An environment-friendly thermal insulation material—binderless
cotton stalk fiberboard was developed from cotton stalk fibers
without resins and other chemical additives. BCSF with a density of
150–450 kg/m3 and a thickness of 25 m
conductivity was found to be correlated with the boards’ density in
a power pattern. Since BCSF is made from natural and renewable
raw materials and without any chemical additives, it is environment
friendly and can successfully compete with other insulation
