Fossil mineral, pressed into a panel.
Diatomaceous earth is the fossilised remains of ancient marine diatoms — the same mineral that filters swimming pools and keeps insects out of grain stores. Bound with an inorganic matrix and pressed, it becomes cladding.
What is in it, and what is not.
The panel body is mineral. There is no wood flour, no cellulose fibre and no organic binder — the three ingredients that make conventional fibre cement swell, host mould and contribute fuel to a fire.
That single fact drives most of what follows. Nothing in the panel wants to burn, so fire performance is a property of the composition rather than a coating that can be scratched off. Nothing in it absorbs water, so freeze-thaw passes through it without spalling.
Composition figures are published here once third-party testing is complete. Nothing on this page is a certified claim yet.

It goes back in the ground.
Ground down, the panel is diatomaceous earth again. Mixed into potting soil it improves drainage, which is a genuinely unusual end-of-life story for a cladding product and one worth telling honestly rather than as a sustainability badge.
