Abstract

Formative research was carried out to analyze the effectiveness of fiberglass coatings on prefabricated modules. The purpose of the research is to evaluate its thermal and acoustic insulation capabilities. The work covers the construction of two boxes with different materials: one with prefabricated modules, another with traditional mortar and one with fiberglass coating. The procedures used encompass the hot chamber method for thermal analysis, evaluating heat transfer and energy efficiency, and the reverberant room and transmissive room methods for acoustic analysis, measuring the reduction of sound pressure levels. The main findings indicate that fiberglass offers superior thermal insulation, maintaining internal temperature more efficiently and reducing heat transfer compared to traditional mortar. In acoustic terms, fiberglass demonstrates notable noise reduction capacity, significantly reducing sound pressure levels and improving acoustic comfort. Furthermore, it is noted that the cost of a square meter of traditional mortar is 10%, while the cost of fiberglass is 5%. Traditional mortar has high resistance, while fiberglass offers medium resistance. These results suggest that the use of fiberglass coatings such as fiberglass can be a promising option to improve energy efficiency and comfort in modular constructions, presenting itself as an innovative and sustainable solution for the construction industry.
