Why It Matters
Extreme-Temperature Performance
Firebrick, castables, and ceramic fibre systems rated for continuous service up to 1400°C and beyond — specified to your process conditions.
Lower Fuel & Energy Costs
Reduced thermal mass and optimised lining design cut heat storage and fuel consumption while extending equipment service life.
Compliance & Safety
Installations engineered for safe operation, minimal downtime, and long service intervals — backed by IRC industrial refractory heritage.
What We Do
Full scope of supply and installation for refractory & high-temperature insulation.
| Material | Temperature Rating | Typical Use |
|---|---|---|
| Firebrick / Insulating Bricks | Up to 1400°C+ | Kilns, furnaces, kiln cars |
| Ceramic Fibre & Modules | Up to 1300°C | Low-thermal-mass linings |
| Refractory Castables | Up to 1400°C+ | Complex shapes, burner blocks |
| Calcium Silicate Board | Up to 1000°C | Boilers, ducts, back-up insulation |
| Vermiculite | Up to 1100°C | Insulation fills, expansion joints |
