Thermal Properties of Hemp Shives Used as Insulation Material in Construction Industry

The article presents the results of studies concerning raw hemp shives obtained from Polish crop industrial as a loose-fill thermal insulation material. study focuses mainly on measurements pore size distribution, conductivity and air permeability An increase in value coefficient (0.049–0.052 W/(m·K)) was demonstrated with an bulk density. porosity individual pieces is 78.7% predominant number pores diameter range 0.9–3 ?m. paper also example use tested material wooden frame wall. heat flow analysis performed various wall variants (insulation thickness: 100, 200 300 mm pressure difference 0, 5, 10 15 Pa). A clear influence variables temperature distribution observed.
