A firestop collar is a type of fireproof device that maintains the integrity and fire insulation rating of a buildings wall, ceiling or floor which has been penetrated by supply lines. This may be required by fire codes when a wall or floor is penetrated by cables, ducts, pipework, etc. For this situation, the fire rating of the wall or floor can be decreased as the penetration can provide an opening that allows fire and smoke to spread beyond the compartment or room intended to contain it.
Typically, fire collars provide a retaining ring which contains an intumescent compound that expands when heated to a certain temperature. The strong compressive force exerted by the intumescent material forms a fireproof seal, closing off the void, and creating an insulating barrier.
There are different types of firestop collars for different applications (for plastic pipes, copper pipes, general building services, electrical cables, etc), and they can be attached to the wall, ceiling or floor. Other considerations include the firestop collar size, ease of installation, and so on.
