Finishing fireplace
Combustible materials, such as wallboard, gypsum board, sheet rock, drywall, plywood, etc., may make direct contact with sides and top around 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.
