High porosity refractory with low thermal conductivity used in order to reduce the rate of heat flow (heat losses) and thus to maximise heat conservation within the furnace. 

Options 

Bulk Fibre – Superior fire and heat resistance 1200 degrees Fahrenheit, fits quickly into grooves, slots and other hard to reach openings 

Mineral Wool – rated to 1,900 degree Farenheight, easily fabricated and installed, moisture repellent, non – corrosive, high compressive strength 

Ceramic Fiber – consists primarily of aluminum silicate, which includes fiber made from various polycrystalline fibers and molten glass. Ceramic fiber is a very useful and versatile substance used for containing or controlling high temperatures. A highly effective material that makes a lot of things possible for different manufacturing companies. <!–Various forms of ceramic fibers for different types of applications

Ceramic Board – are vacuum formed products that are made to resist high velocities. These products provide low heat loss and heat storage. Ideal for furnace linings, boiler ducts and stacks 

Ceramic Blanket – Ceramic fiber blanket is composed of long flexible, interwoven fibers manufactured by the “spin” process yielding a strong, lightweight, durable product. It is perfect for situations with direct exposure to flames. Available in soluble (2300), High purity Ceramic Fibre (2300), Zirconia (2600), Maftec/Polycrystalline Mullite(3000) 

Ceramic Paper – Paper is a lightweight refractory material processed from a blend of high purity alumina-silica wools. This product can be used for applications for continuous use to temperatures of 2300°F (1260°C). Paper has a good handling strength, low thermal conductivity and low shrinkage. It contains an organic binder which makes it flexible and reduces off-gassing and odor during use. The paper has highly uniform consistency due to its controlled basis weight and thickness. This product is ideal for gaskets and seals. Paper is durable and can be easily cut. Its flexibility allows it to be wrapped or rolled to fit around most configurations. 

Rope – As a rope, ceramic fiber is used for support or to attach various heat resistant structures. They can be used as winding for high-temperature pipes, expansion joints as well as heated steel junctions. Ceramic rope can withstand high temperatures up to 2300°F / 1260°C. In addition to having low thermal conductivity, ceramic rope is also recognized for being lightweight, chemical resistant, and fire resistant. –>
