A firetest on a straw bale wall with 6 cm limeplaster (graefix 73 pajalith). The test was made 2012 on iBMB Braunschweig.
The firetest for the 6 cm plaster was successful so the plaster (the straw bale-modules with plaster) may be installed on 5 story straw bale buildings – as in this example on the “Norddeutsches Zentrum für Nachhaltiges Bauen” (North German Centre for Sustainable Construction (NZNB))!
