In the demanding conditions of today’s building and engineering projects STYROFOAM™ blue extruded polystyrene boards can deliver the thermal performance and strength you require - for the lifetime of the structure. As a world-class producer of thermal insulation products, Dow can provide all the help, advice and information you need to achieve the solutions you’re looking for. Dow has developed STYROFOAM Solutions, for using STYROFOAM to maximum effect in a wide selection of typical application areas.

››› 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, which retains 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, mould or fungal growth is therefore minimised. They are clean, odourless and free from irritating dust.

Sandwich panels have found wide application as mainstream architectural components, but also in more specialised fields from clean-room linings to caravan and portable building construction; from UPVC window infill panels to conference room whiteboards; from lightweight doors to conservatory structures.

Laminated with materials such as aluminium, steel, wood and certain plastics, Styrofoam produces sandwich panels with excellent physical attributes including flexural strength, high rigidity, column strength and impact resistance. Its naturally high strength-to-weight ratio results in light but durable panels and its chemical stability and moisture resistance give it a high resistance to weathering and heat cycling. Styrofoam can be precisely hot-wire cut to customer specification, a process which is dust-free, leaving a surface in perfect condition for subsequent bonding.

An extensive test program has been carried out, including small-scale dynamic fatigue testing, panel surface temperature measurements, testing the effects of solar exposure and large-scale panel testing to failure. Results have confirmed that Styrofoam is a core material ideally suited to the temperatures of today's sandwich panel industry.
