Innovation in Mechanical Trade Firestop System Much of the innovation in plastic pipes can be seen in the Mechanical trade for plastic pipe penetrations. The traditional practice of applying Firestop to plastic pipes have been firestop sealants. This not only becomes tedious to install at sometimes, but it also is not inspection friendly. This is where we see industry innovating the Firestop devices for plastic pipes by introducing Firestop systems which can be easily cast in during the stage of roofing. When it gets cast in the roof at the roofing stage, a piping contractor can later locate these devices easily visually and then pass the pipes by simply opening the lid of the devices. At the same time, it becomes very easy for an inspector to visually look at such devices cast in a roof without touching it. Please find below the picture of one of such devices.
