Moulded parts, right the first time
With moulded foam the mould decides the part, so a wrong mould is a scrapped run, not a quick fix. We mould expanded polystyrene (EPS) to your shape, use expanded polypropylene (EPP) where a part is reused or takes repeated impact, and cut the moulds in our own Pretoria toolroom.

Built for the people who sign off the part
Engineers and specifiers
You are signing off a part that has to behave the same on the thousandth unit as on the first. We mould to your drawing, hold the spec across the whole run, and record what we ran to.
Cold chain and facility teams
You keep product cold from the store to the delivery, and a box that fails in transit is stock you write off. We mould thermal packaging that holds temperature and takes the handling of a real supply chain.
Discuss cold-chain requirement
Pharma and regulated packaging
You answer for packaging that has to perform the same way on every batch, and stand up when someone checks. We mould to a held specification and keep it consistent, run after run.
Procurement
You have been caught before by the cheapest quote that failed in the field. We keep the tooling and the moulding under one roof, which is why your second order matches your first.
Growers and agriculture
You need seed trays and cold chain packaging that take rough handling and come back for the next season. We mould EPS that keeps its shape through the knocks.
Architects and designers
You are specifying cornices and skirtings for a space, and you need profiles, dimensions and data you can drop straight into a drawing. We give you the specification detail and the design support to match it.
The tool makes the part
With moulded foam, almost everything about the part is decided before the first one comes off the machine. The mould sets the size, the finish and the strength.
Get the mould wrong and you do not trim it to fit. You remake it, and the run you have already paid for is scrap.
So the real question is not who can mould. It is who controls the tool. When the toolmaker sits in another company, every change is a delay and a purchase order. When the toolmaker sits next to the machine, a change is a conversation.
What we make
We mould and cut EPS for packaging, agriculture, cold chain, industry and the building trade, with selected EPP where a part has to be reused. Here is what the division makes.
What is Isowall Moulding?
Isowall Moulding is the moulding division of Isowall Group, a South African manufacturer with over 53 years behind it. We mould expanded polystyrene (EPS) to shape, process blocks and sheets, make cornices and skirtings, and cut our own moulds in our toolroom at our 45,000m² Pretoria facility, for packaging, agriculture, cold chain, industry and building.
Shape moulded EPS
Shape moulded EPS
Parts moulded to the shape your job needs, not a shape off a shelf. Our shape-moulding line is Isolite.
- Moulded from your drawing, your sample, or a problem you describe
- EPS for protection, insulation and low weight
- Selected EPP where the part is reused or takes repeated impact
- The same dimensions on the first part and the last
- Seed trays, protective packaging and industrial mouldings
Core EPS: blocks, sheets and cutting
Core EPS: blocks, sheets and cutting
Large blocks and sheets, cut to whatever profile the job calls for.
- Blocks and sheets made to order
- CNC cutting to your profile
- Insulation for floors, roofs and cavities
- Decking blocks and lightweight building blocks
- A material you can recycle
Skirtings and Isowood

We also make EPS cups and tubs for food service, branded Hebcooler. We keep this a contained line, mainly for trade and B2B supply.
Why doing it ourselves matters to you
01
We cut our own moulds, so the first run is right and the change you ask for is not stuck in someone else’s queue.
02
We mould at two plants, in Pretoria and in Kempton Park, so a bigger order does not put you in a longer line.
03
The checks we run for our most demanding industrial work run on your job too, whatever its size.
04
In 2007 we commissioned the first computer-controlled EPS cutting line in Africa, at our Pretoria factory.

Frequently asked questions
Who is Isowall Moulding?
Isowall Moulding is the moulding division of Isowall Group, a South African manufacturer, and we mould expanded polystyrene (EPS) to shape, process blocks and sheets, and make cornices and skirtings. We work from two plants, in Pretoria and in Kempton Park, Johannesburg, and we cut our own moulds in our own toolroom on the Pretoria site.
What is the difference between EPS and EPP?
Expanded polystyrene (EPS) is the lighter, lower-cost choice for protection, insulation and cold chain packaging, while expanded polypropylene (EPP) is tougher and can be used again and again. EPS is our main moulding material, and we use EPP where a part needs to be reused or take repeated impact, so we will tell you which one suits your part.
Why does it matter that you build your own moulds?
Because with moulded foam the mould decides the part, so building and holding the mould ourselves lets us get the first run right and fix tolerances without an outside toolmaker. It also means a design change is a walk across the floor, not a purchase order to another company and a wait.
Can you mould to our own specification?
Yes. We mould from your drawing, your sample, or a problem you describe, and we hold that specification across the whole run, whatever the volume. Send us the drawing or the sample and our team will tell you what is workable and what it will cost.
What do you make moulded foam for?
We mould for protective and thermal packaging, cold chain, pharmaceutical and regulated packaging, farming including seed trays, general industry, and lightweight building and insulation work. We also make decorative cornices and skirting profiles for the building trade, and a contained range of EPS cups and tubs for food service.
Where are you, and who do you supply?
We manufacture in South Africa, moulding at our Pretoria plant and a second plant in Kempton Park, Johannesburg, with our toolroom on the Pretoria site. We supply engineers and specifiers, cold chain and packaging buyers, procurement teams, growers and the building trade, architects included, across the country.
Manufacturing depth, not a foam middleman
- Over 53 years of manufacturing in South Africa.
- A 45,000m² plant in Pretoria, a second plant in Kempton Park, and a team of over 500.
- Our own toolroom, so the tooling, the moulding and the quality all answer to one company.
- Certified to ISO 9001:2015 and ISO 14001:2015 across the group, with FSSC 22000 food safety certification at the Pretoria plant.
