ᐅ Cavity Wall Insulation or Air Gap? Advantages and Disadvantages?

JappsonHello everyone,
During the planning of our wall construction, the architect designed the following layers:
24cm (9.5 inches) pumice block, 8cm (3 inches) mineral wool, and a 2cm (0.8 inch) air gap.
We have now noticed that our bricklayer did not include the air gap but instead installed 10cm (4 inches) of mineral wool. After showing this to the architect, he didn’t consider it a problem and said it was negligible. As far as I understand, this means we now have a “cavity insulation” since there is no air gap.
I tried to research this online and only found one study that supports this statement.
Do you agree with this view?
Thank you very much for your help.
