Air Tightness Testing
Enhance Energy Efficiency with Air Tightness Testing
Air tightness testing is a critical process for measuring uncontrolled air leakage in a building. It ensures your building is properly sealed, minimizing heat loss and improving energy efficiency. Our services comply with Approved Document L of the Building Regulations.



Why is Air Tightness Testing Important?
Energy Efficiency
A well-sealed building requires less energy for heating and cooling, reducing energy bills.
Regulatory Compliance
Ensures your building meets legal requirements under Approved Document L.
Comfort and Indoor Air Quality
Reduces drafts and prevents moisture-related issues like condensation and mould.
Sustainability
Minimizes energy wastage, reducing your building's carbon footprint.
How is Air Tightness Testing Conducted?
Sealing of Controlled Openings
All intentional openings, such as trickle vents and extract fans, are temporarily sealed.
Installation of Blower Door Equipment
A powerful fan is fitted into an external doorway or window to create pressure differences.
Measurement of Air Leakage
The rate at which air escapes or enters the building is measured.
Identification of Leakage Points
Thermal imaging or smoke pencils are used to locate specific leakage areas.
Test Results and Certification
The building is certified based on compliance with required standards.
