Why Airtightness Matters in Cold Storage Facilities

In cold storage design and operation, controlled air leakage is not optional—it’s critical. Uncontrolled infiltration of warm, humid air into refrigerated spaces drives:
  • Excessive refrigeration loads
  • Moisture ingress, frost buildup & evaporator defrost cycles
  • Higher energy operating costs
  • Safety and WHS hazards on floors and racks
  • Reduced product safety and shelf life
Every gap in insulated sandwich panels, dock seals or service penetrations becomes a pathway for “latent heat gain,” forcing your refrigeration plant to work harder to remove both heat and moisture. Aerotight testing identifies and eliminates these inefficiencies before they can impact your bottom line.

Airtightness Standards & Australian Regulation

Cold storage facilities in Australia are increasingly required to demonstrate compliance with building performance standards and energy efficiency regulations.

National Construction Code (NCC) & Section J

Under NCC Section J verification methods (e.g., JV4 and related air permeability performance paths), building envelopes must meet specified airtightness targets measured in m³/h per m² @ 50 Pa. Aerotight provides certified testing and reporting for Class 7b and Class 8 refrigerated buildings in compliance with NCC requirements.

ISO & International Testing Methods

Aerotight conducts testing aligned with internationally recognised protocols, such as:

  • ASTM E1827 – Air leakage of buildings using blower door tests
  • ATTMA Level 3 large‑scale testing standards

  • Applicable elements of CIBSE TM 2:3 and related performance measurement methodologies

These standards ensure your facility’s airtightness measurements are accurate, reproducible and defendable in regulatory, rating or investor contexts.

Green Star Design & As‑Built points

Airtightness performance can contribute to Green Star Design & As‑Built points, helping cold storage projects demonstrate sustainability leadership and lower life‑cycle energy use. Aerotight has led industry firsts in navigating air permeability testing for Green Star projects.

Aerotight Services for Cold Storage Integrity

We tailor airtightness solutions to the unique thermal challenges of refrigerated environments:

Whole‑Facility Pressure Differential & Blower Door Testing

Using high‑capacity systems designed for large volumes (>100,000 m³), we measure air leakage across your entire conditioned space or defined zones. Whether in planning, construction or retrofit, Aerotight tests verify compliance and performance.

Panel Joint & T‑Bar Diagnostics

Sandwich panel interfaces are the most common source of leakage. Our diagnostics use:

  • Non‑toxic smoke tracing
  • High‑resolution thermal imaging
  • Targeted pressure testing

This allows your team to pinpoint breaches with precision and remediate efficiently.

Loading Dock & Rapid‑Rise Door Airtightness Audits

High‑traffic door seals and dock levellers are thermal liability points. Aerotight audits ensure seals maintain continuous thermal breaks, reducing infiltration during peak operations.

Chimney Effect & Ridge Vent Analysis

Tall storage spaces can experience vertical pressure differentials that draw warm air in through roof penetrations. Our testing quantifies this “chimney effect,” enabling targeted corrective measures.

Non‑Disruptive ‘In‑Situ’ Programmes

To minimise impact on your 24/7 operations, we offer phased, low‑traffic and partial‑zone testing strategies that fit within your operational schedule.

Frequently Asked Questions

In Australia’s humid climate, air leakage is the primary cause of moisture ingress. When warm, moist air enters a freezer, it flash-freezes on surfaces and evaporator coils. Aerotight provides the precision testing needed to stop this "latent heat gain," protecting your facility from the ice buildup that cripples operational efficiency and threatens food safety.

Air leaks act like a "vacuum" for heat. Every cubic meter of warm air that enters must be cooled to sub-zero temperatures. More importantly, your refrigeration plant must work overtime to remove the moisture from that air. By sealing the envelope and verifying it with an Aerotight audit, facilities often see a 20–30% reduction in total refrigeration energy spend.

Yes. Moisture migrates to the coldest point in the room - the evaporator. Excessive ice buildup forces the system into frequent, energy-intensive "defrost cycles." Aerotight identifies the specific panel joints and service penetrations allowing moisture ingress, ensuring your coils stay clear and your heat exchange remains efficient.

In tall cold stores, heavy cold air sinks and leaks out of the bottom (usually through loading dock seals), creating a vacuum that sucks warm, humid air in through the roof or ridge vents. Aerotight’s ATTMA Level 3 testing quantifies this "Chimney Effect" and identifies the high-level leaks that are often invisible but cause the most damage.

We use a combination of high-resolution thermal imaging and non-toxic smoke testing. Thermal imaging identifies "cold bridges" where insulation is failing, while smoke testing visualizes the exact path air takes through panel joins, T-bars, and corner flashings. This allows for surgical repairs without replacing entire wall sections.

Yes. Under NCC 2022 Section J, new refrigerated warehouses (Class 7b or 8) must demonstrate compliance with air permeability targets, typically 5 m3/h.m2 or 10 m3/h.m2. Aerotight provides the certified "as-built" testing required for building handover and Occupancy Permit approval.

Absolutely. Loading docks and rapid-rise doors are the most vulnerable points in a logistics hub. Even a small gap in a dock leveller seal can allow massive amounts of heat ingress. Aerotight audits these "high-traffic" zones to ensure your thermal breaks are maintained even during peak operational hours.

We use high-output blower door arrays and "zoned testing" protocols. For large-scale logistics hubs, we can often perform testing during "low-traffic" shifts or in specific chambers to minimize disruption to your 24/7 operations. Our ATTMA Level 3 accreditation means we have the scale to test the largest DCs in Australia.

Yes. When humid air leaks into a -20°C environment, it creates "snow" on racks and ice patches on floors. This is a major WHS risk for forklifts and personnel. By identifying and sealing the envelope breaches with Aerotight, you eliminate the source of the moisture, creating a safer, dryer, and more predictable work environment.

Most facilities see a full return on investment within 12 to 18 months through energy savings alone. When you factor in reduced wear-and-tear on compressors and fewer manual de-icing labor hours, the ROI is even faster. Aerotight provides the technical data you need to justify the maintenance spend to your board or facility owner.
