Description
CEMBLOC® DryBloc® TG4 is available in thicknesses 18mm, 20mm and 22mm. The DryBloc® TG4 is an A1 fire rated solution. CEMBLOC® DryBloc® TG4 tongue and groove floor board (T&G) profile, reinforced cement fibre board, reinforced by natural minerals on both sides boasting an impressive loading capacity of up to 7kN/m² (max weight test rig could test - based on DryBloc® TG4/22). These dry-fit screed replacement panels at only 18mm , 20mm and 22mm thick offer minimal floor height and save on drying times when compared to traditional screeds.
DryBloc® TG4 is exceptionally unique as it offers an outstanding thermal conductivity value 0.216 W/mK when used in conjunction with underfloor heating systems. DryBloc® TG4's high density provides excellent airborne sound performance through many types of separating floors. It is a high performing multipurpose building board that’s designed purposely to provide fireproof, acoustic and waterproof protection, with very high dimensional stability which makes it a high performance alternative to Gypsum and Cement Particle for any construction type.
DryBloc® TG4 is superior flooring board with exceptional dimensional stability of (<0.19%) compared to alternatives such as chipboard, gypsum fibre and cement bonded particle board.

Note:
- Concentrated load is applied over an area of 300mm x 300mm.
- Allowable maximum deflection is limited to l/250 of joist spacing.
- UDL, Uniform distributed load.
- CL, Continuous load.
- For spans above 450mm we recommend DryBloc® TG4/22, for spans below 450mm, DryBloc® TG4/18-20mm are more than suitable

Profile.
Our suggestion is to place the smooth side facing up. Make sure to maintain consistency in the orientation of each board during installation.
Areas Of Use.
- Compatibility with Routed Insulation for Underfloor Heating: This cement fibre board can be used in conjunction with routed insulation for Underfloor Heating (UFH) applications, offering a thermal conductivity of 0.216 W/mK.
- Versatile Flooring Options: It is suitable for installation on both timber and steel joisted floors, providing flexibility for various construction needs.
- Integration with Metsec Style Decking: The board can also be incorporated into a buildup on Metsec-style decking, enhancing the overall structural performance.
- Joist Spacing and Thickness Recommendations: This cement fibre board is designed to span joists at a spacing of 450 mm or less when using 18 mm thickness. For joist spacings above 450 mm, we recommend using the 22 mm thickness to ensure optimal support and stability, while also being mindful of the overall loading capacity.
