Insulation of parting walls

neerb

Hi

Just looking for advise on parting wall insulation - I am renovating a house and the builder put on 50 mm insulated slabs however I can still hear the television clearly in the neighbors house

I have heard about calibel 42 mm - How effective is this? and could I now put this on top of the insulated slab?

Many thanks in advance on this query

"Party Wall".

the builder put on 50 mm insulated slabs

That sounds like heat insulation, not sound insulation.

Ideally, sound insulation would be in the order of 150 mm thick, which creates maximum interference with noise. Fibre glass or rockwool type insulations are usually used, placed on dry lining that isn't in contact with the party wall.

Many thanks for your reply - the one they are proposing on using is the calibel board 42mm boasting acoutic insulation ? will this work ? I dont have much space so 150mm would be too much to loose.

Many thanks in advance

Actually, "parting wall" appears equally good.

There's a product called Mustwall. I've seen it used in a recording studio and it seemed to work well.

There appear to be a few suppliers in Ireland.
