Component-card (Individual material certification)
- Individual certification of the material and attribution to an insulation class (temperature class).
Indication of insulation class is universally valid, independent of the insulation system used.
System-Component-card (System certification)
- Combined certification of all components of a precisely defined insulation system.
- Thermally weaker components might be upgraded in combiniation with higher thermal class components.
- Indication of insulation class for an individual component (e.g. surface insulation material) is only valid for a single insulation system that must be precisely respected.
