Is fiberglass safe?


Hi everyone!
I'm in the process of building a dedicated listening room. Design is done by Rives Audio. I've reached the point where LF traps need be filled with fiberglass. Thing is I became kind of concerned by reading contradictory opinions on weather fiberglass is safe or not. LF trap walls are to be covered with fiberglass and closed by a panel of fiberglass covered with Guilford-of-Maine fabric.
I shall contact Richard from Rives Audio too on the issue but thought of getting a second opinion. Any feedback more than welcome.
Cheers!

As long as the fiberglass is contained within an enclosure and clothed by material to prevent airborne fiberglass from escaping, you are okay. Fiberglass is non-toxic, but can irritate the skin or if inhaled, your respiratory system. If you have little kids that maybe poking around your bass traps, you might consider changing out the fiberglass with Rockwool, which is equalyl effective.
Cotton batting used in futons works, so does speaker stuffing or wool. Fiberglass (glass) is not broken down by the body and once inhaled is with you for life.
Don't worry...you just don't want to inhale lots of the dust or get it on your skin (itchy). It is not dangerous or anything like Asbestos but it is an irritant and too much exposure is bad for you.
If the room is finished you might want to build them in the garage or outside if possible. Wear a long sleeve shirt and a dust mask. Goggles would be appropriate if the wind is blowing.

You may want to check out different manufactures... Some fiberglass insulation has a nasty odor to it. When covered with drywall there is not any problem. In your case where it will be covered by a porous material good chance the smell would pass through.

I recently had fiberglass blown in my attic replacing 30 year old nasty stuff that floated in the air as a fine particulate. The new stuff they use is not as fiberous, shaped liked cheese curls, doesnt break down as easy. I still would cover it with fabric that got down to the 10 micron range. Might consider contacting your local insul installer for a couple of buckets of that stuff.
Alternatively you could use cellulose HomeDepot offers for blow in.
