Insulation Capacity of Refined Sawdust and Coconut Coir as Plyboard Wall Cladding

This study aimed to investigate the insulation capacity of refined sawdust and coconut coir plyboard as wall cladding.The refined sawdust and coconut coir plyboard as well as the commercial plyboard were tested separately before 1 hour exposure to sunlight and after 1 hour exposure to sunlight.The plyboards separately placed inside the prototype room made of galvanized iron and were tested by thermal conductivity meter.Data were analyzed using mean and Mann-Whitney U Test. Results showed that refined sawdust and coconut coir plyboard can be used as wall claddings of our houses because of its good insulation capacity.Also, refined sawdust and coconut coir can be utilized as interior building material.The refined sawdust and coconut coir plyboard and commercial plyboard have significant differences in temperature after 1-hour of exposure to sunlight, therefore, refined sawdust and coconut coir plyboard have be1er insulation capacity than commercial plyboard and it is environmentally and economically friendly.Explore more uses of refined sawdust and coconut coir plyboard.
