Missing information about Marmox tile backer - Tile Advice

[jev]

Planning to install brick imitation porcelian tiles 250x250 size in dinning room, decided to go with studs on brick wall ( 20.5mmx 45mm,because need to cover some pipe work) and will cover with Marmox 12.5 . There is very light official manual, so please, could some one explain me a bit more in details:

1. official manual states that 20mm sheet goes on 600mm centres, 10mm sheet goes on 300 centres, what about 12.5? 400? if so then sheet is 600 and centres 400 how to fix them? horizontally? what about 1200mm edge support ?
2. in official manual nothing said about nogging, do i need put noggins to support end of sheet? if every 300m centres i would think is not needed?
3. official manual says to use drywall screws with Marmox washers, on this forum found people advising to use SS ones, would i need SS if installing not in wet area.

Thank you for advice!

1. Studs at 300mm on 12.5mm
2. I add noggings on board joints to stop any flex.
3. I use stainless screws in wet areas, but it’s not really necessary, goldscrews from Screwfix will be fine.
