Good study on insulation sadly USA based but probably applicable.

I don’t understand why he did the test without protecting the insulation with vapour barrier. Any wet insulation will be conductive, but the PIR is foiled and close cell. Not fair in my opinion.

The polyusio stuff has a built in vapour barrier but the others don’t

Wool absorbs moisture and then releases it, up to around 35% of its own weight without damaging surrounding structure, is more environmental too.

Not a fair test I agree.
