Product Handling


Please follow the application guidelines issued by Dow. STYROFOAM™ panels melt at high temperatures. The recommended maximum temperature for continuous use is 75 °C. Please note that on hot summer days STYROFOAM™ panels should not be covered with dark coatings/coverings (sealants, fleece, matting), otherwise the insulation panels may become distorted. When bonding STYROFOAM™ panels with colored outer layers, temperature changes on the surface of the outer layers should be monitored. Avoid using dark outer layers.

Should STYROFOAM™ panels come into contact with materials, which contain volatile substances, solvent damage could occur. When choosing an adhesive, please follow the manufacturer’s instructions regarding usability for bonding polystyrene foam.

To prevent weathering of the surface during long periods of storage outdoors, panels should be protected from direct sunlight. Light colored plastic film is ideal for this. Dark colored or clear film should be avoided as this could encourage a build-up of heat.

Panels should be stored on a clean, level surface, away from flammable materials. Panels contain a flame-retardant additive, which should prevent accidental ignition by a small naked flame. However, panels are flammable and could ignite if they are not professionally processed or used incorrectly. Therefore, during shipping and storage as well as during and after installation, these materials should not come into contact with naked flames or other ignition sources/flammable substances.

All flammability classifications are based on laboratory tests and do not necessarily reflect the behavior of the material in the final application under actual fire conditions. After processing, panels should be suitably protected against direct exposure to fire in accordance with national building regulations. Fire protection requirements are outlined in national building regulations, which must be complied with.
