Abstract

The present work has as objective to characterize the thermal conductivity in the wood of the species of Pinus caribaea, for its practical application, as insulating thermal. They took 10 trozas of 4 m at random of long of the patio of the sawmill, of the Integral Forest Company (EFI) Macurijes, which were divided in 3 sections that correspond base, center and tip. The cut samples were taken out in traverse sense to the longitude of the fiber, looking for the trozas bigger than 13-diameter cm for 90 samples. They underwent the drying process to determine the density of the species and the humidity that it is of 18%, classifying you as commercially dry wood. The biggest value of density in the different positions of the trozas, was obtained in the base with a value of 0, 9094 g/cm³, followed by the tip and the center with the smallest value 0, 7033 g/cm³. The thermal conductivity was bigger in the base with a value of 0, 2263 J/s m°C and smaller in the center with 0, 1772 J/s m°C. The biggest values of typical deviation, as much for the density as for the thermal conductivity are in the trozas of the means. It was obtained as a result that the coefficient of thermal conductivity in the wood of Pinus caribaea is low with a value average of 0.198 J/s m°C; the thermal conductivity depends lineally on the density.
