Refractory thin board KAOCLAD

Price: on request

Kaoclad is the improved version of Kaowool Moist Felt, made from the highest quality spun fibre blanket with an inorganic hardening agent. It has excellent handling characteristics, both wet and dry. Kaoclad refractory sheet is supplied, packed in sealed polythene bags, as moist sheets that can be moulded to follow a curved or angled profile. After drying, (preferably between 60 0C and 90 0C), it provides strong, rigid yet lightweight insulation with texture and properties similar to Kaowool Inorganic Vacuum Formed Board. In the moist state, Kaoclad has a shelf life of up to 6 months, provided that the bags remain sealed and are maintained at temperatures within the range 10 0C to 50 0C. However, it is important to protect the material against frost.

moist impregnated mouldable sheets.

Classification temperature:
1260 grade - 1260 0C
1400 grade - 1400 0C
The maximum use temperature depends upon the application. In case of doubt, refer to your local Morgan Thermal Ceramics distributor for advice.

• good wet strength facilitates shaping and installation;
• after drying, provides lightweight but strong and abrasion resistant protection to soft substrate insulation;
• very resistant to thermal shock;
• low thermal conductivity - matches that of Blanket;
• can be used to make simple rigid shapes;
• sheet size 915mm x 610mm fits standard Blanket stud pattern.

•The main use of Kaoclad is as a protective hot face layer covering soft substrate fibre and other products, and where a contoured profile is required.
• Furnace buildings - hot face lining in furnaces, heaters and ductwork (when gas flow rate and particle erosion is too high for blanket), blast furnace tuyeres and element hanger anchor protection).
• Ferrous and non-Ferrous - lining ladles, launders and distribution boxes.
• Power Generation - insulation of steam turbines and ancillary plant (in conjunction with blanket).
• General - combustion chamber insulation repairs to refractory linings of steam-raising boilers, recuperator linings, pipe insulation and all areas where self-supporting thermal protection is required.

Availability and packaging:
Kaoclad 1260 and 1400 grades are normally supplied in standard sheets of 915mm x 610mm, in the following thicknesses. They are rolled and sealed in plastic bags, then packed in cardboard cartons.

Standard thickness (mm)

Packaging quantity per carton









Note: Due to the product’s inherently compressible nature, Kaoclad thicknesses once installed may be around 20% less than nominal.
In order to suit the previous Moist Felt stud pattern, Kaoclad can be supplied on request in sheets of 500mm x 1000mm and in the same range of thicknesses.
