To obtain the material parameters of typical bamboos and explore the distinction between bamboo and timber as well as among different bamboo products, flattened bamboo panel (FB), bamboo laminated lumber (BSB), plybamboo (BMB), bamboo scrimber (BFB), bamboo particleboard (BPB), and bamboo OSB (BOSB) were systematically tested for thermal and hygric physical properties based on the material parameter requirement of heat-air-moisture transfer model (HAM model). The items included density calculation and vacuum saturation test for basic properties, sorption test for moisture storage properties, capillary absorption test, water vapour transmission test and drying test for moisture transport properties, thermal analysis for heat storage properties, thermal conductivity test, surface light and thermal properties test for heat transport properties. The test results initially formed a data basis of thermal and hygric physical properties that could provide support for the bamboo application in the building envelope. The comparison with 18 reference timbers showed that the moisture storage and moisture transport properties of bamboo were generally lower, while the thermal storage coefficient that characterized heat storage and heat transport properties were higher. The comparison among 6 bamboo products showed that modification treatment improved the homogeneity, broadened the spectrum of material properties, and strengthened the distinction with timber.
