摘要

描述 Mechanical pipe through-penetrations in 2 hour fire-resistance rated concrete floor slab with metallic piping, covered through the thickness of the firestops with 25mm thick rockwool pipe covering with foil scrim kraft facing. Running the pipe covering through the firestop maintains the vapour barrier. A weak link in the vapour barrier is the cutting and fitting required around riser clamps. Rockwool, foam glass, calcium silicate, perlite and vermiculite pipe covering can survive a fire test with a hose-stream. Foamed plastic, rubber and fibreglass require either removal or wrapping with an intumescent layer to be sure that as the pipe covering disappears during a fire, the vacated space is occupied by solid matter that can withstand the fire test and hose stream test, all subject to bounding.
