Roof insulation before fitting headlining

I know this has done before and I am familiar with the principals of both thermal and sound insulation.

I have now acquired a roof lining for my 110 rebuild (thread) and I am trying to work out if there is a benefit to be had from insulation the roof in either sound, thermal or a combination before fitting the roof lining. Previously I did not have any insulation and just had the hardtop roof and roof lining.

I have insulated the bulkhead, tunnel, and seat box with alubutyl sound deadening (link). And I know people have successfully thermally insulated the roof using camping mats (which I would be looking to use) but any closed cell foam will do the job.



I have a 110 hardtop so there is no sunroof and no alpine windows fitted it is just an expanse of flat tin with the internal strengthening ribs. Is there any benefit of either foam or alubutyl if I am also fitting a headlining?

If there is I assume a combination is better than either individually but my next question is does the alubutyl need full coverage or would a large panel in the middle of each section do the job before then covering in foam?
