To analyze insulations with respect to their heat transfer behavior, a heat flow meter (HFM) or guarded hot plate (GHP) is normally used. These standardized measurement methods directly yield the thermal conductivity of insulation materials or the thermal resistance of multi-layer systems.
The thermal conductivity of refractory materials is determined on large samples with hot wire systems (TCT).
Using other thermoanalytical measurement techniques, the thermal stability or composition of insulating materials can be investigated. The curing behavior of organic binders used in insulation materials can also be characterized by means of DEA (Dielectric Analysis).
