TETRiS – Revolutionary Thermal Insulation block and beam system

TETRiS – Revolutionary Thermal Insulation block and beam system

Why use TETRiS instead of block and beam?


Gone are the days that heavy concrete blocks are the only solution for block and beam flooring systems. TETRiS is a revolutionary insulation block and beam floor system, designed to replace traditional concrete blocks and offer outstanding thermal and structural performance. The system consists of large, lightweight, ultra high compressive strength insulation blocks that sit on and between standard pre-stressed concrete floor beams. The blocks are then covered with a structural concrete topping, to produce a super insulated floor with the highest possible Green Guide rating of A+.

What are the benefits of using TETRiS instead of block and beam?

  • Faster floor construction (up to 16x less blocks to install)
  • Supplied to site in floor specific quantities
  • Reduces the number of beams required
  • Produces a floor with zero cold bridging
  • BRE Green Guide A+ rated system
  • 3x more Code credits awarded
  • 100% recyclable
  • More cost effective
