Waterproof/resistant Plasterboard, Really?

[JMC tiling]

Hi guys,

went to look at the job at the weekend, all walls were plasterboarded (plasterboard has a blue front) in bathroom so I recommended the customer have the shower area tanked which they had no problem with until the builder told them that the plasterboard is a special water-resistant PLASTERBOARD. I have never come across this before, has anyone else? got no pictures I'm afraid but I assure you its nots a tile backer board, definetly plasterboard of some sort.
Cheers! John. J.M.C Tiling

That's Db board for noise reduction. The green one is moisture resistant

Its possible it was green actually will check that when I go back to start, so you would say this is as good as a tile backer board such as hardie?

No, it's moisture resistant and that's it...certainly not waterproof.
