Results on Thermal Annealing of Graphite Enhanced Polystyrene Insulations

From the beginning, the buildings have been tasked with protecting man from the external environmental impacts. Technological development has brought with its buildings and building structures development. Nowadays, the expectation is that in the interior of buildings it is for man to ensure a comfortable environment at all times of the year. External environmental conditions offsetting specifically requires a large amount of energy. In the European Union for buildings, its energy consumption accounts for about 20-40% of total energy consumption. The amount of energy required can be reduced, for which is a good solution. With thermal insulation, we reduce both in the building the transfer of the amount of heat generated or introduced into the building to the external environment, or it also minimizes the amount of heat that enters by radiation. Polystyrene insulations are ordinary, and their thermal properties are well known. However, the most promising type is the graphite enhanced one with relatively little information. These graphite doped material products have much better thermal insulation properties than the conventional (white) ones. In this paper, measurements of thermal conductivity after thermal annealing will be presented. Moreover, we will show some structural changes, and differential scanning calorimetry measurement results, too.
