Zero Block, a floor noise mat  construction brand of the mat company Parklon,  announced on  the 5th that it has  launched a  service that  allows  customers to  directly designate a construction date. Previously, construction dates were  designated  sequentially through consultation, but with the  launch of  this service,  customers can receive construction service on the  date they  want. An  official from Zero Block  said , "We  started this service so that  customers can receive construction more conveniently due to a  surge in  construction inquiries due to noise  problems between floors ."The Zero Block Bread Foam  Polyurethane (TPU) puzzle  mat, which is a  mat that a professional construction  team visits and  installs at a  customer's  home,  is 18mm thick and 30mm thick . Through the  lightweight inter-floor  noise test, about 71% of the noise  reduction effect was certified to  reduce 70dB noise before construction of  the 30mm  standard mat to  20.5dB after construction.
