Material aislante en base a residuos textiles para el acondicionamiento térmico y acústico de espacios

Abstract

Abstract: The research evaluated the thermal and acoustic performance of insulating panels made from recycled textile fibers (RTF) and a vinyl acrylic resin (VAR) matrix, analyzing the influence of density on their protective efficiency. Three dosages with densities of 0.263, 0.229, and 0.186 g/cm3 were characterized and subjected to tests of thermal conductivity, thermal inertia, and sound reduction index. The results determined that the P80 sample represents the best insulation option, as it recorded lower thermal conductivity, the highest thermal differential, and superior acoustic reduction. In contrast, the P40 sample was identified as the lowest-performing variant, showing high acoustic transparency and poor thermal regulation capacity due to its high porosity. It is concluded that the compaction of the polymer matrix sealing material are critical factors for revaluing textile waste in the construction sector, ensuring stable thermal and acoustic comfort.
