It is suitable for tiling on.
Like any substrate though, you need to keep within the limitations of combined weight it can take.........combined weight being, adhesive, tiles and grout.

12.5 mm PB is about 30kgs per meter but as ROC says this must be tile, addy and grout! general rule of thumb is 4kgs per mtr for addy and grout!
the exact weights can be found in the white book by BG

I would advise that you use Aquapanel or similar cement board in the wet areas. Any water creeping through a pinhole in the grout will knacker the plasterboard substrate.

you shouldnt be dabbing tile adhesive, it is applied in a thin spread then combed up! doing it that way keeps the weight to 3-4 kg per meter!
and use plaster boards with Polystyrene backing ?
if you use insulated plasterboard this shoud be mechanically fixed as well as dot and dabbed!
or batten the walls and screw plaster boards ?
if you batten then use a kingspan insulation then use hardi backerboard as that hold 50kg per meter of tile!

you can tile straight onto plasterboard as long as your tiles and adhesive and grout DO NOT EXCEED 30KG per meter
just remember your tiling is only safe as long as the substrate is secure fixed!
thank you paul
your welcome!
