When we decided to renovate our home, the first thing I had in mind was that this time I will not leave my carpets unprotected. So I searched online and find pretty good reviews about the carpet underlay products that Airstep offers. So we went to the nearest carpet retailers and a decision was made. We have chosen Acoustalay - Acoustic floor underlay that offers sound insulation, and so far we are very satisfied. I will recommend Airstep to anyone.
