We cater to projects of all scales, ranging from individual dwellings to expansive commercial structures. As one of the select few UKAS accredited companies, we specialise in both Air and Sound testing, ensuring full compliance with Building Regulations and Standards.

Our unique accreditation allows us to conduct Air, Sound, and Vent Testing all in one visit, offering clients cost efficiencies and streamlined on-site coordination. Unlike many firms, we handle all work directly without subcontracting.

Since its mandate in 2006 under Building Regulations Part L in England and Wales, achieving satisfactory levels of air tightness has become imperative. This requirement aligns with efforts to create environmentally friendly buildings by minimizing carbon emissions through the prevention of energy loss via air leakage. Part L defines ‘air leakage’ as the uncontrolled flow of air through a building’s gaps and cracks, commonly known as draughts.

Energy loss through the building fabric contributes to the building emission rate. New projects must adhere to specific air testing and emission rate standards. The typical target for a standard dwelling is 5.0m3/hr/m2, while commercial buildings often aim for lower rates, around 3.0m3/hr/m2.

Air infiltration usually accompanies exfiltration elsewhere in the building, potentially leading to issues like condensation, mould, or rot. Our consultancy services extend from the project’s design phase to pre-completion testing, ensuring compliance for building control signoff. For clients requiring weekend testing, we offer an ‘out of hours testing’ service to minimize disruption during weekdays.

Our combined air and sound testing packages provide substantial cost savings. With our engineers accredited in both disciplines, clients benefit from a streamlined ‘3 step’ pre-completion package, eliminating the need for multiple contractors. On-site coordination is enhanced, as both tests are conducted efficiently on the same day. Additionally, we offer out of hours testing to minimize disruption during standard working hours.

Conducting a Smoke Shaft Air Test

Many clients often inquire about the necessity of conducting air testing on their smoke shafts. Let’s delve deeper into the reasons behind this practice and how it ensures safety and compliance with relevant legislation and standards such as BS 9999 and BS 9991.

Smoke Shaft Air Test Services
If the shaft fails to achieve the airtightness target, a smoke leakage test is conducted. During the smoke test, theatrical smoke is pushed into the shaft, revealing any gaps or cracks in the smoke shaft envelope. on large smoke shafts over multiple floors, its best that multiple observers are used to check the floors whilst the air test engineer operates the blower fan equipment.

Smoke Control and Fire Safety
Smoke inhalation is a major cause of fatalities and injuries during fires, often overshadowing the direct impact of the fire itself. More than 60% of deaths in fire incidents occur due to smoke inhalation. Controlling smoke is crucial in safeguarding lives and property. Smoke control systems not only protect escape routes but also aid firefighters, thus reducing casualties.

1. Smoke Shaft Functionality: Smoke shafts play a pivotal role in evacuating smoke from buildings during a fire. To operate efficiently, smoke shafts must be airtight to facilitate the functioning of mechanical Automatic Opening Ventilation (AOV) systems, which extract smoke from escape routes. Air testing confirms the shaft’s airtightness before AOV commissioning, ensuring compliance and safety measures are met.
2. Building Regulations and Standards: Smoke shafts are subject to evolving regulations and standards in the UK. For residential buildings, BS 9991:2015 provides updated fire safety guidance, including recommendations for smoke control. Compliance with these regulations is essential to ensure the safety of occupants and adherence to legal requirements.
3. Air Testing Process for Smoke Shafts: Air tightness testing of smoke shafts involves a positive pressurization test using a high-powered blower door fan. This test is conducted with the shaft fully sealed but before AOV fans and louvres/shutters are installed. If the shaft fails to achieve the airtightness target, a smoke leakage test is performed. During the smoke test, theatrical smoke is introduced into the shaft to identify any gaps or cracks in the smoke shaft envelope.

In summary, air testing plays a crucial role in verifying that smoke shafts meet safety standards, thereby protecting lives and enhancing overall fire safety measures. At Air Pressure Testing Ltd, we specialise in conducting AOV smoke shaft testing, ensuring compliance and peace of mind for our clients.

