Hi I posted yesterday on the Kardnean forum and thought I'd post here too...... I've ordered Mohawk underlay to be put upstairs (after the dreaded Kardnean is pulled up) and I wonder if anyone has any experience of this underlay? http://www.underlay4u.co.uk/carpet-...tcushion-11mm-carpet-underlay-270-53-1022.php It is fairly new, but supposedly has an impact reduction of up to 55db. The impact noise I have from above is HORRENDOUS. I was going to get the Colour Red or Dreamwalk underlay (think that's the name of it), but then was recommended to Mohawk which is a 55db reduction rather than 44db for the other two. Any thought or advice on best one for noise control - or any other tips? Thank you in advance!
