Abstract:
This study focuses on an experimental investigation of thermophysical properties of date palm
wood (Phoenix dactylifera)from Biskra oasis in Algeria. The goal is to use this natural material in
the manufacture of thermal insulation for building. Certain parts of these palms were tested. The
effect of fibers orientation was also studied. Furthermore, a comparison of its properties with those
of other materials known in the literature is performed. As results, therenewable partsof date palm
are the mostinsulatingand lightest, comparedwith thetrunk wood. The effect offiber orientationon
thermal conductivityis notsignifican. Although, the date palm wood is a good candidate for the
development of efficient insulating materials when compared to the other natural materials
