Stove boards are essential wood burning accessories that can be used beneath wood burning appliances or on the wall behind them to protect floors and walls from intense heat. The HY-C type 2 UL1618 stove board provides non-combustible thermal and ember protection for floors and walls from the intense heat, hot coals, ashes and soot that wood burning appliances can produce. The construction is embossed printed steel and 1/2 In. thick, specially formulated fiber board backing.
