The aim of this paper is to study the thermal and acoustical insulation of four different buildings’ envelopes mostly used for residential buildings in Tetouan city. The thermal and the acoustical models were investigated during summer season, while a linear nonmonochromatic source of sound has been placed 1m away from the exterior side of each wall and it is emitted a low-frequency sound waves with a velocity of 200 m/s. The study shows that the double layers of hollow clay brick wall with a medium of air gap presents a good thermal resistance and soundproofing compared to the other walls under study, due to the insulation by air gap with a thickness of 0.06m. Moreover, the homogenous and thick walls are simultaneously performant as thermal and sound insulators.
