Cold & cryogenic systems

Below-ambient insulation is a different sport: the enemy is water vapour driving INTO the cold surface. Closed-cell materials (cellular glass, PIR, elastomeric) + vapour-barrier discipline.

Where it belongs

When this is the right system

Chilled water, refrigeration, LNG. Design rule: vapour barrier continuity beats lambda — one bad joint ices the line.

Standard: EN 14305 / ASTM C552 (cellular glass), C591 (PIR), C534 (FEF); CINI manual chapter on cold.
