and is also used to fill voids in joint spaces to provide the neces-
sary thermal resistance in fire-resistant joint systems (which are
discussed later in this book). Note that materials made from glass
fiber are not classified as “mineral wool,” so materials made from
glass fiber cannot substitute for mineral wool in firestop systems.
For additional information related to this topic, see the discussion in
the “Miscellaneous items” section of the book, under the subhead-
ing “Mineral wool versus mineral fiber.”
FIRESTOP APPLICATIONS
Firestop applications can be segregated primary into two main
