LVP over very thin, hard carpet?

[Karen F.]

In a  Dplus area, 2nd floor unit, considering installing LVP.  Currently there is that extremely thin, hard, cheap landlord carpeting (and also an area with cheap thin stick on hard tile squares).  I was thinking that the very thin hard carpet could serve as a sound insulation layer, and just installing click together LVP right over the thin carpet and the thin hard stick on tiles.  Also, how to get an LVP that will wear well, for cheap?

Any advice?

Quote from @Jonathan Greene:

I don't think the LVP will feel right with carpet underneath and it's not a sound installation practice to have that buffer layer there. @Bruce Woodruff can weigh in as well. There are so many options for LVP now, from lower priced to higher.

Yeah, that's not a proper install, you'll have problems. Even cheap carpet will allow movement...could void the warranty as well. I'd use an approved underlayment.

Pro Tip: If it's cheap, it's not good.....at least spend in the moderate range.
