In this study, the thermal insulating properties (thermal conductivity and thermal diffusivity) of hollow woven structures have been investigated by using the finite element method. In our FE analysis，the hollow structure has been greatly improved thermal insulation performance. Also，five types of unitcells with different sizes and three types of unit-cells with different shapes were modeled，and their thermal insulating properties were calculated and compared with each other. Based on the numerical results，it was confirmed that the model with high porosity has great thermal insulating performance. In addition to this，it was found that there is not a trade-off relationship between thermal insulation performance and equivalent bending stiffness as an index of flexibility.
