Contrary to popular belief, straw and wood buildings resist fire very well. The straw in our panels is compressed at a density of 110kg/m3, not leaving space for oxygen that would fuel the fire. Moreover, straw has a high content of silica, a natural fire retardant. When burning, both materials create a charcoal insulation layer on the surface that protects them from flames.
Combined with clay plaster, our panels are rated to withstand two hours of intense fire according to the REI 120 and REIef120 certifications, meeting strict fire safety requirements. In fact, after two hours of over 1000°C on one side, the other side showed a temperature increase of only 17.7
