[John Straube]

In some ways John I am heartened to hear you have the same problems in the UK as we do in Canada and the US.  Your quote could have been spoken with a drawl or a twang and been completely authentic.

In 35 year of being a building control officer (building code official) this myth is still as dangerous as ever, even with some proffessional clients.
