Product Description

Ceramic Fiber Blanket Kiln Backup Insulation High Temperature Alumina Silicate Needled Roll

Product Description

Ceramic Fiber Blanket is a needled alumina-silicate insulation roll used widely as backup insulation in ceramic and refractory kilns. Made from high-purity fibers interlocked without organic binders, it keeps its strength and shape where glued products would weaken at high temperature.

As a backup layer behind refractory linings, the blanket reduces shell temperature and heat loss while cushioning the brickwork against thermal movement. Its fibrous structure absorbs thermal stress, so it resists cracking and spalling through repeated firing cycles.

The blanket is lightweight, non-combustible and chemically stable, and can be cut and layered to fit curved kiln walls and crowns. It is a dependable, low-maintenance insulation solution for tunnel kilns, shuttle kilns and roller hearth kilns.

Product Features

High Temperature Resistance – Rated for continuous service near 1000°C with classification temperature up to 1260°C.

Kiln Backup Insulation – Reduces shell temperature and heat loss behind refractory linings in ceramic and refractory kilns.

Needled Ceramic Fiber Roll – Interlocked fibers cushion brickwork against thermal movement and resist cracking.

Excellent Thermal Shock Resistance – Handles repeated firing cycles without losing structural integrity.

Lightweight and Flexible – Easy to cut and layer over curved kiln walls and crowns.
