Thermal conductivity and water vapor transmission properties of wood-based fiberboards

Popis výsledku v původním jazyce

Low density fiberboards are wood-based materials widely used in engineering as thermal insulators. Exposure to environment with high temperature and humidity can lead to changes in physical properties of this porous material.Temperature and moisture content are important parameters influencing mainly thermal properties of wood-based materials. Thermal conductivity of commercially available insulation fiberboards was measured by using the stationary measuring device heat-flow meter (HFM 436 Lambda). Therelationship between thermal conductivity, temperature (ranging from -10 °C to 60 °C)and moisture content (established gravimetrically at 15 %, 50 % and 85 % of relative humidity) was found. The moisture behavior of the material described by adsorption and desorption isotherms was explained. The sorption models of Hailwood-Horrobin (H-H)and Dent were used and compared with the experimental values. The H-H model was in a closer agreement with the measured data, although the total sorption
