Sand like substance in loose-fill fiberglass?
This is an asbestos question. I know these can be tricky to navigate on a forum. But my question is hopefully specific enough.
I have an old house (circa 1910’s) with retrofitted blown-in fiberglass loose-fill in the walls. Not sure when it was blown, but possibly in the 90’s. It’s definitely not vermiculite.
Anyways, I’ve pulled some out of the walls and noticed that a pile of what looks like sand accumulates under the pile. I found this concerning. Does anyone have experience with a sand like substance being present in loose-fill fiberglass?
I know sending in a sample is the only sure way (and I will likely do that) but I want to have some idea of experiences with this.
