Standard Polystyrene Densities & Applications

Our polystyrene sheets & blocks are manufactured in the following densities:

  • Low Density Polystyrene : 12 kg/m3 to 14 kg/m3
  • Medium Density Polystyrene: 15 kg/m3
  • High Density Polystyrene: 20 kg/m3
  • Highest Density: 24 kg/m3 to 30kg/m3

Polystyrene densities affect the price & compressive strength of polystyrene. The lower the density, the cheaper the polystyrene sheets & blocks are!

  • Low density polystyrene is good for general use purposes where no compressive strength is required.

  • Medium density polystyrene is denser and is suitable for brick cavity wall insulation applications.

  • High density polystyrene has a high compressive strength and is mostly used for insulation applications below concrete floor slabs and for above concrete roof insulation applications.

  • Highest density polystyrene has a very significant compressive strength and is used where very heavy loading requirements are needed.

If you need help choosing a density, email us on or call us.
