Calculative processes of thermal resistance.

Building member	Materials	δ (m)	λ (W/mK)	Correction factor	R (m^2K/W)
Bamboo steel composite wall (wall1)	Cement mortar	0.015	0.93	—	0.016
	Polystyrene board	0.02	0.042	1.1	0.433
	Bamboo plywood	0.01	0.17	—	0.059
	C-type steel	0.001	58.2	—	0.000
	Mineral wool	0.098	0.05	1.2	1.633
	C-type steel	0.001	58.2	—	0.000
	Bamboo plywood	0.01	0.17	—	0.059
	Cement mortar	0.015	0.93	—	0.016
Total					2.216

Note. The thermal resistance of C-type steel can be neglected due to the thin thickness and high thermal conductivity.
