Re: Ceiling tiles ..?
Well when you are not build stuff to code why not. The titles are hiding a junction box witch is a no no. I'm willing to bet that electrical junction box is over crowed too. I know in my home state of California if you run cat cable that is hidden by those types of ceiling titles you need cable trays. Some counties require the cat cable to fire rated if going through ceiling titles like that.
Also looking at that picture it looks like it had a more permanent type of fixed ceiling that was hiding the electrical junction box which is an automatic fail of the of both Canadian and US national electrical code.
