Product Benefits

Superwool is a versatile and high-performance insulation material that showcases exceptional properties that make it ideal across a wide range of applications including:

Superior Insulation Properties Superior Insulation Properties 

Superior Insulation Properties 

As an alkaline earth silicate (AES) fiber-based material, Superwool exhibits remarkable insulation properties, especially at elevated temperatures. Its unique composition ensures high thermal resistance, making it an excellent choice for applications requiring heat containment.

Low Thermal ConductivityLow Thermal Conductivity

Low Thermal Conductivity

Superwool boasts remarkably low thermal conductivity, allowing for effective thermal insulation in a wide range of environments. By reducing heat transfer, it helps maintain desired temperatures, resulting in energy efficiency and cost savings.

Safe-to-Use Alternative Safe-to-Use Alternative 

Safe-to-Use Alternative 

Superwool is a safe-to-use alternative to traditional insulation materials which may carry potential health risks. Unlike other fibrous materials, any Superwool fibers that may be inhaled are naturally removed by the body's processes, reducing health concerns for workers and end-users. 

High Classification TemperatureHigh Classification Temperature

High Classification Temperature

With its high classification temperature, Superwool can withstand extreme heat conditions without compromising its insulation properties. This makes it a reliable choice for high-temperature processes across various industries.

Low ShrinkageLow Shrinkage

Low Shrinkage

Minimal shrinkage even at high temperatures means that Superwool has dimensional stability and preserves the integrity of insulation over time. This property is essential for applications that demand long-term performance and reliability.
