The ceramics and kiln industry encompasses some of the broadest temperature ranges in industrial thermal processing — from 900°C for red clay tile firing to over 1600°C for advanced technical ceramics. Tunnel kilns, shuttle kilns, bell kilns, and roller hearth kilns all demand refractory linings that provide thermal uniformity, rapid thermal response, and excellent insulation to minimize fuel consumption.
Firebrics lightweight insulating bricks (JM series, IFB series) are the core product for ceramic kiln backup insulation and kiln furniture. Our products are used in tile factories across Vietnam, porcelain manufacturers in Southeast Asia, and technical ceramics producers globally, helping customers reduce energy costs by up to 25% compared with traditional dense brick linings.
Key Application Zones
Side walls, crown, and hot face lining for continuous tunnel kilns — lightweight JM28/JM30 bricks provide fast heat-up and low energy storage for efficient thermal cycling.
Batch kilns require refractories with low heat storage capacity for rapid temperature swings — lightweight insulating bricks minimize cool-down time between cycles.
Kiln car tops and saggar support beams demand high alumina or silicon carbide bricks with excellent creep resistance under load at peak firing temperatures.
Thin wall construction with maximum insulation for tile and sanitaryware firing — our lightweight modules and castable panels enable high-speed continuous firing lines.
