Abstract

     This work describes a composite material based on granular cork bound with gypsum. It is a complex medium with a double porosity: the first is that of granular cork having an irregular forms and the other relative to gypsum. An experimental study was conducted on this material in order to characterize its thermal properties. Its thermal properties were compared with those of gypsum for motivate the proposal that cork-gypsum material will be used as false ceiling. Finally, the energy performances of this material were compared with those of gypsum without cork. The findings of experiments indicate that cork-gypsum materiel is better than gypsum without cork in term of thermal insulation, energy storage capacity and slowness of heat transmission; the material is also significantly lighter than gypsum without cork. Its utilization as false ceiling will allow deducing a very interesting energy gain and will be then a contribution to improve energy efficiency in buildings.
