  • Suitable for the GTEC Shaftwall systems and for fire protection.
  • It is also suitable for use in areas where there is moisture present. The board is thicker, stronger, harder and heavier than standard plasterboards, and has superior fire resistance, sound insulation and impact resistance.


Siniat Fire Core Board is a high-strength fire protection and moisture-resistant plasterboard for use in GTEC Shaftwall systems, steelwork and fire encasement. For the protection of shafts and voids in multistorey buildings, preventing the continuous spread of fire, and enabling fire-stopping.

Features and benefits:

  • Provides up to 120 minutes' fire performance when used with GTEC Shaftwall Fire Protection system.
  • Lightweight friction fit framing system is fast to install, and uses less materials than other systems.
  • High-strength system resists pressure changes likely in deep shafts and voids.

Technical characteristics:

  • Fire, acoustic and duty performance dependent on the whole system. See Siniat Drywall Manual for Siniat system performances.
