Final Airtightness Testing
Final Airtightness Testing for Compliance & Certification
Greenfield Controls offers comprehensive final airtightness testing to confirm your building meets all regulatory requirements before handover. Our testing process ensures compliance with Building Regulations Part L, helping you secure the required certification for project completion.
Why Final Airtightness Testing is Critical?
A building’s airtightness is a key factor in energy efficiency, indoor comfort, and regulatory approval. Without proper testing, undetected leaks can lead to compliance failures, additional costs, and delayed project sign-offs. Ensuring a fully sealed structure is essential before final inspections and occupancy.
Failing an Airtightness Test Can Delay Handover
Builders and developers often encounter last-minute airtightness issues that:
Fail compliance tests, requiring unexpected repairs.
Increase energy consumption, reducing the building’s efficiency rating.
Cause discomfort for occupants, with drafts and temperature fluctuations.
Delay handover & certification, affecting project timelines.
Final airtightness testing ensures that all sealing and insulation measures have been properly executed, avoiding costly setbacks.
