Sheets and Blocks
Using our EPS block moulds, we produce very large polystyrene blocks which can then be cut to the desired shape and size, either with our wire cutter, which produces blocks and sheets (pictured) or with our CNC-router which can produce more complex shapes. Polystyrene blocks can be produced in a variety of densities in order to meet your needs.

Shape Moulding
With the creation of a specific mould, polystyrene can be used to provide insulation or a protective layer, with specific applications to the automotive, logistics, produce and refrigeration industries. We can develop moulds to suit any purpose, please contact us regarding mould designs and costings for your business needs.

Ceilings and Cornices
Cumulus delivers several solutions which employ polystyrene in order to provide insulation for ceilings, from laminated ceiling boards to our own Ecoboard. These have a variety of applications due to their insulation, damp proof and fire-resistant properties. We also have a variety of polystyrene cornices available to add an extra touch of class to your project.

We are primarily engaged in the manufacturing and cutting of Expandable Polystyrene, the cutting of metal sheets to size and the lamination or sandwidging of these components to produce the insulated modular panel. We supply these panels or polystyrene sheets separately if demanded, but also add further value to produce our own various range of constructions, including mobile office and housing units, cold and freezer rooms, containers, guardhouses, ablutions or most any construction where specs are provided. We also have the equipment to bend an IBR profile from our metal sheets which we sell as roof sheets or roof panels. One of our latest products, the Green Fodder Rooms, are aimed at the agricultural community and enables them to effectively grow supplementary fodder for their livestock.
