In Europe there are a few companies that are offering clay based wall boards. I am curious if there are similar products offered in Canada and US, does anybody know? I had asked the company claytec (https://www.claytec.de/en/products/clay-drybuilding#) if they are distributing in North America a couple of years ago. That time they did not, maybe they do now. Here is a dataset from the LCI Okobaudat database: Clay panel (thickness 0.02 m); 14 kg/m2. This is the UK Greenspec description https://www.greenspec.co.uk/green-products/plasterboard-and-clayboard/details/claytec-clay-board/
