Building insulation type materials were never designed to be used as an acoustic tool. They were designed to keep your room warm and cold. They do not provide the proper rates and levels of absorption for music and voice.  

Thanks for the info. That’s interesting because a lot of professionals use those same materials esp many Grammy award winning Mastering Engineers. I’m actually the same guy that left comment on You tube about the ECOSE question. I ended up going with GIK Acoustics but takes two months to ship. I discovered that Rupert Neve himself used some of GIK Acoustics stuff. What are the safest absorption . materials out there? Do I send you photos of my room for the analysis or how does that work?
