I live in a flat, converted from a large house in 1960 or so, with no
sound deadening between ceilings and floors.

I have agreed with my upstairs neighbour that we will investigate the
possibility of sound deadening underlay.

Does anybody have any experience of whether or not this stuff works and
how effective it is?

There's loads of them around in thicknesses of 3 mm to 18 mm and they all
claim to be effective but are they really?

Main issue is impact noise although I can hear some speech through the
floor as well.

Thanks.

This is as bad as it can get, but don't bet on it

Read Part E of the Building Regulations Approved Documents:
