Extractor Fan Testing Overview with APT Sound Testing

In adherence to the new regulations outlined in Part F of Building Regulations, it is now mandatory for standard intermittent extractor fans, commonly found in bathrooms and kitchens of new buildings, to undergo air flow rate measurement on-site. These results must be submitted to the building control body before completion and handover.

Our service facilitates extractor fan testing concurrently with air and sound testing, streamlining coordination efforts and offering significant cost efficiencies. Rest assured, our operations are conducted by a UKAS accredited company, ensuring quality and compliance.

Importance of Extractor Fan Testing

As modern buildings prioritize insulation and air tightness, it’s imperative that ventilation systems are appropriately installed, balanced, and commissioned to ensure optimal operation for occupants’ well-being. Approved Document F mandates that Mechanical Ventilation and Heat Recovery (MHVR) systems, along with intermittent extractor fans, have their flow rates verified, ensuring efficient operation. These test results are integral to building compliance and sign-off procedures.

In typical circumstances, we conduct Ventilation Flow Rate testing concurrently with on-site Air Pressure Testing, enabling streamlined compliance with both Part L and Part F regulations.

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.

The Pathway to Good Acoustic Design

There are many important acoustic design considerations when designing for apartment blocks, which requires both airborne wall and floor and impact floor testing to be taken into account.

Here are a few of the main acoustic considerations:

>>> Ensure all penetrations are fully sealed where they terminate through floors and they are adequately boxed with acoustic quilt and two layers of plasterboard.

>>> Avoid the use of lightweight blocks in the inner envelope construction as sound will travel both vertically and horizontally from dwelling to dwelling.

>>> The use of resilient suspended ceilings will help improve the performance of the floor partition.

>>> Ensure all support steels/timbers are carefully boxed out where they travel from flat to flat vertically and horizontally.

>>> Use a high quality resilient acoustic membrane on top of the floor to improve the impact performance of a floor.

By simply constructing a good separating wall or floor this may not in itself provide sufficient sound insulation to comply with Building Regulations Part E as the junctions of each separating wall and/or floor with other parts of the building are as equally important.

One of the main problems with partition failure is down to noise flanking, this can occur via construction components such as:

>>> The internal partitions
>>> The inner leaf of the external wall
>>> The external wall cavities
>>> The external façade or outer leaf
>>> The roof structure
>>> The foundations

The overall design and construction system should therefore be considered and not just the separating wall or floor partitions.  Flanking sound transmission may in some cases be the dominant pathway between adjoining dwellings, especially in existing buildings where you are planning to convert offices/large houses into flats, it can also be one of the main reasons for precompletion sound test failure.

In our experience if the acoustic design is taken into consideration from the offset of the project, then it usually results in compliance with Building Regulations Part E.  In Some cases, sound test failure can also be down to the poor workmanship rather than the acoustic design, that is why we offer a full acoustic package which includes for site survey visits; that way we have the acoustic design and onsite construction covered, reducing the chance of sound test failure.

So there its is, getting the acoustic design right from the word go, is key, and APT Sound Testing can help in all areas of sound insulation design and sound testing.

In a city where noise pollution is a constant concern, understanding the implications of sound testing on property values and occupant satisfaction is paramount. This article aims to delve into the intricacies of sound testing and its significance within the context of the London property market.

Understanding Sound Testing

Sound testing, also known as acoustic testing, is the process of assessing the sound insulation properties of buildings. It involves measuring the level of airborne and impact sound transmission between different spaces within a building, such as between adjoining apartments or rooms. The results of sound testing help determine whether a property meets the required standards for noise reduction, as outlined in building regulations and guidelines.

In the context of the London property market, where high-density living is common, sound testing plays a crucial role in ensuring the comfort and well-being of residents. Excessive noise from neighboring units or external sources can significantly impact the quality of life and property value. Therefore, property developers and homeowners alike must prioritize sound testing to mitigate noise disturbances and uphold the desirability of their properties.

Regulatory Framework and Standards

In the United Kingdom, sound testing is governed by building regulations set forth by the government. These regulations, particularly Part E of the Building Regulations, stipulate the minimum standards for sound insulation in residential buildings. Compliance with these standards is mandatory for all new constructions and conversions, ensuring that properties provide adequate protection against noise pollution.

In addition to regulatory requirements, various industry standards and guidelines, such as those established by the British Standards Institution (BSI), further define the criteria for sound testing procedures and performance metrics. Adhering to these standards not only ensures regulatory compliance but also enhances the marketability of properties by demonstrating their quality and suitability for habitation.

