Ceramic Insulation Blanket – CCEWOOL®

In long-term operation of glass melting furnaces, the furnace roof is constantly exposed to high-temperature radiation, hot gas flow erosion, and structural thermal cycling. It is one of the most vulnerable areas for insulation degradation and heat loss. Traditional insulation structures, such as composite bricks and standard fiber products, often suffer from compression, fiber shedding, and heat penetration, leading to reduced thermal efficiency, increased energy consumption, and frequent maintenance.

To address the challenges of curved roof geometry and long-term thermal cycling, CCEWOOL® ceramic insulation blanket 2300 offers outstanding flexibility and thermal stability. Produced with ultra-long fibers and a double-sided needling process, the blanket features superior conformability and tensile strength. Even under continuous operation above 1260°C, it resists powdering, sagging, and delamination.

Improved Thermal Efficiency and Extended Maintenance Cycles – Real Results from the Field

In actual use, a customer in Spain applied CCEWOOL® ceramic insulation blanket to the furnace roof of their glass melting unit. After replacing the original materials, the customer reported a significant reduction in heat loss, more uniform internal temperatures, and a 12% improvement in thermal efficiency. The insulation structure remained stable with no visible deformation, and the maintenance cycle extended from 9 months to over 15 months—resulting in substantial savings in operating and repair costs.

20 Years of Insulation Expertise – Driving Innovation for Furnace Roof Applications

With over two decades of experience in high-temperature insulation, CCEWOOL® continues to refine its ceramic insulation blanket series. By improving raw material purity and optimizing fiber structure, we have achieved a balance between flexibility and heat resistance tailored for industrial needs. For roof areas exposed to extreme heat flow, we offer not only enhanced fiber strength but also customized composite layer solutions—helping customers extend lining life and improve overall energy performance.
