Acoustic substrate

[Gazzer]

I have been asked by a builder who is doing work at some apartments if i could lay floor tiles in the bathroom and kitchens but there is a clause in the owners contract that say no ceramic floor tiles due to noise being transmitted to teh apartment below.
The owners want to know how effective the aacoustic membranes are and if suitable they would be willing to give it the green light, which a lot of the residents would like.

Anyone used it and what were the results ?

I've used it Neale, in very similar circumstances to yours, it really did cut out the impact noise

You can get acoustic adhesives as well.. so both combined would be better.

Hi neale I had to use it for same reason, I used Dural silent tread. Good stuff, this was before the acoustic adhesives came in. I believe it is part of building regs for flats etc,

Hi Sir Ramic, do you use BAL adhesive? They do an acoustic adhesive but I spoke to the rep not long ago and he says that the Viriset is better for stopping noise so they will be getting rid of it soon.

There are several of these available. Monarfloor, Celecta and Thermal ecconomics all do them. cheap(ish) and easy enough to use. I have seen them used several times under tiles without any issues. I reckon Thermal Economics is one of the better ones., If you want some contact details PM and I will sort you out a contact number. Its called Isorubber Top I think.

You would stick it down with a pressure sensitive adhesive. It also has robust detail status I beleive.

hi neale

is this any use ...

BAL Acousti-Bond is an elastomeric single-part adhesive which is accepted by NHBC for use with an approved matting system such as Regupol 4515 acoustic matting and an approved flooring adhesive such as Ardex AF200. BAL Acousti-Bond has been developed to achieve excellent adhesion to acoustic matting without adversely affecting the sound reduction performance of the floor. It performs in this way due to its formulation, which contains similar fillers to the materials used in acoustic mattings. These specially selected fillers give improved acoustic properties, compared to conventional tile adhesives, which contain more brittle types of fillers such as sand which can help to transmit sound.
When used as part of a system, BAL Acousti-Bond also provides a lightweight solution, which is particularly desirable when used on suspended flooring.

regupol very similar to Isorubber top. There are loads of these about these days.
Cannot see the science behind how the Elastomeric adhesive helps any better than any other adhesive though. The odea of the resillient matting is to prevent sound transfer due to impact by acting as a "shock absorber". it will work wether it is a tile, a laminate or any other rigid floor covering I think regardless of how it is bonded.

I think they have tried the BAL system before but were not impressed.

 

[Scott]

If its used on new builds then it should conform to the sound tests they carry out now, but then i guess that would depend on when that block was built and whats between your floor and the ceiling below!

Slippers. :lol:

did they use it with a accoustic matting? it contains similar fillers that the mattings contain so its not a singular option but a combined action...belt and braces etc

I dunno mate. I dont want to be using them as a guinea pig. Sounds like someone else has done that and failed. I dont really know their expectations.

Sorry Aston I simply can't see this. The regupol is a simple rubber crumb made from recycled tyre rubber. Are you saying that the adhesive contains rubber? It is surely the resillient mat that does the work in terms of acoustics regardless of the adhesive. Or is it not a cement based adhesive so acts as a second resillient layer? Not havin a go just trying to understand.

If you need an acoustic floor and there is a screed involved there will be either an underscreed resillient mat which allows you to bond direct to the screed or an over screed resillient mat which you stick down and then tile on to. If you have to acheive an acoustic condition to meet Part E then I think the nature and brand of the material should be specified for you.

Bear in mind as well that to avoid potential flanking sound at the edges of the floor you might need an acoustic mastic - not sure though.
