I found this "fiberboard" behind the paneling in a house (built in 1943) I'm
going to flip. It's 1/2" thick and looks like 4' X 8' sheets. It seems they
panted it and wallpapered it and it has some sort of tar paper between it
and the studs. They were using it instead of drywall/plaster. It reminds
me of boards they used to use when I was a kid to stick thumb tacks into as
a cheaper alternative to cork. It has the strength of acoustic ceiling
tiles. Is there a name for it?

Looks like Celotex (a brand name for such a product). A quick Google
search shows how the company went bankrupt after asbestos lawsuits.

That's reassuring; growing up in the 60s, I remember that stuff being
*everywhere*; wall panels, bulletin boards, etc.

I'm not disputing what you're saying, but this stuff sure looks like a

Another very common material that fits the description is Homasote. It
was used a lot in barns and farmhouses, especially, because it was
very inexpensive and easy to work with. I've seen it used in exteriors
of barns, as well as home interiors. They have been making panels out
of recycled cardboard & paper longer than anybody. They are still in
business.

Don't forget Beaverboard. Here's a neat page-

[shows a bunch of different wall covers.]

Has a link to a page covering Homasote and 'other board'.

In the 70s it was common to put those 'exterior' sheathings under that
accursed wood paneling for its insulation qualities.

Looking at that link, it looks more like Homasote than the Celotex. The
Celotex doesn't seem to be exactly homogenous, like it has bits of longer
dark fibers running through it.

The whole reason I asked this question is that I want to ask the building
dept. if I can drywall over this stuff, because after I pulled off 2 layers
of paneling I found the fiberboard and then it seems they have already blown
in insulation. I don't see a reason to have to remove this stuff and
potentially disturb what appears to be blown in cellulose. It'll be cheaper
and more lung friendly just to throw up a vapor barrier and drywall. When I
talk to someone at the building dept. I didn't want to sound like I didn't
know what the stuff is called. At least someone should be fooled into
thinking I know what I'm talking about

I've noticed something like that under old commercial building flat
roofs. Someone mentioned exterior sheathing and that could be what
it is because it would seem to have some insulating value. I've had
to cut penetrations through some older flat roofs and stuff like that
always shows up in one or more layers.

Then just call it by its generic name fiberboard of which there were several
different brands made, sold and installed.

Yup. Homasote was/is often used for underlayment on flat roofs, and
does have some insulation value.

Probably a good idea, just to know for sure what it is. In many cases,
asbestos in things like this isn't considered a problem unless it gets
disturbed. Lots of old vinyl flooring had asbestos in it, but as long
as you kept a coat of wax on it to prevent the asbestos from exposure,
and becoming fryable, it was safe. The same goes for lead paint. If
there are coats of non-leaded paint over lead bearing paint, it is
considered safe.

In a 1943 house, you can safely assume there is asbetsos and lead
paint somewhere (or everywhere) in the building. Generally it does not
have to be removed, except in cases where demolition is taking place
that disturbs it or exposes it.


Ya know, we survived all that dangerous stuff and grew up and I
turned out OK 'cept for the drooling and the crazy eyes.

Why can't you drywall over it, you just need longer screws if you are
trying to get to the wall studs. And why do you need to talk to a
building dept just to repair walls? Unless you are moving/removing
walls, I can't see how sheetrocking calls for building permits.

Probably no permits needed on the sheetrock--- but if he is flipping
the house & will have the inspector wandering around anyway it is
smart to ask what he thinks. It puffs up the inspector- it gets an
opinion from a [hopefully] position of experience- and it covers his
butt if the new owners or their house inspector want to make an issue
of it.

If he simply sheetrocks over it, how'd they ever know????

And I certainly don't see any reason not to do so if there's reasonable
loose insulation behind it as I gather OP said.

Certainly it's no health menace to begin with what more once it's
covered w/ yet another layer.

The worst problem I'd foresee in doing that would be dealing w/ the
added thickness for doors and windows, etc. to trim out w/o a lot of
custom work which would tend to defeat general premise of "flipping".

When we bought the house at the beginning of Sept. the city required it to
be brought up to code. We couldn't even have anybody live there until all
the safety issues were taken care of. I got three pages of items from the
mechanical inspector and the electrical inspector said he'd have three pages
for me too unless I agreed to call in a contractor. He estimated it'd be
$3000 of work that needed to be done. I spent three weeks working on the
electrical myself before I called the contractor and got by with only a
$1000 bill. In among the items that needed to be done mechanically was to
"complete restoration work in laundry room and back bedroom." When we
started the laundry was bare frame and a plywood floor and the back bedroom
(where the fiberboard is) had a tile ceiling removed exposing more of the
fiberboard with glue spots on it where the 12 by 12 tiles were glued on.
Another requirement was that I trim in all 9 windows in the house. The new
vinyl widows the previous owners had installed that were smaller than the
old windows they had never been trimmed in and all the rough framing and
insulation was exposed around their perimeter. So, all of this was in plain
sight of all these inpectors that I'm getting to know by their first names.
I could go on for a day detailing the idiot things they lived with for
years in that house including the water pipes that were run through an
"unheated" attic, but were kept from bursting by leaving the access door to
the attic open and thus heating the attic. They were paying $2400/yr. for
gas in a 980 sq. ft. house rather than having the pipes moved . *rolling
eyes*

I talked to the inspector today and he'll let me drywall over the fiber
board as long as I install a vapor barrier. Any drywalling has to have a
rough framing/insulation inspection and a final inspection. I can't wait to
have them sign off on this house and that is when the real renovations will
commence.
