plastic pipe, effectively blocking flames, smoke, and toxic gases. Fire stop collars are quick to install and come in various sizes for PVC, ABS, or other plastic piping. They are an essential part of passive fire protection systems, and compliance with fire codes often depends on using them properly.
