Hello, I'm laying 45cm 10mm thick porcelain tiles in my bathroom. The floor was uneven and the floor boards in a mess so I'm rebuilding it using 22 mm T and G P5 flooring (caberfloor) overlaying with 12mm exterior ply. I'll use a flexible grout.
Question is do I need to install noggins between the joists (40 cm centres, floor span 3m)? The caberfloor technical guidance refers to BS 5385 part 3 1989 and says that when preparing for tiles noggins should be placed at 300mm centres. Page 24 here:

This sounds like overkill. I've seen advice on tiling onto floorboards which only calls for overlay of ply, no mention of pulling up the boards and putting noggins in every 300mm. 1989 is a long time ago and engineered materials like caberfloor have come on a long way since then. Are caberfloor simply covering themselves against claims?
Ill do it if I have to and I suppose you could say I'll have peace of mind if I do but its another couple of days work which I'd rather avoid if it isn't necessary.
Many thanks in advance.
