RESUMO

The indoor comfort in buildings in researched by the architets as a basic criterion in the art of architecting. Volumetria studies, measuring of archs, space desing, studies of the air commuting as well as insolation are some of the asects which must be focused by the acting of projecting. by the time we developed the research on composite material to be used in the civil enginearing using gipsy and natural fibers, Maurítia vinifera Martius - buriti palm tree, we had as a main gool to obtoin a men material which could the used as a revestiment or elements of tapping, adding to it properties that conduct to a low thermic concdutivity. Based on the homogeous miscture of gipsy and natural fibers in specific proportion of composite were produced samples which were submitted to a " parallel heat wire Test " - part 2. ISO 8894 - 2, which consists in determining of the temperature with the materal samples through a seratch with wire resistor and a thermopair with 30º grade Celsius referential interconnented, respectivey, to an eletric source and a Signal Acquisition Board which determines the thermal conductvity of the materal through the propagation of heat isothermic wawes.The studies of mixing elements of definite proportion between mixed parts, the humidity level and the porosity of the samples have been of great importance to this research. The tests showed that the best performance was obtained by the mixture of and their percentagens of 0 % a 35 of materal fiber for the time between 640 a 1280 seconds
