Kaowool™ RT - 2,300°F / 1,260°C.
Kaowool is the original asbestos replacement material invented by Babcock and Wilcox.
Inswool is a similar competing product.
In blanket form Kaowool is commonly used to insulate high temperature furnaces, and to build forges and kilns.
The great advantage of Kaowool over other refractories is its very low density and ease of handling.
The density of Kaowool is approximately the same a dense fiber glass blanket and less than balsa wood.
The blanket is easy to cut with scissors or a knife making it possible to cut accurate shapes.
This ease of handling quickly offsets the cost difference compared to castable or refractory brick while providing a much higher insulating value.
Kaowool is commonly used to construct blacksmiths' forges and is often left uncoated.
However, Kaowool should be coated with a hard refractory to protect it from physical damage and creating airborne refractory dust.
ITC-100 is commonly used but is not 100% resistant to poking with sharp objects.
A coating of refractory cement or patching compound such as ITC-200 is recommended in hard use areas followed by a coating of
ITC-100.
Kaowool RT blanket comes in cartons of 50 square feet of 1" thick 24" wide rolled material, and
75 Square feet of 1/2" thick 24" wide material.
We sell cut lengths starting at one foot (two square feet), partial cartons and full cartons.
NEW! All full cases of Kaowool will be shipped by UPS only.
All broken (cut to length) amounts less than 25 feet will be shipped by US mail. DO NOT select UPS for these amounts.
Weight reported on the invoice is shipping weight including UPS oversize allowance for cases.
