Yes, HardieBacker 1/4″ Cement Board is deemed noncombustible when tested to ASTM E 136 and can be used in conjunction with other noncombustible materials around a fireplace. This does not mean that clearances to combustible building materials can be reduced by using HardieBacker 1/4″. Clearances to combustible building materials shall be obeyed even if they are protected by noncombustible materials, please refer to your local building and fire code for specific combustible clearance details around masonry fireplaces.
