I've found the bitterness of dandelions to be transformed into a big positive when mixed with feta. I make filo pastries with dandelion and feta inside and the flavour combo is great (even better with some fennel mixed in).

I think there's a grant for external insulation available here too (from registered installers though) - look into it!

I think the most eco of the common external insulation materials (that are easily ordered and installed in Ireland) is Rockwool. It's not on the same level as the options you mentioned, but it's not too bad, and one of the most effective.

I'm down in cork starting up an little permie orchard on half an acre, just got started. If you want any recommendations on fruit trees I've just finished the research/ordering stage.
