What is Kaowool made of?

Kaowool is made from a blend of alumina, silica, and kaolin using a spinning process for tough construction. Engineered to last without losing strength, Kaowool is an incredible piece of technology that will keep your boiler system running strong.

Likewise, does Kaowool contain asbestos?

Kaowool is made from ceramic fiber. No asbestos involved.

Additionally, what is Rockwool made from? Characteristics of rock wool. Rockwool, a lightweight hydroponic substrate is made from spinning molten basaltic rock into fine fibers which are then formed into a range of cubes, blocks, growing slabs and granular products.

In this regard, is mineral wool safe to breathe?

The downside to mineral wool One is that mineral fibers can break off and become airborne; when we breathe those fibers in they can cause health problems. In the past there was some concern that mineral wool and fiberglass fibers might be carcinogenic, like asbestos.

Is Kaowool flammable?

Non flammable, No fire or explosion hazard exists. Packaging and surrounding materials may be combustible. Use extinguishing agent suitable for surrounding combustible materials.

What is millboard insulation?

Interface Performance Materials' millboard materials are strong, thin, dense boards with excellent insulating characteristics. They are made from ceramic fiber, clay, inert fillers and a small amount of organic and/or inorganic binders for increased handling strength.

Is ceramic wool dangerous?

Respiratory hazard from removal of ceramic fiber insulation from high temperature industrial furnaces. Although toxicity data to date have found these ceramic fibers to be innocuous, recent studies have shown the fibers to devitrify and undergo partial conversion to cristobalite when exposed to elevated temperatures.

How long does Kaowool last?

Normal shelf life of the Kaowool thermal ceramics rigidizer is twelve months in unopened containers that have been properly stored.

What is Satanite?

The Satanite is a refractory cement that insulates the surface of the wool, this keeping more of the heat in the chamber ( it does not reflect or absorb, just insulate). The ITC-100 is a highly heat reflective coating that greatly reduces the heat loss. My process is to use a 2" kaowool blanket.

How much Satanite do I need?

We generally recommend a basecoat of 1/4" of Satanite and then a topcoat of ITC-100. This provides a more robust coating with the added efficiency obtained from the use of ITC-100. Generally, for most forges, a five pound bag of Satanite and a half pint of ITC-100 is sufficient.

How do you make refractory cement?

How to do it:

Weigh the kaowool and break it up into a bucket.

Measure and add the refractory clay to the bucket. (

Add the water to the bucket.

Mix it.

Measure out the perlite and add it to the mixing tub. (

Add the clay mix to the mixing tub.

Mix it completely until there is no dry perlite.

What is ceramic fiber?

Ceramic fiber is a kind of fibrous lightweight refractories. It has the advantages of lightweight, high-temperature resistance, good thermal stability, low thermal conductivity, low specific heat, and mechanical vibration resistance.

How thick should refractory cement be?

between 40 mm and 200 mm

Can insulation cause cancer?

There is no evidence that fiberglass causes cancer in people. Animal studies have shown an increased risk of cancer when fiberglass fibers were implanted in the lung tissue of rats, but these studies are controversial because of how the fibers were implanted.

Is Rockwool cancerous?

The more common types of rockwool used as insulation are considered by the International Agency for Research on Cancer to be "not classifiable as carcinogenic in humans." Rockwool can cause skin irritation, although this condition is a temporary mechanical irritation, rather than a more serious chemical irritation.

Is Rockwool bad for your lungs?

Not only is rockwool unfriendly to the environment – it's also potentially harmful to your health. New blocks can contain a lot of dust and loose fibers that can get in your eyes, mouth, skin and lungs. If you're using rockwool, you should be using a mask, goggles and gloves when you work with it to protect yourself.

Does Gold Bond rock wool contain asbestos?

Rock wool is another name for mineral wool insulation. Industry leaders of rock wool products included Johns Manville and Gold Bond. The majority of these products did not contain asbestos, but some companies experimented with stitching asbestos and rock wool together.

Does Rockwool contain formaldehyde?

Standard ROCKWOOL products do currently use a phenol formaldehyde binder during production. ROCKWOOL also offers a no added formaldehyde product, AFB evo™, starting July 1st 2017.

Can mineral wool be recycled?

Once a building is to be refurbished or demolished, its insulation can be recycled. Mineral wool insulation can be easily and safely removed and either re-used in another building or reprocessed to make new insulation. An increasing proportion of stone wool insulation is recycled material in the form of briquettes.

Is all Rockwool fireproof?

ROCKWOOL Stone wool insulation is non-combustible and will slow the spread of fire in the construction, protecting lives and investment.

Is stone wool the same as mineral wool?

There are two types of mineral wool product: glass wool insulation and stone wool insulation. Stone wool is made from volcanic rock, typically basalt and an increasing proportion of recycled material in the form of briquettes. Mineral wool made from blast furnace slag (waste) is sometimes known as slag wool.

Does mineral wool absorb water?

However, when basic water absorption tests are performed on a standard mineral wool product, it absorbs water readily, and the absorbed water takes days to drain from the insulation. While it is wet, mineral wool insulation has reduced R-value (RSI)*, resulting in higher heat loss from the building.
