The aim of the project is to develop a technology to receive, so far unknown material for thermal and acoustic insulation, especially for the construction industry. A hybrid insulation material (HTM) will be produced during the thermal forming of pellets of expanded EPS with an incorporating interphase. Recycled cellulose microfibers or ligno-cellulose microfibers from biomass, flame retardants, fungicides and a binder will be used as the interphase. The binder will facilitate the deposition of the interphase on EPS granules and the integration of all components of the composite. HMT obtained by the proposed solution has mechanical properties and thermal resistance of polystyrene (k λ<0,040W/mK) and diffusion resistance characteristic for vapor permeable materials. Diffusion resistance of HTM will be regulated by the amount and composition of interphase. The developed insulation material will be economical for ecological reasons and will reduce the cost of insulation.
