SoliBlanket X-Grade

This is the cornerstone of our Refractory Ceramic Fiber range, combining Generation III Ultra Low Shot technology with a reliable 1260°C classification temperature and continuous operating capability up to 1150°C. Advanced spinning and optimized needling produce a higher fiber index, lower shot content, and a stronger fiber matrix. The result is improved tensile strength, enhanced resiliency after compression, and up to 36% better insulation performance in demanding high-temperature applications.

Product introduction

The industry long believed there was little room to improve traditional RCF blankets, until we proved otherwise. SoliBlanket™ X-grade is the cornerstone of our Refractory Ceramic Fiber range, combining proven alumina-silica chemistry with Generation III Ultra Low Shot technology. Advanced spinning methods produce a higher fiber index and significantly lower shot content than conventional RCF blankets.

By reducing non-fibrous shot particles, a greater proportion of the blanket consists of active insulating fibers. This increases thermal efficiency while supporting improved mechanLength (mm)ical performance across demanding industrial applications. Combined with optimized needling technology, the advanced fiber structure creates a denser, stronger, and more uniform fiber matrix. The resulting blanket delivers higher tensile strength, improved mechanical integrity, and greater resiliency after compression. These characteristics help maintain blanket performance during installation, maintenance activities, and repeated thermal cycling.

Independent testing has shown that these advancements deliver up to 36% better insulation performance than conventional RCF blankets. Reduced heat loss can contribute to improved energy efficiency and lower operating costs in high-temperature processes.

Available in densities from 64 kg/m³ to 160 kg/m³ and thicknesses from 6 mm to 50 mm, SoliBlanket™ X-grade offers flexibility across diverse industrial applications. With a classification temperature of 1260°C and continuous operating capability up to 1150°C, it is designed for demanding thermal environments. SoliBlanket™ X-grade sets a new benchmark for RCF blankets by combining superior insulation performance with enhanced mechanical durability.

Availability and packaging

Standard packaging

From our early start, we introduced a tight shrinkwrap packaging solution for SoliBlanket, being among the first to bring this concept to the market. Today, this approach is widely adopted, confirming its clear advantages.

Shrinkwrap packaging for blankets improves on-site efficiency and usability. Its compact form enables easier handling and smoother transport through confined spaces such as furnace manholes. It also reduces fiber dust exposure, offers better short-term weather resistance, and eliminates bulky packaging waste; resulting in faster and cleaner installation.

The concept also delivers significant logistics benefits. By optimizing pallet configuration, 24 rolls can be loaded instead of 20, allowing up to 25% more product per truck or container. This reduces transport costs and lowers the overall carbon footprint per delivered product.

Although plastic packaging has environmental considerations, we have minimized the impact by using film with recycled content. The result is a balanced solution combining operational efficiency with improved sustainability.

SoliBlanket is supplied in this optimized packaging wherever possible. On special request we still supply the carton boxes, and so do we supply our 6 mm rolls.

SoliBlanket is always supplied on ‘one-way’ pallets to optimize the required time for (un-)loading. A 40′ HC container loads a total of 520 rolls (21 pallets of 24 rolls + 1 pallet of 16 rolls) palletized and wrapped for easy and quick unloading.
