Hi I wonder if anyone can help. We live in a first floor purpose built flat, with concrete floors. We used to have carpet but wanted to get a hard floor. We looked around and decided on Korlok as it says it's suitable for apartments because of its good sound reduction properties. Now we've had it installed our downstairs neighbour is complaining about the noise, saying she can hear our conversations, and even our mobile phones vibrating. Is the difference between carpet and Korlok that massive in it's sound proofing? We have just had a baby (10 months), and we think this is probably the real cause of the increased noise perception, as there's lots of noises like him banging and us singing to him etc, which she would have heard if we had carpet or Korlok. To show we are taking the issue seriously we have now covered 90% of our living room floor with rubber play matt tiles, and 2 rugs, so surely that must be more sound proof than the carpets with underlay we had before? Can anyone recommend anything we can do. I want to avoid having to pull all the flooring up to put underlay underneath, so any other recommendations would be good! Thanks for any help.
