A wooden house is just as good as a stone house in terms of thermal insulation. The manufacturing method is nowadays so modern and well developed. The mold problem exists with every construction method.
That is simply not a construction method for me either. The contract is created, then some time passes and the date arrives, but unfortunately the weather god does not cooperate. The date must be met and then the prefabricated house is erected in the rain. Conclusion: The moisture damages the construction.
