Packing is the process and/or the materials used in filling both
service penetrations and
building joints with backer materials as approved components within a
firestop.

Purpose
Packing with inherently fire-resistive materials, such as rockwool or ceramic fibre is intended to protect
sealants that would, on their own, be consumed by the
fire. Lesser packing, such as
foam backer rod or fibreglass are used simply to hold up materials that can survive
fire testing on their own. In both cases, the packing is placed in such a way as to control the exact depth of the materials that top off the seal.
Special care
Proper packing is particularly important with self-leveling sealants. If the packing isn't tight enough, the expensive caulking will drip out of the
hole. If the packing surface isn't straight enough, the thickness of the caulking will be wrong.
If firestopping takes place on
plumbing pipes that have not yet been tested, packing can move the pipes and interfere with the plumbing. It is thus important for the work to be co-ordinated between plumbers and firestoppers.
