equal to 207.62 N and 200.59 N. These results are comparable to flexural strength of commercially available gypsum board. Thermal conductivity of panel with 26% and 30% bamboo fines is also well within the range of SP41. So developed panels in this study are a potential replacement of insulating materials. Panel developed in this study exhibit very high-water affinity as its water absorption rate is 0.069 and 0.068g/mm²s0.5 for panels with 26% and 30% bamboo fines when compared to bio-concrete. Thus, the panels are not suitable as over deck insulation material. The panels developed in the study used waste bamboo fiber and coir as filler and Bamboo mesh as reinforcement. Since these materials are a waste of industrial processes, they are available at low or no cost. Thus, the panel developed in study are low-cost sustainable material. However, the study has certain limitations, such as fire resistance, durability and field validation must be carried out for the developed panels. References Abdou, A., Budaiwi, I., 2013.
