Ceramic Blankets

A ceramic fibre blanket is a soft, flexible mat of long ceramic fibres, needled together so it holds its shape without a binder. It is one of the most useful insulation materials for anything hot: it is light, easy to cut and fit, and it keeps a lot of heat in.

Main features

• Light and flexible. It bends around curves, pipes and odd shapes.
• Low heat loss. It saves fuel and keeps the outside of the furnace cooler and safer.
• Low heat storage. A light lining heats and cools fast, which saves time and energy in batch furnaces.
• Strong against thermal shock. It does not crack when heated or cooled fast.
• No binder. No smoke or smell on first heating.

Grades and sizes

Grade	Classification temperature (about)
Standard	1,260 °C
High purity	1,260 °C, for cleaner, longer use
Zirconia-containing	1,430 °C

Common density is 96 or 128 kg/m³ (a higher density means a stronger blanket that handles gas flow better). Common thicknesses are 13, 25 and 50 mm, sold in rolls.

Where it is used

• Furnace and kiln linings, in layers or as folded modules
• Furnace doors and seals
• Insulation of pipes, boilers and turbines
• Fire protection and heat shields
• Repair work on hot linings

Tips for use

• Choose a grade at least 100–150 °C above your working temperature.
• In hot gas flow, a higher density or a board on the hot face lasts longer.
• Wear gloves, long sleeves and a dust mask when cutting.
