The OrganoPor research project was successfully completed on July 31, 2019. The objective of the project was the first-time realization of composite thermal insulation systems (ETICS) and impact sound insulation panels made of porous, self-supporting and flame-retardant hybrid materials based on renewable natural residues.
In the OrganoPor project, novel, sustainable facade insulation materials were developed from residual and waste materials from agriculture and forestry, which are available in sheet form compared with similar materials and exhibit reduced fire behavior. In the course of the work carried out, a bio-based solution was developed in comparison to composite thermal insulation systems based on polystyrene foam. Porous, self-supporting and flame-retardant hybrid materials were produced from renewable residual and waste materials such as cork or corncob meal, water-based resins based on lignin and mineral fillers (flame retardants). The porous particles were coated with a biobased duromer including mineral flame retardant and pressed into sheets. In the event of fire, this hybrid material behaves analogously to the polystyrene foam-based hybrid material: The non-combustible duromer framework protects the foamed biomaterial embedded in it from fire.
