Envelope Pressure Testing

Residential Envelope Pressure Testing is a crucial component of building design and construction in Australia.

During this, we typically evaluate the current and potential air leakage of a home’s exterior envelope, including walls, windows, doors, and the roof. Our testing methods will measure the air infiltration and exfiltration of the building, which can lead to increased energy usage, poor indoor air quality, and a less comfortable living environment. The testing process involves using specialised equipment to pressurise and depressurise the building while measuring the air pressure differentials.

Residential Envelope Pressure Testing is typically required for new residential properties in Australia and for major renovation projects or additions. The National Construction Code (NCC) mandates that all new buildings comply with strict energy efficiency standards, including air-tightness requirements. The NCC is responsible for outlining the acceptable levels of air leakage for different climate zones in Australia, and the testing process is used to verify compliance with these standards.

An Envelope Pressure Test, often known as a blower door test, is a simple way to check how well-sealed your home is. Whether your home is new or older, this test can find spots where air leaks out or drafts get in. Fixing these can improve energy efficiency and comfort in your home.

We have developed 3 packages tailored to meet varying needs and preferences.

Standard Inspection
Advanced Diagnosis
Premium Validation
The Standard Inspection pack includes a certified envelope pressure test for building leak detection, validated with an ATTMA certificate.In addition to the Standard Inspection features, the Advanced Diagnosis pack enhances your insight with detailed leak analysis, supplementary reports, and photographic evidence.The Premium Validation pack builds upon the Advanced Diagnosis with the inclusion of a re-test, ensuring the most thorough and reliable building integrity validation.

What are the benefits of a Blower Door Test?
  1. Find air leaks: The test pinpoints where outside air is getting in and conditioned air is escaping, making your heating and cooling system more efficient.
  2. Reduce energy use: Fixing these leaks means your home’s heating and cooling systems work less hard, saving energy.
  3. Help your A/C last longer: Using less energy means less stress on your A/C system, which can make it last longer.
  4. Make your home more comfortable: Sealing leaks and improving insulation helps keep your home’s temperature consistent.
  5. Avoid moisture problems: This test can help you avoid issues like mould, which can be costly if they get out of control.
  6. Improve Indoor Air Quality: Reduce the entry of outside pollutants and allergens, enhancing the air quality inside your home.
  7. Soundproofing: A better-sealed home helps to reduce external noise.
  8. Sustainability: Enhance your home’s energy efficiency, reduce energy bills, and decrease carbon footprint.
  9. Preserve Home Structure: By controlling moisture levels, maintain the long-term physical integrity of your home.
  10. Potential Increase in Property Value: Energy efficiency can be a selling point, potentially boosting your property’s market value.
