Expanded Polystyrene EPS
What is EPS
EPS or Expanded Polystyrene is a light weight solid cellular plastic material. EPS is resistant to water, insects and bacterial growth.
Koolfoam EPS conforms to Australian Standards AS/NZS 4859.1 - 2018. Self extinguishing, fire retardant expanded polystyrene. Available as
- Sheeting (standard size 2500 x 1200 by any mm thickness)
- Blocks (5000 x 1200 x 620) and
- Custom shapes and profiles
Benefits of EPS
One of the main reasons EPS is so effective when used as thermal insulation is its high R-value. The R-value refers to a material’s ability to resist heat flow. The thicker the sheet of EPS, the higher the R-value will be.
When it comes to R-value, our polystyrene sheets outperform materials such as weatherboards, plasterboards, concrete slabs, fibre cement sheets and more.
What’s more, EPS is resistant to water, insects and bacterial growth. It’s also lightweight, affordable and quick to produce, making it a practical material for many situations.

Koolfoam Ultra is the new dimension in thermal and building insulation products.
Koolfoam ultra is a type of expanded polystyrene (EPS) with graphite particles in it. These particles both reflect and absorb heat and infra-red radiation. The result is grey EPS with a new level of insulation performance, up to 35% more efficient than white EPS.
R Values for Koolfoam ULTRA
Koolfoam EPS R-value
R-value indicates the thermal resistance of a material. It expresses the ability of a specific thickness of a material to resist heat flow.
The definition of R-value is the reciprocal of the material's thermal conductance (K-value).
The R-value can also refer to an assembly of materials, such as the wall of a building. It can express the combined thermal resistance of an assembly of materials by adding up their individual R-values.
Here are some comparisons of R-values of common building materials:
