What Is Air Tightness Testing?

Air tightness testing is the process of measuring the extent to which a building prevents air leakage through its envelope. This testing often involves using blower door equipment to pressurise or depressurise a building, identifying areas where air may be escaping or infiltrating.

At Apex Energy Assessments, we use pressurisation and depressurisation techniques to detect and quantify air leaks.

This is crucial for maintaining energy efficiency, controlling ventilation, and ensuring indoor air quality. Proper testing helps minimise energy loss, supports climate control systems, and can reduce energy bills.

We adhere to the ATTMA (Air Tightness Testing and Measurement Association) standards, ensuring that our methods align with industry best practices.

Our service in Eltham is designed to help buildings comply with Part L of the Building Regulations, which mandates specific air leakage rates for different property types. Partner with us to ensure your building meets these regulatory requirements.

When Is Air Tightness Testing Needed in Eltham?

Air tightness testing in Eltham is typically needed when a building is being constructed or renovated. It ensures compliance with legal standards and helps improve energy efficiency.

Newly constructed buildings usually require testing before completion to meet Building Regulations Part L. In particular, non-domestic properties such as offices and retail units often need testing due to their complex designs and larger volumes of air exchange. Additionally, refurbishments and major renovations often trigger the need for testing to ensure new works do not compromise air tightness.

Testing can also be beneficial during retrofitting projects, especially when installing new insulation or windows, as it ensures these elements perform optimally. The tests measure air permeability using equipment like blower doors, identifying potential leakage areas.

Understanding when testing is needed helps prevent issues related to energy inefficiency and drafts. Contact us to find out when your project might require testing.

How Does Air Tightness Testing Work?

To conduct air tightness testing, we follow these steps:

Preparation: We seal and pressurise the building using a calibrated blower door. This equipment is crucial for creating controlled conditions without external air interference. Before initiating the test, we ensure that all external doors, windows, and vents are securely closed.
Measurement: We measure the air leakage rate by calculating the airflow needed to maintain a set pressure difference, typically 50 Pascals. This data is essential for determining the building's energy efficiency and compliance with standards such as Part L of the Building Regulations.
Detection: We identify leakage points using smoke pens or infrared cameras. These tools help pinpoint areas of air leakage, such as gaps around window frames or poorly sealed joints, allowing us to address potential energy losses effectively.
Analysis: We provide a detailed report on the building's air tightness performance. Our report includes an evaluation against current compliance standards and recommendations for improvements, aiding our clients in enhancing their energy conservation efforts.

How Long Does Air Tightness Testing Take?

Air tightness testing typically takes between two to four hours per building, depending on its size and complexity. For a standard test, we use a blower door system to measure the air infiltration rate, sealing all intentional ventilation openings.

Larger or more complex properties, such as commercial buildings or multi-storey residences, may take longer and sometimes require additional equipment like duct testing apparatus for HVAC systems. Most single dwelling tests in Eltham are completed within half a day.

We follow protocols set by standards such as ATTMA TSL1 to ensure accuracy. The results are usually available immediately after the test, allowing for prompt action if any issues are identified.

This timely availability of results helps construction companies and homeowners address and rectify any air leakage problems efficiently. If you're interested in booking a test, contact us to schedule your assessment.
