& Answer Fire
I hear the term
Fireblocking used by builders, can you explain exactly what this means?
Fireblocking is defined by the International Building Code as the use
of approved building materials installed in concealed spaces to resist
the migration of fire and hot gases.
The overall objective
is to stop the extension of fire and hot gases through penetrations in
walls and floors AND to
block the free passage of fire and hot gases within a concealed space.There
are a great variety of products and
materials that will accomplish both aspects of this fire safety objective.While
there is still a need for some develop-
ment to determine what is most effective, there is no doubt about what
is not effective:leaving penetrations and
concealed spaces unprotected or insufficiently protected, thereby exposing
occupants to the risk of tragic failures
we have already experienced from the not-so-distant past.
