The aims of this research were to study the production processes and properties of thermal insulation
produced from pineapple leaves using natural rubber latex as a binder. Thermal insulation boards were made
by spraying the pretreated natural rubber latex onto pineapple fiber to form a squared thermal insulation with
the size of 20 and 1.5 cm thickness. Test results on thermal and physical properties showed that the thermal
insulation produced from pineapple leaves fiber exhibited a considerably good thermal insulation. The thermal
conductivity of the thermal insulation was 0.035 W/m.K with density of 210 kg/m3, which was closed to the
commercial insulator. The result showed that pineapple fibrous insulator was extremely potential to replace the
synthesis fibrous insulator.
