Consideration should be made for fire retardancy of the material. The material is manufactured in blanket or rigid form. Thermal shock resistance is high. The material is noncombustible. The use and design of refractory range materials is an engineering art in its own right and is not treated fully in this manual, although some refractory products can be installed using application methods illustrated here.
Insulation values are moderate.
Cements may be applied to high temperature surfaces. Finishing cements or one-coat cements are used in the lower intermediate range and as a finish to other insulation applications. Check each manufacturer for shrinkage and adhesion properties.
