Litterally translated, polystyrene is ‘ polymerised styrene”. The expandable form (known as EPS) is initially produced as small beads containinga blowing agent. The beads expand when treated with steam, forming a lightweight “prefoam” of the required density.
These prefoamed beads are processed in a mould to form large blocks that are then cut into sheets or other shapes. Alternatively, for high volume products, the beads are moulded into their final product form in individual moulds.
Thermal insulation of buildings is becoming increasinly relevant as energy costs rise and climate change is reality. One area that acts as a thermal heat soak is the under floor area of any building drawing heat generated inside buildings into the ground. The thermal under floor system acts as a easy to install under floor insulation system as well as having a number of other functions and benefits.
Ground floor insulation – EPS is used in a multipality of applicationsfor its thermal insulating properties. The EPS sheeting acts as a thermal barrier to prevent under floor cold penetrating rooms and keeping heat generated in houses from being dissipated into the ground.
Optimisation of underfloor heating systems.
If under floor heating is installed the EPS thermal under floor system should be obligatory. EPS will ensure that heat generated is not absorbed by the ground and is forced upwards into the house itself.
Long Life – EPS is rot and rodent proof and dimensionally stable and thus will retain its thermal insulating and moisture barrier effectiveness for the life of the building.
