According to the authors cited, constant thermal conductivity values can result in actual construction performance differing from project forecasts, with increased energy consumption, possibilities of condensation problems, and lower occupant comfort. These values are included in the central frequencies of 1/3 octave bands determined by ISO 354 (2003). In this sense, we highlight the values obtained for the panels in this work, which are higher than the cited codes. Crocker, M. J., and Arenas, J. P. (2007).

Vegetable materials have a porous microstructure, a feature that may be more influential on thermal properties than the porosity of the product made from these materials. The results obtained in the present study emphasize that the absorption coefficient can be influenced by the sample density, as a sample of lower density can present a structure of greater porosity. By the test formulation, a probability (P)-value higher than the level of significance implies that the distribution is normal and that the variances are homogeneous (acceptance of the null hypothesis H0), validating the ANOVA model. Table 2 shows that the variations in the pressing pressure of the panels affected the property of thickness swelling, at 2h and 24h, as demonstrated by an increase in the swelling associated with the increase in the porosity of the panels.