Our experienced engineers and state-of-the-art equipment guarantee reliable results and professional service. From survey visits to smoke testing and thermal imaging, we offer comprehensive solutions to help you achieve smoke shaft signoff efficiently and effectively.

• UKAS Calibrated Equipment: Testing should be carried out using UKAS calibrated equipment to meet ISO 17025 air permeability standards.

For the most accurate and up-to-date information, it’s recommended to consult the official documents and any recent amendments provided by the UK government and relevant authorities for AOV Smoke shafts.

How Long will a typical smoke shaft air testing project take

The duration of a typical smoke shaft testing can vary based on factors such as the size of the building, the complexity of the smoke shaft system, and the testing methodology. However, I’ll provide a general estimate:

1. Small Buildings or Single Shafts: For smaller buildings with a single smoke shaft, the test may take 1 to 2 hours. This assumes straightforward access and minimal complications.
2. Larger Buildings or Multiple Shafts: In larger buildings, or those with multiple smoke shafts, testing can take a bit longer. Expect 2 to 4 hours or more, depending on the scope.
3. Preparation and Setup: Setting up the equipment, sealing openings, and ensuring safety precautions add to the overall time. Allow additional time for safety checks and coordination.
4. Testing Process: The actual air testing involves pressurising the shaft and measuring air leakage. The time spent on this step depends on the shaft’s size and complexity.
5. Reporting and Documentation: After testing, data analysis, reporting, and documentation take additional time. This includes recording results, identifying any issues, and recommending corrective actions.
6. Failed Air Test – If the shaft fails the test, a combined thermal imaging and smoke air leakage test can be undertaken, and a report collated. The time required to collate the report, varies depending on the size of the shaft and the amount of air leakage paths identified.
7. Remedial Work (if required): If the shaft fails the test, remedial work inside the shaft may be necessary. The time required for repairs or improvements varies depending on the amount of remedial works required and the ease of access to undertake the works.

Remember that accuracy and thoroughness are essential during smoke shaft testing. It’s crucial to follow established procedures and prioritize safety. Consult with experts to determine the specific duration for your building’s smoke shaft air test.

Introduction to Sound Insulation Testing

Sound insulation testing is a mandatory assessment according to Approved Document E, which evaluates the sound insulation efficacy of party walls and floors between dwellings. Typically conducted as properties near completion, the testing determines compliance with the minimum Building Regulation Part E standards for sound insulation.

The responsibility for arranging sound testing lies with the contractor, who must demonstrate to Building Control that the dividing partitions meet the requirements outlined in Approved Document E. This process is commonly known as Approved Document E (ADE) sound testing or pre-completion testing (PCT).

Sound Testing for Compliance with Approved Document E

Approved Document E, titled ‘Resistance to the passage of sound’, has been effective since July 1st, 2003, setting forth minimum sound insulation criteria for new and converted dwellings, encompassing various building types such as flats, houses, student accommodations, care homes, hotels, and schools.

This governmental document offers guidance to building contractors, architects, and developers involved in designing and converting residential buildings. It outlines the sound insulation standards for each building type and provides advice on acoustics, as well as details regarding construction procedures and materials that may impact sound test results.

Airborne and Impact Sound Testing

To meet the requirements of Part E, airborne sound testing for walls and floors typically necessitates achieving 45dB, while Impact Sound Testing for new builds requires reaching 62dB. However, in some cases, a higher target may be necessary to align with the Code for Sustainable Homes, often specified as +3, +5, or +8dB. For conversion properties, the targets are slightly lower at 43dB for airborne sound testing and 64dB for Impact Sound Testing.

Compliance with the Code for Sustainable Homes necessitates meticulous attention to acoustic design from the outset to mitigate the risk of sound testing failure.

Assistance in Achieving Compliance

Here at APT Sound Testing we provide specialist support in achieving these stringent design criteria and offer solutions if your building fails sound insulation testing, potentially saving time and costs.
