For glass manufacturers facing rising energy costs and tighter emissions regulations, upgrading furnace insulation isn’t just smart—it’s essential. At Zhengzhou Rongsheng Refractories, we’ve helped over 70 global clients achieve consistent energy savings of 30–45% using our custom-made aluminum bubble bricks (alumina hollow sphere bricks).
“After installing Rongsheng’s aluminum bubble bricks in our melting tank, our gas consumption dropped by 37% within three months—without any change in production output.”

Traditional refractory materials often fail under extreme thermal stress or suffer from high heat loss. Our proprietary manufacturing process combines high-purity bauxite powder with hollow alumina spheres, sintered at temperatures up to 1800°C. This results in:
| Material Type | Max Temp (°C) | Thermal Conductivity (W/m·K) | Avg. Energy Savings |
|---|---|---|---|
| Standard Firebrick | 1500 | ~0.8 | 10–15% |
| Aluminum Bubble Brick (Rongsheng) | 1800 | ~0.15 | 30–45% |
Every glass plant has unique operating conditions—from batch types to kiln design and local climate. With 20 years of experience serving clients across Europe, the Middle East, and Asia, Rongsheng offers tailored solutions based on:
We don’t just sell products—we build long-term partnerships that deliver measurable ROI. Whether you’re running a small artisanal studio or a large-scale production line, our team ensures seamless integration and real-world efficiency gains.
