Floor designs must be able to withstand the high floor loadings present in low temperature facilities.
The typical low temperature floor design has not changed for many years. The insulation is laid in multiple layers on a vapour retarder either over a sub-slab or directly over the soil. Reinforcement and slip sheets are positioned where necessary and the concrete for the wearing slab is poured directly onto the insulation.
After the wearing slab has cured, it must be able to support the live and dead loads imposed by any moving equipment, storage racks and stored materials. As design loads increase, the insulation plays a more important role in providing support for the wearing slab.
Thanks to an extremely high compressive strength-to-weight ratio, exceptional moisture resistance, low thermal conductivity and long-term performance of Dow Styrofoam HD-X extruded polystyrene insulation, makes it the ideal solution for cold store floor applications.
When used in cold store floor panels, Dow Styrofoam HD-X XPS supports heavy cargo loads and the dynamic loads of fork lift trucks. When used in walls it absorbs high dynamic loads, such as those caused by wind and vibration. When used in roof panels Dow Styrofoam HD-X will support high tensile loads from suspended items.
The homogeneous closed-cell structure ensures that Dow Styrofoam HD-X retains its performance even when in permanent contact with moisture. This exceptionally stable material will retain its initial insulation performance and physical integrity in exposed conditions over the very long term. It is this unusual property that made possible the inverted warm roof concept, pioneered by Dow.
