Cold & frozen storage
Air barriers for cold and frozen storage
When a cold-room door opens, air masses with different temperatures and humidity meet. A correctly designed air barrier can reduce the exchange while goods continue to move between zones.

Energy first · Cold & frozen storage
Reduce energy losses. Assess heating and cooling demand.
Our priority is energy efficiency at open industrial doors: retaining heat in heated halls and limiting heat ingress into chilled and frozen areas. A tailored air barrier can reduce air exchange while keeping goods moving.
We assess opening times, temperatures, wind and building pressure. Draughts, hygiene and emissions are additional requirements.

Warmer, more humid air from an adjacent area can enter a cold or frozen room; cold air escapes in the opposite direction. Depending on the conditions, this can increase refrigeration demand and contribute to fog, condensation or ice near the door.
A directed air stream can reduce heat and moisture exchange while the door is open. Door dimensions, humidity, temperature differences, traffic and the interaction with existing doors and ventilation all matter. For frozen storage, we assess the freezer and the adjacent zone together: where moist air originates, how long the door remains open and where ice forms. This helps determine whether an air barrier is a suitable addition to the existing cold-room door.
Transitions with high demand
Frozen room and ante-room
Large temperature differences and moisture ingress during frequent goods movements.
Cold storage and loading
Repeated door openings in temperature-controlled distribution.
Internal climate zones
Routes between differently conditioned parts of a building.
Measure both sides of the doorway
Door dimensions alone are not enough for a cold-store design. Conditions on both sides and the actual opening pattern are essential.
- Temperatures and, where available, humidity in both zones
- Door size, opening duration and frequency
- Vehicle traffic and existing door equipment
- Observed fog, condensation or ice
