  not plastic, even so would be hard to light these up.I held a lighter to some just to see took much to get one to start on fire my manufactered studio damping melted right away producing blk smoke and melting plastic seems to me the cardboard cartons would be safer.No toxic fumes and no dripping plastic .YMMV

    Well, it is all for the good that you tested the egg cartons. I never have.

    In my acoustical consulting, I tell clients never ever to use anything that is not top-rated for public spaces. The regulatory authorities are perfectly content if you clad your own walls with stuff that does support combustion and emits toxic smoke.

    Codes are a minimum. It is wise to exceed them.

    I also want to point out that your lack of bad luck with egg cartons does not mean that someone else in a different part of the country might not get egg cartons that will not self-extinguish and will support combustion.

    Compressed fiberglass with fire-rated cloth covering is usually a better alternative. And not all that expensive.

    Cordially,

    JM

  NEVER use a soundproofing material that is not Class 1 Fire Rated.

  I heard a story of a salesman for a company that markets Class 1 Fire Rated acoustical foam who got some samples of a competitor's non-fire-rated foam, and cut it into small pieces to demonstrate what happened when it touched a source of ignition. The first time he tried it the sample went up like a torch and set his sleeve on fire.

  Remember the Station night club disaster in Rhode Island? 100 people killed by non-fire-rated acoustical foam.

  Better to be safe than sorry.

    I was just at a legal seminar showing how incredibly flammable that polyurethane "egg carton" type sound proofing is...those poor people at the Station Night Club in Rhode Island never had a chance...I've seen this stuff widely advertized and still no Federal Law prohibiting it's use or requiring prominent markings stating the flammability issue...this material is only suitable for packaging, and never for building interior surfaces!
