A Comparison of Biodegradable Fiber Insulation with Conventional Insulation

摘要

The apparent thermal conductivity(λ) for coconut and sugarcane fiber were investigated in accordance with ASTM C 518 over the density ranges 40 kg/m~3 to 90 kg/m~3 and 70 kg/m~3 to 120 kg/m~3 for the test temperature ranges 13.2℃ to 21.8℃ and 18℃ to 32℃, respectively. The experimental data were used to determine empirical equations for λ variation with density and temperature for both coconut and sugarcane fiber. Comparison of λ at 24℃ for coconut and sugarcane fiber were made with seven different conventional insulation from published data. The results indicated that the minimum λ for both coconut and sugarcane fiber are within the range normally associated with building thermal insulation. The λ variation with density and mean temperature for both coconut and sugarcane fiber were consistent with the behavior of loose-fill thermal insulation.
