   Fair enough. I noticed construction practices are very different by   
   country. We have some really flimbsy accepted practices in the US for new   
   construction. The obsession here with insulating everything results in   
   buildings that will mold and rot from the smallest of water leaks. You can   
   flood and older building and since it's not sealed up like a plastic   
   freezer bag, it will dry out and be fine. The codes vary from state to   
   state as well. Some places are more tolerant of fiery death traps and   
   buildings that collapse while being built.
