  • Beam and Block Flooring


  1. Good thermal performance

    Improves the thermal perfomance for ground floors and provides acoustic performance for internal floors.  

  2. Fast building blocks

    Toplite blocks are light and easy to handle, decreasing build times.  

  3. Easy to work

    Cutting, chasing and finishing are all straightforward and quick to achieve using standard tools.  

Application Details

Floor blocks are suitable for use in suspended ground and internal floors in conjunction with precast concrete beams.

They are light and quick to install, and provide effective sound and thermal insulation for ground and internal floors meeting the requirements of the Building Regulations.

The use of Toplite Floor Blocks can achieve economy in the overall design of the floor. Firstly by a reduced dead load, secondly, the size of the block allows much more flexibility in beam spacing allowing fewer beams to be used.

Transverse Load
The blocks have been tested spanning 440mm and 535mm to sustain a point load of a 3.5KN transferred via 100mm x 100mm steel plate.

Thermal Insulation
The use of Toplite Floor blocks may reduce the amount of ground floor insulation needed compared to the use of denser floor blocks. This will be further improved when used in combination with Toplite Foundation blocks.
