Achieve Green Star
Excellence with Aerotight

Future-proof your project. Lower your carbon footprint. Secure your Green Star rating with Australia’s leading airtightness solutions.

Aerotight provides precision airtightness testing and building envelope diagnostics to help you achieve Green Star certification, reduce compliance risk, and maximise building performance across Australia.

About Aerotight

Aerotight helps project teams deliver buildings that perform. As Australia’s leading airtightness consultancy, we provide design reviews, construction support, site inspections and compliance testing to ensure building envelopes achieve their airtightness and performance targets.

Our experience spans Green Star projects, healthcare facilities, Defence infrastructure, commercial developments, education and residential buildings throughout Australia and the Asia-Pacific region. By identifying risks early and working closely with project teams throughout design and construction, we help avoid costly rectification works and achieve successful compliance outcomes.

Workshop

Part of our unique process is to workshop the project team before the start of construction.

10 steps

This workshop is broken down into 10 steps that can be adopted by any company ranging from small residential to tier 1 commercial construction companies.

Equipment hire

We offer our clients equipment hire so that they can manage small scale testing of their project without the added cost

Commercial & Residential Airtightness Testing Across Australia

Aerotight sets the standard for high-performance buildings. Through expert consulting, design and airtightness testing, we work alongside project teams to mitigate construction and performance risk by identifying air leakage issues before they become costly site problems.

Guided by AS/NZS ISO 9972 and NCC requirements, we help teams reduce rectification risk, improve buildability and verify airtightness outcomes on completion – delivering compliant, efficient and durable buildings.

What is building airtightness?

Envelope permeability is the term given to building leakage and is measured in cubic meter (m3), per hour (h), per m2 (m2) of building envelope, or m3/h/m2. This measurement is taken at a differential pressure of 50Pa between inside and outside the building. It is tested with a blower door, which is a special type of fan designed to measure building leakage.
