How does a firestop collar work?
Promat fire resistant collars crush plastic pipes during exposure to fire. This intumescent material forms an insulating barrier which reduces heat transfer between compartments and closes off any gaps to stop the spread of smoke, fire and gas. ...
What is pipe collar?
Makes it possible to connect the main pipe to mounted-in drain pipes, without other indents or holing. The pipe collar fits tightly round the pipe end at the same time as it serves as a cover. ... In this way the outside and inside of the pipe is protected from the concrete.
