About STYROFOAM
STYROFOAM™ has been manufactured by Dow since the 1940s. The process of extruding foamed polystyrene results in a material with uniformly small, closed cells, a smooth ‘skin’ and an unrivalled set of properties which make it the choice of specifiers in a wide range of demanding insulation applications:
- low thermal conductivity - minimising the board thickness needed to achieve a specific U-value, thus allowing the designer greater flexibility.
- high compressive strength - in load-bearing applications, the closed cell structure gives the foam great rigidity and makes it highly resistant to compression.
- low water absorption - STYROFOAM has natural resistance to rain, snow, frost and water vapour which makes it an exceptionally stable material, retaining its initial insulation performance and physical integrity in exposed conditions over the very long term. It was this unusual property that made possible the inverted warm roof concept, pioneered by Dow.
- workability- STYROFOAM is easily worked with normal hand tools.
- hygiene - STYROFOAM boards have low susceptibility to rot meaning mould or fungal growth is minimised. They are also clean, odourless and free from irritating dust.
STYROFOAM is available in a number of different formats designed to meet the performance requirements of specific applications.
