INFLUENCE OF MATERIALS ON THE THERMIC ISOLATION OF A CONSTRUCTION SITE

Abstract

The object of the heat transfer research is obtaining a coherent quality balance for a building’s structure because any wall assembly must have a convenient, suitable insulation and establishing a conventional energy consumption value for a building equal to the total of different forms of consumption (heating, warm water, ventilation, climatization, auxiliary equipments, lighting, etc.). We did theoretical and experimental researches in many "sandwich” structures which can be largely used in prefabricated wood housing. The aim of the research is the possibility to compound some indigenous thermal insulator material (i.e. mineral wool, polystyrene, PAL) in order to obtain a "sandwich” structure with thermo-physical properties which matches the author preoccupations. The results obtained by maintaining the layer of polystiren consistent in the middle and modifying the layer of mineral wool but keeping the 16 mm PAL sheets are comparable to the ones obtained by maintaining the layer of mineral wood consistent in the middle and modifying the layer of polystiren. The results are graphically represented and the thermal coefficients of the amples are taken into account.
