I have a cottage with the first floors made from a single layer of T&G boarding. Noise from downstairs travels up.
I am concerned about airborne noise, not impact noise. We are proposing to re-carpet all the upstairs rooms this winter and I see two options.
Firstly, I could use an accoustic underlay.
Secondly, I could lay a layer of dense material such as MDF boards.
I could also grout the seams in the T&G boarding to fill any gaps.
I would much appreciate any advice on which would be the more cost effective option, MDF or specialist underlay.
