About Us

A European building technology, brought to America.

SYSTEM 3E USA was set up to bring the perlite wall system to the United States: first the supply, then the American factories, with a team that has built companies and factories before.

Supply

Manufactured in a purpose-built, automated plant.

SYSTEM 3E produces every element in its own 87,000 sq ft facility in Radomsko, central Poland, using robotics and automation. Production consumes minimal energy and water and emits no fumes.

The farthest project delivered from the plant so far is in Andalusia, Spain, over 1,850 miles, and remained profitable. SYSTEM 3E USA is building the North American channel now: talk to us about project supply, distribution territories, and pilot builds.

Sustainability and ESG

Built to stand up to ESG reporting, not just to talk about it.

More and more of our customers have to document how a building was made: what it emitted, what it wasted, and what happens to it at end of life. SYSTEM 3E is designed so those answers are simple, and so that the numbers behind them come from tests and production data rather than from marketing.

Environmental

One mineral raw material, 99% natural perlite. Up to 99% less construction waste on site, 67% lower water use and 54% lower CO2 in production compared with traditional masonry construction. Elements can be taken apart and reused, and the raw material is 100% recyclable.

Social

Lighter elements, about 70 lb each, and no wet trades make the work safer and open it to crews without specialist masonry training. No mineral wool, no polystyrene and no toxic chemistry, so the air on site and inside the finished home stays clean.

Governance

The product is CE marked to the harmonized standard EN 771‑3 and manufactured under a documented factory production control system, with declared performance values that any engineer can check. We publish test reports and we do not claim approvals we do not hold.

What we can document

  • Declaration of Performance and CE marking to EN 771‑3.
  • Fire, thermal, acoustic, structural and moisture test reports from accredited European laboratories.
  • Production and material data behind our waste, water and CO2 figures.
  • Support for green building documentation such as LEED, BREEAM and EU taxonomy reporting, together with your consultant.

Where we are honest

Our ESG figures come from European production and European testing, because that is where the plant is today. As U.S. manufacturing starts, the same data will be produced here. If your project needs a specific declaration, an EPD or a U.S. code evaluation report, ask us and we will tell you exactly what exists today and what is still in progress.
