    The present investigation develops the technological process for the manufacture of a thermal insulator obtained from the combination of gypsum with crushed waste of a material with glass fiber reinforced polymer (GFRP) for the manufacture of ceiling panels, the mechanical and thermal properties of flexure, hardness and thermal conductivity were evaluated of each volumetric configurations analyzed. From the tests, it was determined that the best mechanical and thermal behavior of the composite material was 50 percent gypsum and 50 percent GFRP with a thickness of 9.5 mm with a flexural strength of 10.93 MPa, surface hardness with a footprint of 13mm and thermal conductivity of 0.11 W / m K,, also the presence of GFRP residues reduces the weight of the ceiling by 60 percent as well as the manufacturing cost. In conclusion, composite material of gypsum with GFRP waste improved the mechanical properties compared to existing gypsum panels.
