Dow Building Solutions Introducing STYROFOAM Solutions: performance, product overview and references

About STYROFOAM In the demanding conditions of today’s building and engineering projects STYROFOAM™ blue extruded foamed polystyrene boards can deliver the thermal performance and strength you require - for the lifetime of the structure. 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...

Meeting environmental standards STYROFOAM™ is manufactured under the BS EN ISO 9001: 2008 Quality Management System (BSI certificate Q05968). Dow also operates an Environmental Management System which has accomplished ISO 14001:2004 (BSI Certificate EMS 547690). Concern about ozone depletion in the stratosphere has led to international agreements to phase out the use of ozone depleting chemicals. All STYROFOAM™ products are hydrochlorofluorocarbon (HCFC) free and comply with the requirements of EC Regulation No 2037/2000 (1 October 2000) on substances which deplete the ozone layer. STYROFOAM™...

Surface characteristics Dow STYROFOAM™ boards are blue. All boards have a smooth homogeneous skin on both sides with the exception of ROOFMATE™ LG-A and PERIMATE™ DI-A. STYROFOAM™ has a low susceptibility to rot, and mould or fungal growth is therefore minimised. Chemical Structural STYROFOAM™ boards are available in a range of compressive strengths to suit different load bearing requirements. Fire Information on aspects of fire performance of extruded polystyrene in building applications is given in BS 6203: 2003, ‘Guide to fire characteristics and fire performance of expanded polystyrene materials...

Product overview FLOORMATE™-A FLOORMATE™-A is the STYROFOAM™ Solution for insulating floors, and is currently available in three grades, FLOORMATE™ 300-A, 500-A and 700-A. FLOORMATE™-A insulation is available in a range of compressive strengths to match the loading requirements of individual projects. FLOORMATE™-A insulation can be installed under or over the slab in ground bearing concrete floors and is suitable for use with suspended beam and block and timber floors. ROOFMATE™ SL-A and ROOFMATE™ LG-A ROOFMATE™ SL-A is the STYROFOAM™ Solution for insulating inverted roofs. The boards are highly...

Recommendations STYROFOAM™ products include FLOORMATE™, ROOFMATE™ and PERIMATE™. STYROFOAM™ products contain a flame retardant additive to inhibit accidental ignition from a small fire source. STYROFOAM™ is, however, combustible and if exposed to an intensive fire may burn rapidly. During shipment, storage, installation and use STYROFOAM™ products should not be exposed to flames or other ignition sources. Fire classification is based on small scale tests, which may not reflect the reaction of the products in its end use state under actual fire conditions. STYROFOAM™ products should, when installed,...
