Reduced some noise from flat below, needs rockwool panels for proper effect
I bought this when I lived in a flat with noisy neighbours.The flat was poorly done up, laminate bosrd of stopped short of skirting board..I'd already got the rockwool sound panels against the wall to dampen noise from below.I went around all the skirting boards to seal all gaps.The rockwool sound panels absorbed way more sound as can be expected.However doing this led to a 15%sound reduction. This may not sound very significant but it reduced the reverberation of their voices and noise and so softened some of the noise to a muffle.

Great value
I have used this to stick thermahoods over my led lights, bonds well to both the plasterboard and plastic. And great piece of mind knowing this will add protection against fires.

Can't comment on it's soundproofing as I don't know what ordinary sealant would do. Very easy to use
