For uPVC pipe over 160mm: Use Fire Collar
- Make measuring points according to pipe size
- Cut fire collar at marked measuring points according to pipe size. - Ben the intumescent side of the collar until it snap.
- Shape the collar to fit the pipe and bevel intumescent edge for close fit.
- Wrap the collar around the pipe and clip the first bracket into slots on both ends.
- Complete other brackets and fit the collar onto wall/slab.
