LVP or laminate for 2nd floor condo with STC >65

[Rhona Didi]

Hi All

For a 2nd floor condo am I better off with LVP or laminate for noise reduction?

HOA requires an STC of 65+.

Are there LVP or laminate flooring options that already have an attached STC pad rated 65+ ?

Thanks

To determine the STC i need to know the floor system.  What is it constructed from   I assume its something like (2) layers GWB on metal channel on joists or trusses at 16" on center w/ 3/4" floor sheathing and 1" gypcrete and insulation.  The system I described above could get you a STC rating of 59.  The system should not consider the flooring in most cases... there are exceptions.  I would begin with getting information on the floor system to see if they consider the finish.
