Design of Roof Thermal Insulator Using Coconut Husk Fiber with Waste Interior Tire Rubber Strips as a Covering Material

The continuous escalation in global temperatures has pervasive and profound implications for vaiour facets of life. Notably, It significantly impacts human well-being, the ecological balance, energy consumption patterns, and the availability of natural resources. A certain community in Catanauan Quezon specifically Barangay Madulao Sitio NFA are still hesitant on purchasing the conventional thermal insulator in their residential houses, even though the heat temperature in the area is high due to the fact it is near the ocean. COmpared to the people who are living in the central part of the province, mostly their earnings from their occupation are only minimal to their needs. In order to address the issues regarding the heat temperature, the researchers will innovate a roof thermal insulator purely using coconut husk and waste tire rubber as its raw material. The study involved conducting specific tests to evaluate the potential of the design mixture. This test included the determination of thermal resistance and heat insulation. The study found out that the volume mixture of 0.03072 cubic meter of coconut husk fiber and 0.00576 cubic meter of interior rubber tire produced a value of 5. The prototype's thermal resistance value of 0.07 (m^2-°K)/W meets the minimum requirement according to ASTM C655. In terms of its temperature loss and heat loss, it was calculated to be 79% - 80% and 17.34 Watts respectively.
