Abstract


Heat insulator is very significant in maintaining comfortable and hygienic indoor climate at low ambient temperature. As commercially available thermal insulator are more expensive, there is a need to find alternative sources to lower the cost involved. This study examined the potential of water hyacinth (Eichhornia crassipes), swamp taro (Cyrtosperma merkusii), and arrow leaf elephant's ear (Xanthosoma sagittifolium) as an alternative heat insulator by applying thermal conductivity of all samples under the normal outdoor temperature. The results of thermal conductivity of three experimental plants were compared to commercial heat insulator in triplicates for three trials using model houses exposed to sunlight. The commercial heat insulator had an average temperature of 36.83°C while the insulation boards made up of water hyacinth fiber had an average temperature of 36°C, the insulator boards composed of swamp taro fiber had 36.5°C and the insulation boards made up of arrow leaf elephant's ear  fiber had 37.67°C. It was found out that the water hyacinth has the lowest average temperature as compared to the sample set-ups. It indicates that the water hyacinth is the most effective alternative heat insulator for ceiling.
