Some cladding products leave a cavity to be filled with insulation, vented to avoid pressure differences driving rainwater in, but with firebreaks at ceiling levels and windowframes. Others have the insulation built into the cladding panel.
The integrated version is easier and quicker to install, since you don't have to separately handle and secure the insulation, but if installed too far from the bricks and without proper firebreaks, you've created a chimney.
This is the product brochure for the cladding (Reynobond ACM which stands for Aluminium Composite Material):

It says nothing about insulation, it just seems to be for cosmetic purposes. Can anyone confirm that who knows what they're talking about? @hoefla ?
