Bio-bonded straw and wood particleboards pass small-flame fire test in lab
Source: Fire, "Reaction-to-Fire Performance of Steam-Exploded and Suberinic Acids-Bonded Particleboards for Building Façade Applications", published 11 November 2026.
What the source says
Laboratory high-density particleboards from wheat straw, grey alder and softwood, made binder-less by steam explosion or bonded with suberinic acids, were fire-tested by cone calorimetry at 50 kW/m2 and by ISO 11925-2. All met the single-flame criteria; wheat straw boards had the lowest heat-release intensity.
Allbase view
Lab-made boards only, tested with a cone calorimeter and a single-flame ignition test, not a full façade fire test. Bio-based binders for façade panels are a long way from specification; nothing to act on yet.
