My 1st Job Gypsum backer board, Mapie grout and soundproofing. - Tile Advice

[White Room]

Would you really tile straight onto a sound proof membrane? I thought backing board was designed to take tiles. This sort of thing.... https://www.amazon.co.uk/Advanced-Acoustics-Soundproofing-1-25m-thin/dp/B00BSBMFBM

There's this Mapei product for tiling onto products - http://www.mapei.com/GB-EN/Products-for-Ceramics-and-Stone-Materials/Acoustic-installation-systems/MAPESONIC-CR

Also Ditra-Sound to throw in the mix

You guys are so great!!! the Mapei product looks good for footsteps but not airborne noise (coming up from his stereo below). Couldn't see in the spec - can it go down onto my chipboard floor?
Does it matter where the membrane goes - its blocking sound anywhere surely. I'd feel uneasy aobut tiling onto that stuff and not the hardie board. xx

Well - thats two products to look at tomorrow - can ring the manufacturers... Not gypsum then...?

The product you showed on Amazon is mainly for walls, airborne sound is probably a fair bit more complicated, if you read the questions and answers on Amazon there's some good info.

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 silicone.

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 @Lee@TileTown?)

OK
Very nice chat with Barry at CMS Danskin. He currently recommends Soundlay but not 100% sure about ceramic tile. He'll let me know tomorrow and I'll report!

laying chipboard will only remove some but all of the airborne sound transmission. you will also find that if you screw it down impact sound will transmit very easily so he will hear you walking on it. there are a few acoustic membranes suitable for tiling onto that divorce the substrate from the top of the floor which will help with impact so you might want to put that down before inviting your neighbour to listen. as a general rule the more mass you can add the better for airborne sound and the more divorcement you can acheive between elements the better for airborne sound.

i could offer a screeded system but fear this might add too much height. this would involve a 30mm sound blocking board then a 40mm timbre screed on top.

That makes perfect sense.

Yes. My ceiling is just over 2m high.

Well in conclusion - a solution presented itself. This stuff (the 5mm) will block airborne sound. Barrier Shield | Barrier Mat | Thin Soundproofing - http://www.noisestopsystems.co.uk/wall-soundproofing/barrier-shield

I now have a moral dilemma however. Do I tile above someone's bedroom where my tenant might walk through the kitchen (directly above) at any time day or night? I could spend on impact sound blocking for my neighbour's benefit but he can contribute nothing financially. An accoustician had told me that tles have been banned on upstairs flats in London because of all the trouble they cause... is this really so?
