Fire resistance rating
To help prevent the rapid spread of fire
within a building, certain walls, floors
and joints are required to meet a
specific fire resistance rating — the
period of time during which a building
6 9 component has been tested to confine
a fire or continue to perform a struc-
tural function or both. Through-pen-
etrations and joints created during the
construction process require the instal-
lation of firestop systems in order to
bring the wall or floor back up to its or
orginal fire-rating.
Firestopping
It is essential that every penetration
2 or joint in a fire-rated wall or floor is
4 adequately protected by sealing — or
“firestopping” — such that the building
componet is restored to its original
fire-rated condition in order to maintain
compartmentalization. The quality and
1
5 excellence of Hilti Firestop Products
help ensure that fire, smoke and toxic
gases are contained to reduce the
tragic loss of human life and damage
to property.
