Polystyrene cellular plastic from Koolfoam

Polystyrene is a lightweight cellular plastic foam material composed of carbon and hydrogen atoms.
It is derived from petroleum and natural gas by-products. Moulded EPS does not involve the use of CFCs. Polystyrene is sanitary, sturdy, efficient and economical. EPS meets the performance requirements as set out in the Standards Association of Australia's AS 1366, Part 3 - 1992 (table 1)

PROPERTIES OF EXPANDED KOOLFOAM
The service life of Koolfoam is virtually unlimited if the material is used knowledgeably. In this point Koolfoam does not differ from most other building materials, but because its properties are less well known, there is a greater risk of it being mishandled. This bulletin discusses those properties of cellular material made from Koolfoam that are relevant to its use in building.
