Precision Air Tightness Testing: Seal the Deal on Efficiency
An airtight building is the foundation of high-performance construction. Air Tightness Testing (also known as Air Permeability or Pressure Testing) is a critical requirement under Part L of the Building Regulations. It measures the extent to which air is “leaking” through the building envelope via gaps, cracks, and poorly sealed joints.
Why Air Tightness Matters
In modern construction, “building tight and ventilating right” is the gold standard. A successful air pressure test offers several key benefits:
- Energy Savings: Reducing uncontrolled draughts significantly lowers heating and cooling costs for the end-user.
- Structural Integrity: Proper sealing prevents moist air from entering the building fabric, reducing the risk of interstitial condensation and mold.
- Enhanced Comfort: Eliminating cold spots and draughts creates a more consistent and comfortable internal environment.
- Regulatory Compliance: Most new builds and conversions require a formal certificate to demonstrate compliance with the Target Emission Rate (TER).
Benefits of Air Tightness Testing
- Cost Savings: Improved energy efficiency leads to reduced utility bills.
- Environmental Impact: Lower air leakage contributes to reduced carbon emissions.
- Quality Assurance: Testing helps identify construction flaws and ensures compliance with building standards.
Air tightness testing is a crucial step in ensuring that buildings are energy-efficient, comfortable, and compliant with regulations.
Our Testing Process
provide a seamless, non-invasive testing experience designed to minimize disruption on-site:
- Pre-Test Advice: We provide a comprehensive checklist to help you prepare the building, ensuring windows, doors, and services are ready for a successful first-time pass.
- The Blower Door Test: Using calibrated fans, we depressurize and pressurize the building to measure the airflow rate at 50 Pascals (50Pa).
- Leak Detection: If a building fails to meet the target, we use smoke pens or thermal imaging to pinpoint exactly where the air is escaping.
Instant Reporting: Receive your results on-site, followed by a formal certificate for Building Control submission.
