The rising of yearly temperature anomalies creates the stress of finding the right thermal insulator that ensures durability and efficiency while also being thoughtful about the financial feasibility of thermal insulators. This study analyzes the viability of employing sawdust-coconut husk composite wall tiles as sustainable thermal insulators for architectural applications and bio-friendly thermal insulators. The research focuses on repurposing agricultural waste to boost thermal insulation efficiency and promote environmental sustainability in construction. Methodologically, sawdust and coconut husk composites are made with resin, and changes in thickness and size are tuned to match real-world building conditions. Thermal performance is tested using temperature differential measurements utilizing thermal imaging techniques. Economic analysis examines the cost-effectiveness and potential financial benefits of using certain materials. The study informs and interprets its methodologies to provide our novel conclusion utilizing data from the body of prior literature and related research. By measurements of 30 x 20.5 x 5, with the Thermal R-value of 0.615 w/mK rises, succeeding in innovating a thermal insulator with High R-value and low T-value that contributes to the upper hand of control over the conductibility of these thermal insulators. Additionally, the SAWDCOCOHUSKS provided noise-canceling variable advantages, calculations displayed a peak sound reduction coefficient of 0.5 at 8 kHz and efficiently reduced noise across the 5.5 – 8 kHz frequency range. Limitations include resource limits such as infrastructure, financial assistance, and material availability for thorough testing. By tackling these difficulties, the research seeks to contribute to the improvement of sustainable building materials and guide future practices in environmentally conscious construction.
