Tell me I'm paranoid and it's not Asbestos...
3 Attachment(s)
Opening up the upstairs knee walls of my 1940 bongalow today so I could figure out how much insulation I needed to a I found a mess of insulation. Looks like it was attached to the roof rafters and fell down over time.
From what I could salvage it says its Red Top Insulating Wool made by United States Gypsum Company. I've been searching on-line to verify that it is or is not asbestos with no real luck. If anyone is knows for sure please let me know. Thanks

It certainly could contain asbestos, 1940 was a year when a lot of asbestos went into a lot of different products. The only way to determine if there is asbestos in your insulation is to get it tested. This is easily done, you take a sample to a certified laboratory, you pay them, they test it, they tell you if there is asbestos in it.

It does not look like asbestos. Looks like rock wool. But see Daniel's post.

Been going though sites about rock wool, slag wool, and asbestos. Can't find anything that might point to the possiblity it could have osbestos in it or completely rule it out but the company that made it did use asbestos in alot of other products. So I guess it's better safe then dead... looking for a lab that's close.
Thanks guys.
