Jackodur® Atlas – made of extruded polystyrene foam (XPS) – is an intelligent, efficient thermal insulation and formwork system for floor slabs. The innovation part is the new, economical interlocking system, which provides thermal bridge-free insulation in all types of buildings.

Foundation System

Jackodur® Atlas represents a cutting-edge solution crafted from XPS (extruded polystyrene) foam, setting a new standard for intelligent and efficient thermal insulation and formwork systems, particularly for foundation floor slabs. This innovative system incorporates an interlocking design that skilfully eliminates thermal bridges, ensuring superior thermal performance.

One of its distinguishing features is its robust compressive strength properties, providing stability and reliability to your construction projects. Jackodur® Atlas is supplied pre-cut to size, guaranteeing rapid and hassle-free construction processes. This not only enhances efficiency but also contributes to a smoother construction experience, making it a favoured choice among builders and developers.

Key Benefits

  • Installation can be done by the general contractor
  • Faster, less complicated ground preparation
  • Simple, clear instructions
  • Flat slab design creating lower ground pressure
  • Complete over site slab offers greater internal design flexibility
  • Eliminates thermal bridging
  • Thermal mass of slab within the building envelope
  • Installation not restricted by weather conditions

 

XPS for below ground applications

When developing an insulation system for concrete foundation rafts BEWI decided to use their expertise in extruded polystyrene (XPS) rather than conventional expanded polystyrene (EPS). XPS is produced by melting beads of polystyrene in an extruder and then injecting carbon dioxide into the molten material. This creates a closed cell structure with no voids in the material and a uniform skin that repels water. XPS from BEWI only absorbs less than 1% of moisture even when submerged in water at high pressure or in freeze thaw conditions. EPS is produced by expanding beads of polystyrene at high temperature in moulds. This can leave microscopic voids between the individual beads. When submerged in water for long periods of time EPS can absorb varying proportions of water. As very experienced manufacturers of EPS, BEWI can produce EPS that absorbs less than 5% moisture when subjected to water under pressure; but other qualities of EPS can take in up to 10% particularly when subjected to repeat freeze thaw conditions.

Certified

The Jackodur® Atlas XPS-material is covered by a European Technical Accreditation (ETA) for use as insulation under a concrete slab. We also have a thorough Environmental Product Declaration (EPD) that analyses the long-term impact on the environment due to the manufacture, transport, utilisation and recyclability of the products. Jackodur® Atlas is also certified by the German Passive House Institute.
