SCROLL
In precision environments such as semiconductor fabrication, pharmaceutical production, medical device assembly, and biotech labs, airtightness isn’t just performance – it’s mission‑critical.
At Aerotight we compile an Aerotight Strategy for projects from concept through commissioning, ensuring that air leakage paths are quantified, understood, and resolved.
The NCC sets minimum performance standards for building energy efficiency and airtightness. Under Section J, building envelopes must achieve measurable envelope performance targets. Cleanrooms with high pressure differentials or controlled ventilation must address these requirements directly.
Aerotight Compliance: Our testing and reporting directly map to NCC / Section J metrics when applicable, providing documentation suitable for certification and regulatory submissions.
Cleanroom integrity often aligns with ISO standards such as:
Aerotight Testing employs ISO‑aligned methodologies and calibrated equipment to produce accurate, repeatable measurements you can trust.
Sustainability ratings like Green Star (GBCA) increasingly demand evidence of energy‑efficient design, including mechanical performance and envelope tightness. Airtight cleanrooms contribute to lower HVAC loads and overall building energy performance.
Our airtightness testing supports documentation for Green Star submissions and sustainability case studies.
Our specialised cleanroom testing services include:
Cleanrooms rely on precise pressure hierarchies (e.g., ISO 5 → ISO 7 zones). We verify that pressure boundaries hold under design conditions.
Our detailed reports support commissioning sign‑off and include: Test results with ISO referencing Graphs, charts, and leakage profiles Recommendations and corrective strategies
Not all leakage is obvious. Using advanced tracer gas and blower‑door assisted protocols, we locate and quantify discreet leakage paths around:
• Penetrations
• Joinery & access panels
• HVAC interfaces
• Utility service entries
Our detailed reports support commissioning sign‑off and include:
• Test results with ISO referencing
• Graphs, charts, and leakage profiles
• Recommendations and corrective strategies
Our specialists bring deep knowledge of cleanroom design, ISO test methods, and regulatory compliance frameworks.
We coordinate with design and construction teams to ensure airtightness is considered early - and resolved before costly rework.
We don’t just test; we help you get Aerotight - improving your facility’s performance, compliance posture, and operational sustainability.
High differential pressures and ultra‑low particulates demand airtightness precision beyond typical architectural spaces.
Contamination control, batch integrity, and compliance with ISO 14644 mandates airtight environments.
Cleanliness and particle control directly impact product safety and regulatory approval.
Our process is tailored, transparent, and designed for engineering alignment:

In semiconductor manufacturing, even sub-micron particles can cause catastrophic circuit failures on a silicon wafer. Air leakage through the cleanroom envelope introduces Airborne Molecular Contamination (AMC) and dust that bypasses HEPA/ULPA filters. Aerotight provides the precision integrity testing required to eliminate these "yield killers," ensuring your facility maintains the ultra-clean environment necessary for high-volume microchip production.
High-spec cleanrooms (ISO 1–5) rely on unidirectional (laminar) airflow. Any breach in the building envelope creates air turbulence, which disrupts this flow and allows contaminants to "settle" on sensitive wafers. Aerotight’s testing verifies that your physical boundaries are sealed, ensuring your laminar flow remains stable and your particle counts stay within ISO 14644-1 limits.
Semiconductor facilities use a positive pressure cascade (e.g., +30 Pa in Lithography, $+15\text{ Pa}$ in Etching). If the room envelope is leaky, the HVAC system cannot maintain these differentials, allowing "dirty" air from service chases or corridors to migrate into sterile bays. Aerotight uses high-resolution digital manometers to verify that your pressure hierarchy is robust and compliant with ISO 14644-4 design standards.
Yes. Microchip fabrication requires extreme environmental stability (often within Temperature variation: ±0.1°C
and Tolerance: ±1%>
humidity). Air leaks introduce unconditioned Australian ambient air, forcing HVAC systems into "hunt" mode and causing fluctuations that ruin photolithography precision. Aerotight helps you achieve a "hermetic" seal, stabilizing the internal climate and protecting your delicate chemical processes.
We use ultrasonic leak detection and theatrical-grade non-toxic smoke testing to find "invisible" bypass leaks. In semiconductor plants, leaks often occur at the junctions of the ceiling grid and HEPA filter housings. Our technicians can pinpoint these leaks without introducing any oily residues or contaminants that would compromise your cleanroom's ISO status.
Yes. Many semiconductor processes involve hazardous gases or volatile chemicals. An airtight envelope prevents the "cross-talk" of these chemicals between different fabrication zones. We verify the integrity of internal partitions to ensure that VOCs or outgassing from one process do not contaminate a sensitive "yellow room" or lithography bay.
Semiconductor cleanrooms are among the most energy-intensive buildings in Australia. By sealing the envelope, Aerotight reduces the "make-up air" volume required to maintain pressure. This significantly lowers the load on your fans and chillers, providing a direct ROI through reduced operational costs and helping facilities meet NCC Section J or Green Star energy targets.
The primary standards are ISO 14644-4 (Design, Construction, and Start-up) and ISO 14644-3 (Test Methods). While the NCC 2022 Section J provides general air permeability targets, semiconductor facilities often require much more stringent "gastight" levels. Aerotight provides the certified data needed to satisfy these rigorous global quality standards.
Testing should occur in two stages:
Yes. All Aerotight inspections culminate in a comprehensive, ATTMA-certified technical report. This documentation includes air permeability data, pressure-flow curves, and evidence of boundary integrity. These reports are essential for your Quality Assurance (QA) files and are designed to meet the documentation requirements of international semiconductor auditors.
Whether you’re early in design or finalising commissioning, Aerotight has you covered. Our experts speak your technical language and produce results your regulators, clients, and stakeholders can trust.
