Siniat Tilebacker board has not been tested as part of a system for fire resistance. The board is classified as A2,s1-d0 for reaction to fire similar to other internal plasterboards in the range.

To create system  with a specific fire resistance period, specify internal plasterboards to meet all requirements (fire, acoustic, robustness, height) then include for an additional layer of Siniat Tilebacker board to receive the tiled finish. With a tiled finish, reduce stud centres to 400mm centres. The Siniat Tilebacker can receive tiles upto 60kg/m2 in mass.

Siniat Tilebacker will also contribute to the acoustic performance of the complete system as a consequence of adding mass which may reduce loss of acoustic performance from closer stud centres.
