FINISHING YOUR FIREBOX
There is a wide variety of finishing material
available for your firebox from formal wall
treatments with marble and mantels, to rustic
wood paneling, stone or brick.
IT IS IMPORTANT THAT THE BLACK FACE
OF THE FIREBOX NOT BE COVERED WITH
ANY TYPE OF COMBUSTIBLE MATERIAL.
Non-combustible facing materials such as
marble, brick, or ceramic tile may overlap the
black face of the firebox up to the opening on
either side of the firebox. Seal all joints
between the black firebox face and the wall
covering with a heat-resistant material such as
rock wool insulation or mortar. Be sure to
use high temperature adhesive or mortar when
anchoring brick, stone, or tile to the face of
the firebox. Check to see whether man-made
brick and stone are made of non-combustible
materials before using them on the face of the
firebox. Some of these products contain
combustible materials. Combustible wall
coverings such as paneling or wallboard may
not overlap the black face of the firebox. The
space between the wall covering and the
firebox should be sealed with a heat resistant
material such as rock wool insulation or
mortar.
NOTE: An “L” shaped steel lintel must be
installed across the top of the firebox
opening where facing materials such as
brick or stone is used on the face of the
firebox. It acts as a support/firestop. It
should be attached to the face of the firebox
with screws and sealed to the firebox with a
heat-resistant sealer.
