What is kaowool?

Recommended Posts

I think about makeing a gas fueled forge, and best insulation material seems to be kaowool. For a moment tought it was glass fiber pad, like the oven in a kitchen has. But I burned fiberglass the other day. So it is a simple question: What the hll kaowool is?

Many thanks.

Another point we're missing here is that Kaowool is a brand name of the ceramic or kaolin (or what ever it is) blanket refractory material. I don't know how many brands there are but another popular one that is actually available in my area (Omaha Ne) is Inswool. At least I think its the same as Kaowool, but less expensive :)

Just use your computer and Google Thermal Ceramics. They make all sorts of high temp insulation for stoves, chimneys, etc., such as Super Wool and Kaowool. FYI, their tech support people are among the most snidely and totally unhelpful people I have dealt with in a long lifetime, refused to answer the simplest questions re: a wodstove chimney problem I was working on last year. I guess they are scared to death of liability. Perhaps if you are really polite they will deign to tell you who might sell you some Kaowool. Or, if you just Google Kaowool, you can bypass these jerks and will find leads to scads of dealers. There are. by the way, other solutions, similar products.

But you need to handle it like fiberglas- it will do the pokey-itchy thing to you. I have been using some lately and I use some tyvek coveralls with elastic wrists and nitrile heavy duty(still good tactile) gloves. I have been cutting it outside and in open so wind(we have had a bit doncha know,) blows airborne away- I am up wind. I will likely pick up a few decent masks for when there is no wind. I sure like the way it sticks to metal with ITC stuff and toughens up well with the ITC 100. I have the #8 2600* stuff. I got 8square feet. It is easy to poke through when handling but it is like cotton candy in texture and you can pull off a scrap and fill the hole and it just blends in well- that miracle ITC 100- I am eager to get the 200 series stuff- I am fabricating a forge with my "revolutionary" HA-HA burner arrangement- some of you may find it interesting- it will offer a kind of flexibility not usually seen in gas forges. Really- might be the only clever thing I have come up with lately.mike

Hi Vic,
there is another material,which came from French spaceprogam(i think) and is called
Sibral-my gas forges are full of it,it`s perfect insulation,lightweight and they are selling it
in sheets,it looks kinda like cotton.
