Comment on Price of electricity in Finland peaks at 2.35€/kWh today. Keeping my tiny granny cottage warm costs me over 50 euros for a single day. It's negative 25C (77F) outside.

  Polyurethane is better insulator, doesn’t absorb moisture and doesn’t require a vapor barrier but is also much more expensive.

      Wood fiber will burn slowly without any toxic fume. Its not perfect but better than most oil derived products.
