Influence of temperature and moisture content on the thermal conductivity of wood-based fibreboards
Original language description
Temperature and moisture content are important parameters affecting thermal properties of wood and wood-based materials. Quantitative data are required to better characterize the thermal performance of fibreboards. The aim of this work was to assess thermal conductivity of insulation fibreboards at different temperatures (ranging from-10 to? 60oCat10oC increments) and moisture contents (gravimetrically determined after conditioning at 15, 50, 85 % RH). Thermal measurements were done conducted with at stationary boundary conditions. The relationship between thermal conductivity, temperature and MC of samples was found by fitting data to a second order polynomial function. Moisture behavior was characterized by applying the Hailwood-Horrob-in (H-H) sorption model. The single-hydrate model was used with the equilibrium moisture data at each conditioned climate step, starting at 10 % RH, up to90 % RH, at 10 % RH increments.
