Strange "insulation" material

Strange "insulation" material

PostBy: markleo On: Mon Nov 24, 2008 12:13 am

Hey gang...

I am ripping out the walls in two rooms - literally - as part of a remodel, and when I removed some of the old trim above a door, a silicate-like, fine material with the consistency of sand came spilling out. It came from the wall cavity above the room I am remodeling, falling out as I removed the trim. I would say enough came out of the wall to fill a couple of 5 ga. pails. Is this some kind of insulation material? The house is 120 yrs. old. I know that the material is probably newer than that as they did not use any insulation back then, and I know the house has had some additions/remodeling done in the last 60 or so years.

I am partly concerned that it may contain asbestos particles. It looks like sand with glittery gold particles in it.

:?: Any guesses? :?: I'll try to get a pic of it and post.

Thanks,

Mark

It is probably vermiculite.

vermiculite mostlikely
my dad insulated his attic with it in the early 70's......all he could get from the lumber yard after the arabs cut the oil supply

Yup, the house I grew up in had vermiculite. It looks like rabbit food, but can break down into sand like dust complete with gold flakes. I guess a few patches had a small amount of asbestos contamination. This is how I took the story: Most is safe and the little bit that's not is no worry for one time contact I. If you worked in the factory in the one town that had the contamination and worked threre for 7,000 years then you may have an issue.

Either that or termite droppings. Seriously, a word about insulation. I ripped out the wallboard in a corner room in my house.Than i looked for the best insulation and decided to go with blown in foam. I haven't had the chance or money to run the heating system in that room yet.I gotta tell ya it is now the warmest room in the house.this foam is the best insulation out on the market.If you have the walls open i strongly advise you to go with the foam this stuff is unbelievable i think i could heat that room with a candle. Its bit pricey on the front end but it will pay for itself in spades.
Come April or may I'm going to do the rest of the house.Not so much because its great stuff i had that plan from the beginning.I just ran out of money last summer.I will never use a credit card again. EVER

Tugcapt.... if you do that to every wall you should give thought to an air to air heat exchanger. You might make your place so tight you'll have moisture issues or lack of air for vents & coal stoves.

Naw,
Just leave the old windows in. :shock:
DON

And they say that condesation isn't a problem either because it's "glued" to the sheathing.
Good stuff so far !

One more thing I was thinking about.How about if they made drywall with reflective coating on the back to put over that foam.I know to much time on my hands.

Hey Fred
Condinsation is not a prob with foam the space between the sheating and the wallboard is air tight.But,there may be a prob with my water heater which is on demand hot water ,my stoker and my oil furnace.although the oil hasn't been turned on in two years.
The thing is i'm doing this projet in steps.As in pay as i go.You have brought up another consideration.After the foam and new wallboard I think a check with the HVAC guy will be in order. Thanks (i think lol)

I've been getting estimates on closed-cell foam & the cheapest guy wants $6,000 just for the upstairs (walls & ceiling right to the peak)!!! :eek2: :eek2: :fear: And remember, my house is NOT that big! This is going 4.5" thick on ceiling & about 3" on walls.

There are 2 types of foam: Closed-cell & open-cell. Open-cell foam is the same as fiberglass as far as insulating properties (R-3.2) & is NOT a moisture barrier or an air barrier. It's soft, while closed-cell hardens like a brick.

I've been researching the stuff for the last 6 months. It has an R value of 6.7 - 7 per inch!! Double regular fiberglass. It's the only way I can insulate this place decently -- it kills 5 birds with one stone: fixes my moisture problems, insulates, stops air leaks, increases structural strength, & deadens sound. Just the fact that it stops air alone would make a HUGE difference in my house!

Maybe I can quit my job & build birdhouses......then attach them to houses, & charge $6K? :idea: Hmmmmmm.... :gee:

Believe it or not, it could be sand. Some old homes did use sand poured in from the top of the wall for insulation back in the old days