Impact on Property Values

The impact of sound testing on property values in the London market cannot be overstated. Properties that fail to meet sound insulation standards may experience diminished demand and lower resale values due to concerns about noise pollution. Conversely, those that excel in sound testing and offer superior acoustic performance are perceived as more desirable and command premium prices.

Research indicates that noise pollution can reduce property values by as much as 10% to 15%, depending on the severity of the issue and its perceived impact on residents’ quality of life. Therefore, investing in sound testing and implementing effective noise mitigation measures can yield significant returns for property owners in terms of increased market value and attractiveness to prospective buyers or tenants.

Occupant Satisfaction and Retention

Beyond its financial implications, sound testing also directly influences occupant satisfaction and retention rates in residential properties. Residents value peace and quiet as essential aspects of their living environment, and noise disturbances can lead to dissatisfaction and discomfort. Consequently, properties that undergo thorough sound testing and address any acoustic deficiencies are more likely to retain tenants and foster positive living experiences.

Property developers and landlords who prioritize sound insulation not only attract tenants seeking tranquility but also cultivate a reputation for providing high-quality accommodations. This, in turn, contributes to tenant loyalty and positive word-of-mouth referrals, enhancing the property’s long-term sustainability and profitability in the competitive London rental market.

Challenges and Considerations

While sound testing offers numerous benefits for property owners and occupants alike, it is not without its challenges and considerations. Achieving compliance with sound insulation standards can be complex and may require careful planning, design, and construction methods. Factors such as building materials, layout configurations, and environmental conditions can all influence the effectiveness of sound testing measures.

Moreover, retrofitting existing properties to improve sound insulation can be costly and disruptive, particularly in densely populated urban areas like London. Property owners must weigh the potential costs and benefits of sound testing initiatives against the perceived value they add to the property and the overall satisfaction of occupants.

Future Trends and Innovations

As technology continues to advance, so too do innovations in sound testing and noise mitigation solutions. From advanced acoustic modeling software to specialized building materials engineered for sound insulation, developers have access to a growing array of tools and techniques to enhance the acoustic performance of properties.

Furthermore, the growing awareness of the impact of noise pollution on health and well-being is prompting policymakers and industry stakeholders to explore new strategies for addressing acoustic concerns in urban environments. Initiatives such as the implementation of quiet zones, sound-absorbing infrastructure, and urban planning policies that prioritize noise reduction are gaining traction, shaping the future landscape of the London property market.

Sound testing is an essential aspect of property evaluation in the dynamic and competitive London real estate market. From ensuring regulatory compliance to enhancing property values and occupant satisfaction, sound testing plays a multifaceted role in shaping the desirability and sustainability of residential properties.

Property developers, homeowners, and investors must recognise the importance of sound testing and prioritise acoustic performance in their development and renovation projects. By investing in sound insulation measures and embracing innovative solutions, stakeholders can create living environments that offer tranquility, comfort, and long-term value in the bustling metropolis of London.

Cost Effective Soundproofing for Walls

There are many soundproofing solutions for walls; however, not all are cost effective. Have a look at the Gyplyner system below, it’s quite a robust and cost-effective solution as it reduces the build-up of an independent wall solution, whilst maintaining good soundproofing properties, this system would lose you about 52mm with skimmed 15mm sound board, or 62mm with two layers of 12.5mm soundboard. It’s a good off the shelf solution as the GL1 profile is held in stock by most large building merchants and the brackets a just screwed to the wall and bent round, then screwed to the GL1 profile, which makes it quite quick and easy to install – as per the detail below.

Sometimes a single skin of lightweight blocks (such as thermalite) may have been used in the party wall construction which is a poor soundproof wall construction due to its lack of mass. This type of masonry may be only 500kg/m3 (50kg/m2), masonry should be around 1850kg/m3 (185kg/m2) which can easily lead to sound test failure if used in the inner envelope construction and or party walls.

It’s worth remembering for sound to conduct through a wall, it has to actually move or vibrate the party wall ever so slightly. A heavy mass wall is always much harder to move than a lighter wall. It is very important to note that a heavy wall will still vibrate, just not as easily as the lighter one.

If you understand the above elements that make up party wall and floor design and construction, you’ll have a more educated eye for the acoustic design on your dwelling,  for instance, the  4 main elements of soundproofing construction are:

1. Adding mass in your party walls
2. Decoupling of materials within party walls
3. Noise absorption within party walls
4. Noise damping in party walls

In a nutshell soundproofing is the art of trying to prevent vibrations crossing party walls and floor partitions.

