−35%
build time.
Faster assembly, fewer surprises, so you move in sooner.
The elements slot together, without mortar or lifting equipment.
>50 dB

6 to 12 kg/m²
versus 221 kg/m².
That is the weight you handle, compared with a traditional concrete-block wall.
No scaffolding, no lifting equipment.
Process under official technical approval (CSTB), components certified by the Passive House Institute. EUROMAC2 manufactures, supplies and supports: you, or your builders, build.
From the idea to the keys:
how it works
5 steps to build with peace of mind.
1
You tell us
about your project
Free study and costing, with no obligation.
2
Our design office
prepares everything
Installation plans and structural calculations included.
3

You finally
move in
Enjoy your home in every season, with lower bills.
Two ways to build the same house.
Whether you have it built or build it yourself, you are not alone: we manufacture, we study, we support. You choose who builds.
I'm having it built
Keep your builders.
We support them.
We train your builders or your contractor: guides, installation plans, on-site assistance, design office. You don't have to become an expert.
Trained builders
One-day training, installation guides and on-site assistance.
Design and studies
Installation plans and structural calculations, carried out free of charge by our design office.
Faster build
Up to 35% of assembly time saved, without scaffolding or lifting equipment.
Verified performance
Official CSTB technical approval, components certified by the Passive House Institute.
I'm building it myself
Do it yourself.
You are not alone.
Assembly is within reach: elements of 6 to 12 kg per m², simple interlocking, no scaffolding or lifting equipment.
Easy to handle
From 6 to 12 kg per m² depending on thickness, versus around 221 kg/m² for a concrete-block wall.
Simple assembly
Slots together without mortar, like a building set.
Guides and training
One-day training, theory and practice, then step-by-step guides.
Support
Assistance at the key stages, starting with the first pour.
They live in them, they talk about them.
Houses built, lived in, and described by the people who live in them.
A 20,000 m² factory

What we are asked most often.
Straight answers, including on what is not up to us.
A single EUROMAC2 block fulfils four functions: load-bearing wall, internal insulation, external insulation and airtightness. Where a conventional build chains together trades and interventions, you have just one installation. Assembly is around 35% faster, with no scaffolding or lifting equipment.
Add to that the savings in use: up to 50% on the energy bill, every year and for the whole life of the house.
On material price per square metre alone, the concrete block remains cheaper. On the cost of a finished, insulated and airtight house, the comparison plays out differently. Costing your project is free: it is the only way to get an accurate answer.
That is the case for most builders who start with us, and it is not an obstacle. Training takes one day, installation plans and guides are provided, and our team assists at the start of the build.
The elements weigh 6 to 12 kg per m², where concrete blocks come in at around 221 kg. Assembly is done by hand, by interlocking, without lifting equipment. You remain free to choose your contractor or builder.
EUROMAC2 is a manufacturer, not a contractor. We manufacture, we study your project, we deliver to site and we assist during the build. The building warranty is carried by the company that does the work, exactly as with any other building material. You choose that company freely, and we train it if it wishes.
If you are planning to build yourself, one point to anticipate: without a contractor's warranty, obtaining a bank loan is more difficult. Best to discuss it with your bank early in the project.
EUROMAC2 has been manufacturing in France since 1976 and more than 28,000 projects have been completed. The process holds a CSTB technical approval, a European technical assessment (ETA, DIBt), CE marking and verified environmental declarations (FDES) filed in the INIES database.
All these documents are public. You will find them in our Resources area, and we will send them to you on request.
It is even one of the material's strengths. Expanded polystyrene is rot-proof: it does not go mouldy, does not rot and does not degrade over time. It receives no chemical treatment, unlike timber, which has to be treated against insects and fungi.
It also has no nutritional value: neither insects, termites nor rodents find anything to feed on.
For indoor air, the material holds the continuously renewed Zone Verte Excell label, which attests to its harmlessness: no pollutant detected in significant quantities. The polystyrene used is pFR grade, compliant with the REACH regulation. And unlike fibrous insulation, it releases no fibres into the air.
It is the opposite of what you might imagine. The concrete core poured at the heart of the wall keeps all its thermal mass: it stores the coolness of the night and releases it during the day. The external insulation blocks the heat before it reaches the concrete.
A house that stays cool during the day, without air conditioning.
This is precisely where EUROMAC2 stands out. The ties that connect the two faces of the block are made of steel. To our knowledge, we are the only manufacturer of insulating formwork blocks to make this choice: most systems on the market use plastic ties, which melt and open a path for fire between the two faces. Steel does not melt and does not spread flame.
The outer face, rendered with the renders specified for the process, is classified B-s1,d0: it does not spread flame, gives off very little smoke and produces no flaming droplets. The fire resistance of the complete wall, concrete included, depends on the lining chosen and is given in the technical approval, available in our Resources and on request.
