Good thread. Not a subject that comes up much, but worth knowing. I'm already aware of the Ditra Sound but that can work out fairly pricey. but as an alternative:
Firstly, Hardibacker over the chipboard (6mm)
Secondly, Another one we can add to the list is the CMS Regupol 4515 Multi. approx £150 per 20 sqm roll. Fixed with their own ReguBond (about £50 per tub and covers upto 40 sqm). Where the matting meets the wall, leave a gap of 3-4mm and inlay some impact isolation tape (approx £25 per 20m roll)
Thirdly, Tape the joints with high tack tape (£12 for a 50m roll).
Lastly
tile with BAL Singlepart Fastflex (This can also be used to fix the matting down using a mosaic trowel, but will work out more expensive than buying the Regubond).... Use a flexible grout.
Finishing touch, cut off the excess impact tape just below the height of the
tile, and fill/cover the edges with Silicon.
I presume any S2 adhesive would work out cheaper but check with the manufacturer if its suitable for acoustic matting.... (Would Tilemaster Ultimate S2 work on this type of flooring
