block moulded

We use block moulding to create large blocks of polystyrene which are then cut to the desired shape and size

We have a variety of tools such as hot wire cutters and CNC machines to be able to cut polystyrene to fit any application.

shape moulding

Shape Moulding encompasses building a mould to the desired shape and then expanding polystyrene within the mould to create the product.


Shape moulding allows for the creation of almost anything, from display products and seed trays to balls and other products.

laminated ceiling

Our ceiling panels use a sheet of polystyrene which is laminated with a sheet of plastic.

These ceiling panels are fire retardant and maintenance free, as well as non-toxic, making them suitable for food production enviromments.


Ecoboard is made of paper-wrapped cementitious fibres and is an alternative building technology, substituting gypsum or plaster board.

It can be used as a ceiling or drywall board and is advantageous due to its water resistance and insulative properties.

It is also fire resistant, with a 30-minute fire  rating per SANS 10177-Part 2 test protocols. At 9mm thickness, these boards are fire stop.


Our cornice provides an easy way to add a unique and decorative touch to your home.

We combine the use of polystyrene with other materials to create a more durable product.