Getting the acoustic design right from the word go, is key, and APT Sound Testing can help in all areas of sound insulation design and sound testing. Please get in touch on info@aptsoundtesting.co.uk  to request a quote or call us on 07775 623464 or 01525 303905 to discuss your development.

Unveiling the Importance of Air Tightness Testing in Building Construction

In the realm of modern construction, ensuring energy efficiency and comfort within buildings has become paramount. One often overlooked aspect contributing significantly to energy efficiency is air tightness. The leakage of air through the building envelope can lead to increased energy consumption, decreased indoor air quality, and compromised thermal comfort.

To address these concerns, air tightness testing has emerged as a crucial diagnostic tool for assessing the performance of buildings. In this comprehensive guide, we delve into the significance of air tightness testing, its methodologies, and its implications for building design and construction.

Understanding Air Tightness Testing:

Air tightness testing, also known as air leakage testing or blower door testing, involves the quantification of the uncontrolled airflow through the building envelope. It aims to identify areas of air leakage, typically at joints, gaps, and penetrations in the building structure. The testing process employs specialized equipment such as a blower door, which consists of a powerful fan mounted within a frame that fits into an exterior door opening. By depressurizing or pressurizing the building interior relative to the exterior, the blower door measures the airflow rate, allowing for the calculation of air changes per hour (ACH) or air permeability metrics such as the air leakage rate (ALR) or air leakage index (ALI).

Significance of Air Tightness Testing:

1. Energy Efficiency: Enhanced air tightness reduces the infiltration of outside air, thereby minimizing the loss of conditioned air and reducing the energy required for heating, cooling, and ventilation. By identifying and sealing air leaks, buildings can achieve substantial energy savings and lower operational costs over their lifespan.
2. Thermal Comfort: Air tightness plays a pivotal role in maintaining consistent indoor temperatures and preventing drafts, cold spots, and heat loss during the winter months. By mitigating thermal bridging and convective heat transfer, well-sealed buildings offer improved comfort for occupants, promoting productivity and well-being.
3. Indoor Air Quality (IAQ): Uncontrolled air leakage can introduce pollutants, allergens, and moisture into indoor spaces, compromising IAQ and exacerbating respiratory issues. Air tightness testing helps identify sources of infiltration, allowing for targeted interventions to mitigate indoor air pollutants and enhance occupant health and comfort.
4. Moisture Management: Air tightness is closely linked to moisture control within buildings. Excessive air leakage can lead to condensation, mold growth, and moisture-related damage to building materials. By minimizing air infiltration, air tightness testing aids in preventing moisture ingress, safeguarding structural integrity, and prolonging the lifespan of building components.

Methodologies for Air Tightness Testing:

1. Blower Door Test: The blower door test is the most widely used method for assessing air tightness in buildings. It involves the installation of a blower door system in an exterior door opening, followed by the pressurization or depressurization of the building interior to measure airflow rates. The results are used to calculate air leakage metrics and identify areas requiring air sealing interventions.
2. Smoke Pencil Test: The smoke pencil test is a qualitative method for detecting air leaks visually. It involves the use of a handheld smoke generator to emit a thin stream of smoke near potential leakage points, such as window frames, doors, and electrical outlets. The movement of smoke indicates the presence of air leaks, aiding in the identification and sealing of problematic areas.
3. Infrared Thermography: Infrared thermography utilizes thermal imaging cameras to detect temperature differentials associated with air leakage. By visualizing thermal patterns on building surfaces, infrared thermography helps pinpoint areas of heat loss and air infiltration, guiding targeted air sealing efforts for optimal energy performance.

Implications for Building Design and Construction:

1. Design Optimization: Air tightness testing informs the design process by identifying potential air leakage pathways and highlighting opportunities for improving the building envelope’s performance. Architects and engineers can integrate air sealing strategies early in the design phase to minimize thermal bridging, enhance insulation continuity, and optimize the overall energy efficiency of the building.
2. Construction Quality Assurance: During construction, air tightness testing serves as a quality assurance measure to verify that the building envelope meets specified performance standards. By conducting pre-completion tests, contractors can identify and rectify air leakage issues before occupancy, ensuring that the building performs as intended and meets regulatory requirements.
3. Building Retrofit and Renovation: Air tightness testing is equally relevant for existing buildings undergoing retrofit or renovation projects. By assessing the air tightness of the building envelope, retrofit professionals can prioritize air sealing measures to improve energy efficiency, comfort, and IAQ while minimizing disruption to occupants and preserving the building’s architectural integrity.
