Vintage Loose-fill attic Insulation

Recommended Posts

I see this insulation, now and then in the attics of old homes. This home is 1942. I've alway assumed it's cellulose, but would hate to be wrong. Anyone got a bead on this stuff? I know it's not vermiculite or fiberglass. I'd like to finally nail this one down for my future reports. [:-magnify

Thanks Les. I've always wondered - odd looking stuff. Now I can add it to my drop-down menu for insulations.

But, that has me wondering, is it flammable, Les? Or, has it been treated with some lovely, now known to be nuclear or carcinegenic flame retardant meterial?

Nearly all the materials I have tested have had traces of borate. Some I have "Jim Katen field tested" actually did support combustion. Either not treated or leached out.

Is it correct then to call it "cellulose"? I think so.

The reddish-brown shredded wood, I call "shredded wood", as it appears to be less thoroughly processed than what I've been calling "cellulose".

I sometimes see "sawdust" that looks like it came straight from the mill. That stuff will burn, I'm sure.

What I call "Rock wool" would be predominantly mineral based, and looks like gray fiberglass.

But, Balsam Wool has such a nice ring to it -kinda like the difference between a statin and Lipitor. ;-)

Yes, John has Rockwool right. It's rather like shredded angel hair that has a lot of gray in it, as if it's been used to polish silver. It always looks exactly the same.

But, then I realize that you'd have to be an old fart to know what angel hair is. I could go on to explain how it was the fine white stuff that was on the angel on the tip top of your Christmas tree when you were a kid, but still you'd have to be an old fart. So, I may not be able to help you, Mark, unless of course you already happen to be an old fart. [:-tophat]

Anybody put the fake snow on Christmas trees in the 50s and 60s? It was a mix of mica and asbestos!

Nice!

I'm doomed...

As far as my drop-down menu goes, maybe I could have a statement that says, "Your guess is as good as mine, but whatever it is, there's not enough of it. And, since it probably contains something bad for you, it's best to add more insulation." [:D]

That can be a decaying wood. It will always depend on the texture. Better ask an expert about it so that you will be sure.

I didn't gather it from an obscure location. It was installed uniformly throughout the attic as an insulation.

If an inspector can't tell the difference between insulation and, "a decaying wood" then he best find another job.

I was thinking the same thing. Sounds like someone that likes to cry wolf and get people all excited due to lack of knowledge.

Well, for a moment Les had me thinking I was in possession of a title. Everyone else has a title. I'll live.

Mr Decaying Wood deleted his post and went away. You have done neither.

How about "Swamp Thing" for a title? [:)]
