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 and East Sussex, Surrey, Kent and nationwide.
What is Air Pressure Testing?
Air tightness or pressure 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 property would not be deemed environmentally friendly and could prove expensive to run.
By thoroughly tracing and monitoring air pressure and leakage, such heat loss can be eradicated along with the risk of CO2 omissions; a key principal of modern building regulations.
There are many benefits to air tightness testing with Falcon Energy including:
The reduction of potentially harmful CO2 emissions
Lower energy and heating bills
Adherence to building regulations and guidelines
Why work with Falcon Energy?
Our expert team of technicians are not only fully qualified and affiliated to IATS (Independent Airtightness Testing Scheme), but are highly skilled and extensively experienced at performing such rigorous, thorough testing. With our team being recognised by the IATS, you're guaranteed to be in safe hands with Falcon Energy and can expect the very best, professional service.
We'll offer invaluable, insightful advice at the very start of a project, big or small, domestic or commercial, and our team will work closely with you and any architects or builders to ensure a pass is achieved. Our nationwide services are second to none and can be completed at a time to suit you. What's more, our air permeability testing is reliable and cost effective; what's not to love?
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
- Furenace Flue or Duct Chaseways (the hollow box or wall feature that hides ducts)
- Basement Rim Joist (where the foundation meets the wood framing)
Frequently Asked Questions
Why are homes built to be airtight?
To reduce air leakage of a building and to lower the results of the air tightness test. This reduces the amount of energy required to maintain comfort levels and in turn, reduces carbon dioxide emissions from heating.
Having an airtight home is both environmentally and financially efficient and saves homeowners money in the long term.
Why do we test air tightness in domestic properties?
Proving the air tightness standard of a building is now required under Part L of the Building Regulations. Domestic energy accounts for more than 25% of the UK's CO2 emissions, which the UK Government aims to reduce overall.
As a result, it’s an important certification for developers in new build projects.
What’s our process for measuring air pressure?
Air Leakage in buildings is measured by installing a large fan temporarily on-site to measure the pressure differential across the envelope of the property.
Throughout the test, the fan is used to gradually increase and decrease the pressure, which allows for a range of pressure and environmental readings to take place. The differential pressure is recorded between 25-70Pa (Pa is the unit of measurement for air pressure - ‘pascal’).
50Pa is the required air flow differential, so the total airflow needed to achieve this is calculated and divided by the total building envelope. This results in a leakage rate (m3/h/m2@50Pa).
What are air leakage paths?
They’re the opposite of controlled air flow that you might experience with purpose built ventilators that result in desired air flow.
Air leakage paths are uncontrolled air flows and are undesired. These instances can occur through cracks in a building’s fabric, or even gaps.
Once these paths are discovered, they should be fixed to reduce or stop air leakage.
