Understanding Air Permeability Testing
Air permeability testing is crucial to ensuring that buildings achieve the desired energy efficiency and ventilation standards. At Ratio Seven, we understand that a thorough Air Permeability Testing Preparation is key to success. This article provides detailed guidance on on-site preparation for air permeability testing, ensuring you are well-prepared and can achieve accurate results.
The Importance of Air Permeability Testing
Conducting an air permeability test is essential for:
- Verifying building envelope performance.
- Ensuring compliance with building regulations.
- Identifying and rectifying air leakage points.
A successful testing process can provide a detailed insight into the building’s airtightness level, ultimately helping to reduce energy consumption and enhance comfort.
Preparing Your Site for Air Permeability Testing
Effective site preparation for air permeability testing is critical. Follow these guidelines to ensure a seamless testing process:
1. Complete All Structural Work
Ensure all structural work on the building is finalized. This includes:
- Installing windows, doors, and fans.
- Completing all masonry and plastering work.
- Ensuring that all trap doors, loft hatches, and delivery holes are sealed.
2. Seal Unintended Openings
Focus on sealing any unintended openings such as:
- Gaps around pipes, cables, and wiring.
- Spaces around door and window frames.
- Cracks and joints in the building materials.
3. Install Temporary Seals Where Necessary
Temporary seals are crucial for achieving accurate test results. Apply seals to:
- Chimney stacks.
- Ventilation ducts not yet fitted with mechanical ventilation.
- Service holes that are not yet in use.
4. Ensure Ventilation Systems are Properly Installed
Verify that every component of the ventilation system is correctly installed and operational. This includes:
- Extraction fans and air bricks.
- Mechanical ventilation with heat recovery (MVHR) systems.
- Passive stack ventilation systems.
5. Prepare Internal Spaces
The internal state of the building can influence test results. Make sure that:
- Interior doors are wedged open.
- Drainage traps are filled with water.
- Floor coverings are laid where necessary.
Common Mistakes to Avoid During Air Permeability Testing Preparation
Avoid the following common mistakes to ensure accurate testing:
- Leaving structural openings unattended.
- Neglecting to seal small, unintended gaps and cracks.
- Overlooking the importance of internal preparations.

FAQs
What is the purpose of air permeability testing?
Air permeability testing aims to measure the airtightness of a building. It helps in identifying air leakage points, ensuring compliance with building regulations, and improving energy efficiency.
When should an air permeability test be conducted?
The ideal time to conduct an air permeability test is after all structural work is complete but before final finishes are applied. This allows for the identification and rectification of any air leakage points without causing significant disruption.
How can I ensure accurate air permeability test results?
Accurate results can be ensured by meticulously following the air permeability testing preparation guidelines. Ensure all unintended gaps are sealed, the ventilation system is properly installed, and the internal space is properly prepared.
