I just want to make sure this does not happen to anyone else out there. This has been the worst nightmare of my life. I just built my first home, used JM Spider after reading about it, and thinking that the stuff set hard in acrylic.

Well, turns out it sets to a feathery type of wispy stuff that blows all over the place. It got in my HVAC system plenum and when I turned it on it broadcast microscopic glass fibers all over my house. I left after two days. I still have chest pain. My hands were raw from trying to clean the stuff up.

We have stripped the entire HVAC system and I still can't clean this stuff up. It's like a contagion that sticks to everything. This stuff is NOT safe, it is NOT Solid, it is 20 times more dangerous than batts because it is microscopic glass shards set in a foam and when the foam drys, the stuff crumbles and you inhale it.

Stay away from it. Even if it hadn't gotten in my HVAC, they would have had to have wiped clean the entire house two times before I could move in because it hangs around and sticks to everything.

It took a week of blowing a huge box fan in the building site after they installed it to get the visible plumes and tufts of the stuff out of the house and the air.

Stay away. Stay healthy. Fiberglass is a known carcinogen. I wish I had realized the stuff doesn't harden in that acrylic media.

Wow, that is scary. I hope you don't have any long term health issues. Everyone needs to do their homework. Read and post to boards like this and others that have a lot of knowledgeable people posting questions and answering them. here is another one I really on also: www.startinsulating.com
