Wood-based insulation

Researchers at the Brunswick, Germany–based Fraunhofer Institute for Wood Research have developed a new wood-based insulation material that consists of foamed wood particles. Aiming to create a more environmentally effective substitute for conventional petroleum-derived insulating products, the researchers established a process to transform wood into aerated panels. They grind wood into a fine pulp and add gas to expand the particle soup into a bubbly foam. Next, the scientists allow the foam to harden into a lightweight base material, which they can process further into rigid panels or flexible mats. According to the team, wood foam exhibits performance and longevity comparable to traditional polymer foam insulation.
