I'm attempting to design some composite wall panels and one of my parameters is the differential temperature between the interior and exterior of the wall. For the life of me, all I can find thus far is:
1) The blurb shown below from the PCI manual which would seem to imply that things might be worse that 40F for common, interior wall panels and;
2) Examples, every one of which seems to choose 40F as the target value without justification.
So my question is this: is there a tractable way to figure out what the temperature differential should be? Some tabulated data someplace? Or is everybody just rolling with the 40F differential without digging any deeper into it? I've no doubt that a building envelope consultant would be able to work this out somehow but those expertise are not available on most of these kinds of projects.
