Our Superwool products are produced from specific alkaline earth-silicate raw materials, uniquely engineered for high temperature insulation applications. They offer low biopersistence, up to 20% lower thermal conductivity compared to refractory ceramic fiber (RCF) insulation and resistance to molten aluminum.
- Superwool Plus offers good low thermal conductivity and good thermal shock resistance.
- Superwool HT provides outstanding insulating properties at elevated temperatures.
- Superwool XTRA is specially processed to offer excellent performance in high-temperature applications. It provides excellent thermal insulation characteristics and exceptional handling properties, and is resistant to chemical attack.
Types of Superwool Products
Superwool high-temperature insulating fiber boards are well-suited for use as back-up insulation or installed as hot face application solutions ranging from furnace linings to burner surrounds to hot tops. They can be used as rigid, self-supporting insulation or can be manufactured into a flexible solution. Both formats provide an exceptional performance-to-weight ratio and are resistant to most chemical attacks. They also offer potential space savings of up to 50% thickness when replacing insulating firebricks and castables.
Superwool blanket products are lightweight and strong for easy installation, excellent heat storage capacity for effective energy savings, and good thermal shock resistance for use in difficult environments. They provide lower thermal conductivity compared to some RCF fiber materials. They can improve insulation performance by up to 20% and weight savings of up to 25%. They offer low biopersistence and can withstand temperatures from 2372°F to 2600°F.
Superwool-based papers can be used for thermal and acoustic insulation in applications such as heat shields and airbags. Superwool paper is resistant to chemical attack and is non-wetting to molten aluminum. It is the only low biopersistent fiber available with a classification temperature of 2372°F.
Superwool Pyro-Block modules are ideal for fast installation in industrial heaters, boilers and furnaces. Superwool offers an exceptional performance-to-weight ratio and is resistant to chemical attack. It has low biopersistence and can withstand temperatures from 2372°F to 2600°F.
Superwool-based caulks are used to repair ovens, furnaces and process equipment, fill cracks and gaps in refractory linings, and to enhance or repair thermal insulation in refractory applications. They also provide protection against chemical attack from alkalis, iron oxide and air and moisture infiltration. These caulks offer low thermal conductivity and heat storage capacity for effective energy savings. They are also durable and are resistant to thermal shock and erosion.
- Low biopersistence
- Low thermal conductivity
- Excellent thermal shock resistance
- Minimal linear shrinkage up to its classification temperature
- Up to 30% more fibers, which provide efficient prevention of heat transfer and excellent strength
- Potential for material weight savings (less insulation is needed to achieve the same level of thermal protection)
