TONGUE & GROOVE FLOORING BOARD

DryBloc TG4 18/22mm

Flooring applications such as wet underfloor heating, acoustic, screed board and tiling.

Drybloc TG4 has been designed as the utopian floorboard, for any flooring applications such as wet underfloor heating, acoustic, screed board and tiling.

High Density Overlay Board as a wet screed replacement and/or for acoustic & underfloor heating applications

Description

Cembloc Drybloc TG4 is available in thicknesses 18mm, 20mm and 22mm. The Drybloc TG4 is an A1 fire rated solution.  Cembloc Drybloc TG4 T&G profile, reinforced cement fibre board, reinforced by natural minerals on both sides boasting an impressive loading capacity of 7kN/m² (max weight test rig could test). 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’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.

Common DryBloc TG4 Questions

  • Can I Use Plywood Instead?

    No. Under British Standards BS 5385 Part 1, plywood is not a suitable substrate for the direct fixing of wall tiles, therefore when tiling onto walls, a tile backer board is required. However, tiling onto plywood overlaid floors is acceptable under British Standards. 


  • Do I need to use CemBond on the DryBloc TG4?

    Yes, CemBond Max Strength Sealant/Adhesive is necessary for all Cembloc installation guides to protect and adhere the boards in place.


  • Which way round do I lay DryBloc TG4?

    DryBloc TG4 boards should be laid with the print side up, with the text located on the top corner of the board. If the text cannot be found, the boards have a smooth side (the printed side) and a slightly textured side to the rear. Whilst it does not matter which side is tiled onto, it is recommended to tile onto the smoother surface.


  • What Is DryBloc TG4 made of?

    DryBloc TG4 is a fibre cement boards made from organic fibre, sand, cement, and water. The mixture of these ingredients is critical to produce a strong, firm, water-resistant board suitable for heavy tiles and moisture.


  • Benefits of DryBloc TG4 vs Chipboard?

    There are several reasons why fibre cement flooring may be a better choice than chipboard for flooring applications. Fibre cement is a more durable and long-lasting material than chipboard, making it unlikely to warp, crack, or break over time. It is also resistant to weathering, rot, and insect damage, making it a better choice for outdoor or wet environments. Fibre cement is also non-combustible and can be used in fire-rated applications, whereas chipboard is combustible and should not be used in fire-resistant construction. Fibre cement flooring is also available in a wider range of colours, textures, and styles, giving you more design options to choose from. Overall, fibre cement is a more versatile, durable, and reliable material for flooring than chipboard.


  • Do I need to Prime?

    For a solid foundation for your tiles, it is recommended to prime DryBloc TG4 Tile Backer Boards with Cembond SBR to improve tile adhesion and adhesive open times.


  • How do I cut DryBloc boards?

    The use of a Polycrystalline blade is always recommended to speed up the process and efficiency.


  • What glue do I use with DryBloc TG4?

    We recommend using CemBond Max Strength Sealant/Adhesive along with Cembloc FCB screws when installing DryBloc TG4.
