Abstract: Thermal conductivity values of compressed boards made of ground Arachis hypogea husk and Vigna unguiculata husk as binder at different percentage compositions at a temperature of 303 K were investigated using steadystate method. Other thermal properties including specific heat capacity, density, thermal absorptivity, and diffusivity values were also estimated for the prepared samples. Comparative studies of the determined values for the board at different proportions or ratios of combination of A. hypogeal ground husk with V. unguiculata ground husk reveal that thermal conductivity value decreases with an increase in the percentage content of A. hypogea husk contents. A fitting polynomial regression analysis reveals a correlation coefficient of 99.6%. The range of thermal conductivity values falls within the range of conventional good thermal insulators. Thus, the husks are potential ecofriendly raw materials for insulation board for cold building design and other thermal envelops.
