It don’t see anything essentially contradictory about these. However Regulation (a) is one of the dumbest things I have seen in a while.
It’s a clear sign that the people writing these regs have probably never set foot in an apartment block less than 10 years old (if at all).
Think of all these older buildings where the only insulation on timber floors was carpet (and very effective it was too). Hey, lift the carpet and you have a free timber floor … and a steady stream of complaints form your downstairs neighbours, arguments, visits to NCAT and misery.
