The difference between the heat flux through the centre of a
chamber and the flux measured near an internal wall was about
2 W/m2
for the sample S3; the mean heat flux through the joint
was 25 W/m2
, the mean heat flux through the centre of an internal
chamber was 33 W/m2
(Fig. 14): the male–female interlock joint
has a thermal resistance higher than the panel, because of the particular internal structure of this system, as confirmed in Table 5.
For this kind of structure, the global thermal performance in situ
conditions could benefit from the joints
