Cork insulation

[sspradling]

Has anyone seen loose fill cork used as insulation in at attic? Yesterday's morining inspection was a 60 year old with what appears to be cork, in pieces from pea sized to almost baseball sized. Having never seen this before, I performed a Neuman test over the bathroom sink, and this stuff is definatley flammable.
I know a picture would help. I'll try that later.

Granulated and agglomerated cork as insulation was mostly an industrial product in 40's, 50's, and early 60's.

They also say that cork is almost completely fire resistant. Maybe you're not dealing with cork?

I believe a true Neuman test would have entailed inhaling.......

From somewhere within that same URL:

"The manufacturing of cork products for the building industry produces an important waste product, cork powder. This powder is commonly burned to produce steam and/or energy which is used in the factories themselves, given the high energy content of this material."

Obviously, cork is flamable. When I was young we used to burn cork to make a charcoal product for art usage.

I am posting these pics for Sturart. Does anyone recognize this insulation?

I'm not sure wtf a neuman test is

But a true Neumann test would require you to take that insulation back to your office first b4 lighting.... If this were the members only secion I would tell you what I would do with the fumes.

Tony, I think the "Neuman test" refers to a post you made a few days ago about burning something in a sink to test it.

[Michael Larson]

What, nobody has an opinion of this stuff?

Let's help Stuart out if you have seen this type of insulation posted in post #8.

It looks odd to me. And I also note the buried K&T

[sspradling]

Michael,
Thanks for your help posting the photo. I did note the k&t.
Jae, you are right.
Tony, no offense meant. I'll spell your last name right next time.

Your welcome.
Please don't tell Jae he's right too often or he will have to buy a new hat.

Stu,

Did that insulation feel like cork?

It is some strange looking stuff.
From the pics it looks like a mixture of materials.

First and foremost, gongrats Tony for a test being named after yewwww. I recall testing a fallen stand of eucalyptus trees once as a youth with bottle rockets.

Michael it looks like cork to me, from here.

Hey, Maude--come look at this...you ain't gonna believe it.

Gotta print this thing out and send it to my mother-in-law (she'll never believe it, neither).
