Expanded polystyrene (EPS); can be used in various different ways:

To create different levels of the finished concrete level of a slab especially from internal to external thresholds, or where steps are required;

Special designs in soffits of flat slabs;

Recesses (voids) for lighting or other services required in the soffit of a slab. Sagex polystyrene is manufactured in a range of grades for a variety of applications to suit customer requirements:
  • 16D is used in building insulation applications as core material for panels, cold room insulation, packaging and flotation.
  • 24D and 32D are used in applications which require greater cross-breaking and compressive strengths, such as in floor and roof slab insulation, and where a better finish is required, such as in display applications.
  • FR Grade is treated with a flame retardant and is ideal for industrial applications where fire safety requirements must be met. As the material shrinks away from ignition sources without further burning, it is suited to exposed applications. The above are available in FR grades.
  • X Grade is a low-density material used mainly in void forming and packaging.
