A slight correction:
34mm of polystrene is equivalent to 150mm oak. (but that does not affect the vaildity of your argument)
another slight correction: i looked our tables and there was 10 fold insulation value.
We use pruce or pine as " standard dry wood". Never oak. We do not have oak walls.
A normal economical insulation board what we say styrox, it has 5 fold insulation value.
You have 5 fold value. That board has bigger air bubbles and it moves heat better that micro bubble stuff.
