Durablanket® is a high-performance needled ceramic fibre blanket engineered to provide reliable thermal insulation, exceptional handling strength and long-term durability in demanding industrial environments. Manufactured from spun ceramic fibres using a unique cross-locking process, it delivers outstanding resilience while maintaining excellent thermal performance at elevated temperatures.
Lightweight and flexible, Durablanket combines low thermal conductivity with excellent thermal stability, helping improve energy efficiency while reducing heat loss across a wide range of industrial processes. Its robust fibre structure resists tearing during installation and handling, making it an ideal solution for applications where mechanical durability is as important as thermal performance.
Designed for long service life and dependable operation, Durablanket is widely used throughout furnaces, kilns, boilers, process heaters and thermal processing equipment where effective heat containment and insulation are essential.
Durablanket combines excellent thermal insulation performance with superior handling strength, making it one of the most versatile ceramic fibre blanket solutions available for industrial applications.
