Hi my question is I have a cast iron pipe going through a cement floor the pipe is a 10 in pipe and the hole is a 13x15 square hole the widest point is 5 " and the smallest point is zero I think that hole is to big to fill with FS 1 product and mineral wool insulation, is there a minimum space to ne up to code thank you nick
Hi Nick:
It appears that UL System No. C-AJ-8143 will meet your requirements. This system utilizes mineral and FS ONE. The annular space between all other penetrants and the periphery of the opening shall be min 0 in. (point contact) and a max annular space in the system shall be 12 in, reference note #2. A copy of C-AJ-8143 may be downloaded from our website: https://www.hilti.com/medias/sys_master/documents/hf4/9140998635550/Approval_document_ASSET_DOC_LOC_254.pdf
