Whether you're working on a new build or conversion project for either residential or commercial properties, air tightness testing is vital to ensure airtight facilities and superior ventilation. At Falcon Energy, we have years of experience at performing such tests on a range of properties across West Sussex, East Sussex, Surrey, Kent and nationwide.

What is Air Pressure Testing?

Air tightness, air pressure or air leakage testing is a skilled method of determining uncontrolled airflow, air leakage and unwanted drafts at a property which may result in heat loss. As such, a dwelling would not be deemed environmentally friendly and could prove expensive to run if it did not pass the test. Discover our guide to common sources of air leakage.

Since April 2006, new build and conversion properties have been required by law to comply with Part L of the Building Regulations. This states that the properties must undergo air tightness testing to ensure that they meet the standards of energy efficiency and do not have a high percentage of air permeability throughout the home.

By thoroughly tracing and monitoring air pressure and leakage, such heat loss can be eradicated along with the risk of CO2 emissions; a key principle of modern building regulations.

Depending on what type of property you have and the amount of homes in a development, the process to air tightness testing can differ slightly. Air pressure testing is only undertaken in a portion of homes within a development, and if they all pass the test then there is no need for further tests to be undertaken.

Effects of Air Leaks

Common household air leaks

  • Between Floor Joists behind Kneewalls
  • Attic Hatch
  • Wiring Holes
  • Plumbing Wires
  • Open Soffit (the box that hides recessed lights)
  • Recessed Light
  • Furnace Flue or Duct Chaseways (the hollow box or wall feature that hides ducts)
  • Basement Rim Joist (where the foundation meets the wood framing)
  • Gaps and cracks in walls

When is my property ready for air tightness testing?

Although air tightness testing cannot be undertaken until the property or properties are completed, instructing a qualified tester should be considered at the beginning of the construction process at the planning stage.

This is because if a knowledgeable energy company, such as Falcon Energy, are consulted from the beginning, then we can help to suggest best practices for energy efficiency at an earlier stage. This ensures that once the dwelling is complete, it has a far higher chance of passing and achieving compliance with building control.

As soon as the build is complete, then air tightness testing can begin. To find out more about the process involved with air tightness testing, read our blog.
