Green Glue with wall tiles for soundproofing?
I'm skeptical that these panels will help with soundproofing. I didn't see anything in the description of the material that called out it's soundproofing characteristics and it does not seem to be thick enough to do much.
Per the questions section at the URL you posted for Amazon:

Question: 
 How thick are these?
Answer: 
  Hi Steve. The panels are only 2-3 mm on the flat areas of the panel and hollow in the back. The embossed areas come out about half inch. 
Thank you
