In addition to their classic application in building structures, POLYFOAM™ XPS thermal insulation can be used in numerous other areas, structures, for a wide variety of purposes.
In such cases the physical properties of the closed-cell polystyrene foam resulting from its unique material structure are especially important.
- excellent mechanical strength and high durability
- high, long-lasting thermal insulation performance
- lightweight and easy to handle
- easy to cut with simple tools
- not sensitive to moisture
- frost resistant
POLYFOAM XPS closed-cell polystyrene foam thermal insulation is suitable for the short and long-term thermal insulation and frost protection of
- sports facilities,
- unheated structures,
- thermal and structural insulation as a fabrication board for a wide variety of manufacturing processes and applications
- and for lightweight fill in the case of roads or engineering structures.
Sport surfaces must be protected against frost to maintain the quality of the playing surface and to prevent the risk of unevenness and reduced bearing capacity during the thaw. The most effective way to do this is to use thermal insulation beneath the surface, rather than excavate and replace large quantities of substrate. Insulated tracks enable the season to be significantly extended. The spring sun will quickly thaw and dry out the surface layer so the season can start early. In the autumn a carefully built and well drained, insulated sports surface will be able to offer good conditions long after the frost has come. The long season is beneficial for users and maximises the return on investment.
INSULATION FOR UNIFORM UNHEATED STRUCTURES
Insulation for uniform unheated structures The foundations, substructure and floors of unheated structures can be at risk of frost heave if the base layer is not kept frost free. The most effective way of reducing the risk of damage from frost heave is to insulate the ground beneath the structure and adjacent to it.
The insulation must be thick enough to prevent the temperature in the sub-soil liable to freezing dropping below 0ºC. It must also prevent the layer between the insulation and the subsoil freezing. In the build-up structures is important a min. 0.1m thick drainage layer beneath the insulation.
Long term water supply and waste pipes solution Pipework systems must be protected against frost to main- tain trouble-free performance.
The water in pipes must not freeze and the pipelines must not be damaged or fractured by frost action. Heavy demands are placed on insulation material for water supply and sewage installations: it must maintain its insula- ting capability for the service life of the pipe – between 50 and 100 years – and must withstand loads from works traffic.
The use of POLYFOAM XPS will achieve considerable savings for the insulation of water supply and sewage systems
THERMAL AND STRUCTURAL INSULATION
The lightweight POLYFOAM Laminating Board is suitable for thermal and structural insulation as a fabrication board for a wide variety of manufacturing processes and applications. The baords are highly resistant to compression and can withstand both occasional and long term static loads. Load bearing construction elements should be designed to adequately support the combination of imposed and dead loads without creating excessive deflection. POLYFOAM Laminating Board is resistant to moisture absorption and can be installed in standing water, high humidity factory conditions or up against wet surfaces with negligible impact on the performance of the product.
PREPARATION OF LIGHTWEIGHT FILL IN THE CASE OF ROADS OR ENGINEERING STRUCTURES
The replacement of heavy, dense embankment materials with low-density, light materials in the embankments has become increasingly common in engineering practice. The most commonly used replacement material is polystyrene foam with its closed-cell structure. The selection of the appropriate POLYFOAM XPS polystyrene foam product varies depending on the static and dynamic circumstances of the given application. As this method spreads, the requirements for light embankment materials are gradually becoming stricter. Generally, it can be said that the material needed has both permanently high compressive strength and resistance to creeping with moisture resistance.
