Please view our suite of products below and inquire with us if we may be able to develop something to suit your needs.


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.
