FINISHING THE FIREPLACE
Combustible materials, such as wallboard,
gypsum board, sheet rock, drywall, plywood,
etc. may make direct contact with sides and
top around the fireplace face. It is important
that combustible materials do not overlap face
itself. Brick, glass, tile or other noncombustible
materials may overlap front face provided
they do not obstruct essential openings such
as louvered slots. When overlapping with
a noncombustible facing material, use only
noncombustible mortar or adhesive.
