Polyurethane stands out in the field of civil construction as a material for such use, which can generate energy savings and greater comfort in the construction, however polyurethane has a high flammability, demonstrating the need for flame retardant additives. This study describes the effects of PU composites with the addition of polyvinyl chloride residues from conduit and aluminum anodizing sludge for use as a thermal and acoustic insulator with flame resistance properties and energy efficiency analysis with a virtual model using PU on the wall and cover. The composites were prepared containing 30%, 40% and 50% polyvinyl chloride residues from a fixed polyurethane mass, with and without 40% aluminum anodizing sludge. Observed by electron microscopy scanning after the vertical flammability test, the preservation of the internal material not being affected by the flames was evidenced. All composites showed resistance to horizontal and vertical flammability, reaching the most demanding classification according to UL-94. The addition of residue and its synergistic effect led to the extinguishing of flames, a decrease in heat release rate, reduction of mass loss during burning, thus with lower flue gas production. PU wall and roof elements generated for energy analysis simulation showed values suitable for use as thermal insulation. The energy simulation showed a reduction in energy consumption, an annual saving of 14.55%, a reduction in CO2 emission of 56.25% per year and values of energy use intensity within the recommended for lodgings and residences. Thus, it is suggested that the construction industry consider the use of materials with thermal and acoustic insulation properties with the incorporation of flame resistant residues, for better comfort and safety of buildings in a sustainable manner.
