DALFRATHERM® Felts

High temperature insulation felt

The DALFRATHERM® range of high temperature insulation felts are soft vacuum-formed felts and boards, based on alkaline earth silicate (AES) wool or aluminium silicate wool. These lightweight, homogeneous insulation materials are characterised by a high temperature resistance, low thermal conductivity, and high resistance to thermal shock and chemicals.

The DALFRATHERM® range of felts is available different types with different dimensions, densities and classification temperatures up to 1430 °C. They are developed to reduce heat loss and overall energy consumption, and to meet the most stringent requirements for the final application.
