General Building Inspection Test Certificate (AbP): General Building Inspection Test Certificate, Fire Resistance Class F30-B (straw bale wall plastered on both sides with clay or lime) P-3048/817/08-MPA-BS, valid until 24 January 2029: Download

European Certificates (full scale fire test) made by OSBN (Poland) for REI 90 (not connected to a special material-brand, so open to everybody in Europe), but with 40cm thick straw bale walls (below the whole report): In practice we would need to add 4cm of e.g. straw boards or wood fibre boards to the 36cm straw bales in a double-post timber-frame-construction.
