Typical applications

High temperature insulation wool is an ultra-lightweight insulation material that, due to its properties, provides highly efficient thermal insulation for industrial furnace construction applications.

RATH has been manufacturing products such as wool, mats, stampings, and modules for more than 25 years now. In application, temperatures up to 1650°C can be insulated.

Due to the low thermal conductivity, the energy input can be significantly reduced with infeed concepts using modules made of high-temperature wool. This reduces CO2 emissions as well as costs.
