[en] This paper proposes the development of a new type material with thermal and acoustic function, to be used by the construction industry. This material, formed by pressing, is composed of two layers: an inner layer with high porosity and an insulating function, and an outer layer, characterized by a low porosity, which has mechanical and aesthetic function. To develop this material was necessary to characterize different raw clay materials. Five different samples were collected from the coast of Paraiba which were characterized with the following tests: chemical analysis, particle size distributions, plasticity index and thermal analysis. In addition, the density, apparent porosity and shrinkage of the fired samples have been determined. The results show that the samples have different characteristics and suggests the sample 4 to form the outer material and the sample 1, due to high porosity and high temperature sintering to be used inside the material.
