Polystyrene foam boards (PS) are the most common insulation material, used in more than 90% of all thermal insulation composite systems (TICS), states an article on Bioplasticsmagazine.com. There have been hardly any bio-based alternatives, as they are associated with manageability and price issues. The Fraunhofer LBF’s project developed a competitive, bio-based hybrid material for PS boards which are also price-competitive — a pioneering achievement.
