Excellent thermal insulation

Rising energy costs have made the public increasingly aware of and interested in energy efficient solutions in all areas of life. Opting for STYROFOAM™ and XENERGY™ as the core layer material for composite panels means opting for long-lasting effective thermal insulation, because it is impervious to moisture and has low thermal conductivity.

High water and vapour resistance

The moisture resistance of the core layer material can have a significant impact on the durability of the external structure of a composite panel, and can affect long term insulation performance. Moisture in core insulation materials has a negative effect on thermal insulation properties and can contribute to the development of mold.

Additionally, trapped moisture conducts heat 25 times better than air. In structures where gas-tight outer layers are not used, moisture can penetrate the core layer material by diffusion and condense. Damage to outer layers can also lead to moisture accumulating in insulation material. As well as good thermal performance, STYROFOAM™ and XENERGY™  also provide high water resistance, ensuring a consistently good thermal performance.
High mechanical performance

The performance and durability of a composite panel depend upon the proper harmonization of its constituent parts and the manufacturing process itself. From decades of experience in a whole range of applications, Dow has built up a vast store of know-how – both on production technologies and on the various components of the composite panel. STYROFOAM™ and XENERGY™ are ideally suited as a core material because:
  • its high compressive strength prevents the facings from buckling
  • it increases the composite panel’s resistance
  • to deflection
  • its shear strength provides a very high shear modulus
Excellent bonding properties

The choice of adhesive and bonding technique is governed by the strength requirements of the panels to be produced, and their particular application. A wide range of sheet materials can be used as facings for lamination to STYROFOAM™ and XENERGY™  core material including:
  • Wood-based sheets
  • Aluminum
  • Steel
  • PVC
  • GRP
  • Gypsum plasterboard
  • Gypsum cellulose fiber
  • Glass
Tailored to fit - easy to use

STYROFOAM™ and XENERGY™ extruded polystyrene foam panels are produced with a flat, dust-free surface and narrow tolerances.
Hot-wire foam cutting equipment makes it  possible to cut core layers of as little as 5 mm thick from STYROFOAM™ blocks.

Customer focus

Based on decades of experience in the use of STYROFOAM™ as a core material and on modern simulation programs, Dow’s experts regularly assist customers with the structural design and development of their products.
Long-term proven performance

Dow undertakes rigorous quality management during and after the production of STYROFOAM™ and XENERGY™  in order to manufacture of consistently high quality products. Every two to three hours a sample of the production run is taken to check key properties such as dimensions, density, thermal conductivity and compressive strength, etc. Data are captured in a database accessible to all plants. Selective product analyses are also conducted in the central Research and Development Department’s laboratory in Rheinmünster.
