Product Description
Ceramic Fiber Fireplace Insulation Board
YinLian fireplace insulation board is rigid products made from ceramic fiber which are vacuuming formed with organic and inorganic binders, with or without mineral fillers. These are manufactured over a wide range of grades densities and hardness.
The board is featured with high temperature stability, low thermal conductivity, even density, and excellent resistance against thermal shock and chemical attack. They can be used as individual component attack. They can be used as individual component of furnace lining or as hard hot face layer as backup insulation.
Features of fireplace insulation board
1. Low thermal conductivity and low heat storage
2. Excellent thermal shock resistance
3. Resistance to most chemical attacks
4. Low sound transmission
5. Easy to cut, handle and install
6. Resist penetration by molten aluminum and other non ferrous metal
Applications of fireplace insulation board
1. Refractory lining for industrial furnace wall, roofs, doors, stacks etc
2. Combustion chamber liners, boilers and heaters
3. Expansion joint board
4. Barrier against flame or heat
5. Heat insulation of high temperature and high heat equipment
6. Heat insulation, fireproof and sound insulation of aerospace, ship building industries
