Resumen

The manufacture of construction materials with conventional inputs generates negative impacts on the environment and contributes significantly to energy consumption. Therefore, facing this problem requires new alternatives. This research proposes a thermo-insulating panel made of Stipa Ichu fibers, cellulose, and gypsum for its application in a High Andean house. In order to evaluate the panel, its resistance to compression, bending, fire, fungus and acoustic insulation was characterized. Subsequently, the thermal behavior in the interior lining of a house was evaluated. The results reveal a compressive strength of 28.30 kg/cm2, flexural strength of 18.35 kg/cm2. The 12.50 mm thick panel showed a fire resistance of more than 60 minutes, 30% absorption and 70% noise reflectance, as well as adequate durability against fungi. With respect to thermal behavior, this thermo-insulating panel increases the interior temperature by 2.30°C with respect to a typical house, which makes its use feasible. © Derechos de autor: Leyda Cinthia Aza-Medina, Hugo Anselmo Ccama-Condori, Diana Karen Pari-Quispe y Abrahan Henry Torres-Benavides y Juan Anthony Humalla-Quispe, 2025.
