The Comparative Safety of Rockwool, Fiberglass, and Organic Fibers (a review)
Old 25th August 2017
Thanks; yes, I was thinking of increasing surface area (I want to make a booth out of it, so a pure UT recording booth). I want absolutely 0 reflectivity. Will 3" of UT reflect anything? What about 3" of 703, or Rockwool; will they reflect?

If so, could I cover them in foam wedges in order to reduce reflections?

What about spraying a mist of adhesive all over it before covering the insulation to keep the dust in?

I covered mine with jersey cotton sheets (it was the least expensive & flexible material vs quantity I could find). Should this suffice, or is a thicker material recommended?

i noticed the lights were illuninating A LOT of dust particles...and i became a bit paranoid... so i starting doing more research..

all the research says its safe. So you start reading through forums, and everyone is in agreeance its safe..then some guy posts something like....of course they will say its safe, they dont want to hurt their profits..or dont trust the govt agencies....or its safe until you start pumping low freqeuncies through and releasing the fibers...

i know i have told people its safe...but now that i think about about pumping bass through it....

it was the damn lighting in my room that got me all paranoid again.....Deep down i know i shouldnt worry...and i believe its safe....but i still cant let go

Glenn? Ethan? make me feel better!


so i took a shirt from my closet, brought it close to the light, and whacked it a few times...and you wouldnt believe the dust and fibers that came from it...

No matter where you are, you are breathing in dust...i cant imagine the abuse your lungs take. so why am i starting to get paranoid again?

hahahha i know i'm having the same thoughts... I mean i bought the most expensive vac cleaner with my gfs money and now i still see some particles. I decided I will wear a respiratory mask within my house.

I'm surprised this (attached) paper wasn't included in the initial selection.

Anyone here have experience with Woolly Shepherd, a uk manufacturer of sheeps wool panels?
