Resumen

Entre las muchas funciones que debe tener un material de construcción, destacan sus funciones de aislamiento. Este tipo de materiales actúa disminuyendo la conducción de calor/sonido hacia el medio ambiente. En este contexto, los bio-aislamientos han recibido una atención creciente debido a su desempeño y al uso de materiales de aislamiento sostenibles/naturales. Este estudio se realizó para evaluar el rendimiento térmico y acústico de placas de base biológica hechos de biomasa de Spirulina, poli-β-hidroxibutirato bacteriano (PHB) y lana de vidrio. Las placas se fabricaron con compresión calentada en diferentes proporciones: 33.33% de lana de vidrio, 33.33% de PHB y 33.33% de biomasa de Spirulina (Placa A); 20% lana de vidrio, 40% PHB y 40% Spirulina (Placa B); 40% lana de vidrio, 40% PHB y 20% Spirulina (Placa C); y 40% de lana de vidrio, 20% de PHB y 40% de Spirulina (Placa D). Las placas A y B mostraron una conductividad térmica más baja (0.09 W m-1 K-1) en comparación con los materiales aislantes tradicionales, como yeso puro (0.44 W m-1 K-1) y ladrillo aislante de caolín (0.08–0.19 W m-1 K-1). La placa D mostró el coeficiente de absorción acústica más alto de ~ 1600 Hz en comparación con otros aisladores de base biológica a la misma frecuencia, como fibra no tejida a base de polipropileno y fibra de hoja de té con el mismo grosor. Para el coeficiente de reducción de ruido, el tablero B mostró mejores resultados que el concreto. Por lo tanto, las placas A y B son adecuadas como aislantes térmicos, mientras que las placas B y D son adecuadas como aislantes acústicos. Para la aplicación simultánea como aislante térmico y acústico, la placa B es la mejor opción entre todas las placas.
