Thermal Imaging for Locating Building Defects in London

Thermal imaging surveys offer an innovative and highly efficient way to detect building defects without causing any damage to the structure. These surveys use infrared technology to provide a non-invasive means of inspecting all types of commercial buildings. The benefits of thermal imaging in building inspections are significant, particularly in restoration and remediation projects, where it aids in identifying issues swiftly and accurately. Moreover, this technique eliminates the need for destructive investigations, such as tearing down walls or ceilings, which can be costly and time-consuming.

Thermal Imaging for Locating Building Defects
One of the most important advantages of thermal imaging is its ability to reduce health and safety risks. Traditional inspections often require access to high, hard-to-reach places, necessitating the use of scaffolding or access platforms. With thermal imaging, inspections can be conducted from the ground or other accessible points, eliminating the need for inspectors to work at heights. This reduces the risks of accidents and ensures that the inspection process is safer and more efficient.

The effectiveness of thermal imaging lies in the combination of advanced infrared cameras and the expertise of highly trained Level 3 engineers. These professionals are equipped with the knowledge and experience to interpret the thermal images correctly and document any issues they find. Additionally, after repairs or remediation work is completed, thermal imaging can be used again to verify that the work was carried out properly, ensuring that the building is in good condition.

Common Building Defects Identified Using Thermal Imaging

Thermal imaging can detect a wide range of building defects that might not be visible during a standard inspection. Here are some of the most common issues that can be uncovered:

Water Leaks in Roofs, Walls, and Floors

One of the most frequent problems discovered during thermal imaging surveys is moisture intrusion, particularly in roofing materials. When water penetrates a roof, it can significantly reduce the insulation properties of the roofing material. Infrared cameras can detect these moisture spots by identifying temperature differences, allowing engineers to pinpoint the exact areas where repairs are needed. In many cases, this can extend the life of a roof by addressing small issues before they become more serious, thus avoiding the costs of a full replacement.

Moisture infiltration is not limited to roofs; it can also affect walls and floors. Similar to roof inspections, thermal imaging can detect damp areas in these parts of the building. Dampness causes changes in temperature that are visible on infrared cameras because wet areas retain and release heat at a different rate than dry areas. The presence of moisture in walls or floors can lead to problems such as mold, mildew, and air quality issues. Over time, exposure to poor air quality can lead to health concerns for the occupants of the building, making early detection and remediation of moisture issues critical.

Air Leakage Around Windows, Doors, and Building Openings

Another common issue that thermal imaging helps to uncover is air leakage through windows, doors, and other openings in the building’s envelope. Air leaks can have a significant impact on a building’s energy efficiency by allowing conditioned air (either heated or cooled) to escape, which results in higher energy consumption and costs.

In combination with blower door testing, thermal imaging becomes an especially powerful tool for identifying air leaks. Blower door tests create pressure differences inside the building, making air leaks more apparent. When thermal imaging is used during this test, it becomes easy to visualize where the conditioned air is escaping. Addressing these leaks can dramatically improve a building’s energy efficiency.

Poor or Missing Insulation

Thermal imaging is also effective at identifying areas with missing or poorly installed insulation. In many of the surveys conducted, significant energy loss has been traced to areas where insulation is either absent or damaged. This could be the result of improper installation, degradation over time, or other issues.

A thermal imaging survey can reveal these problem areas by highlighting the differences in thermal patterns. Areas with missing or damaged insulation will exhibit a different heat signature compared to properly insulated sections of the building. Correcting these deficiencies can lead to a reduction in energy loss, which translates into lower heating and cooling costs.

Thermal Bridging in Structural Elements

Thermal bridging occurs when heat flows through materials with higher thermal conductivity, such as steel beams or concrete, bypassing the insulation designed to prevent heat transfer. This is a common issue in many existing buildings and can lead to higher energy consumption due to uncontrolled heat transfer.

Thermal bridges can be detected using infrared cameras, which reveal areas where heat is being conducted through the building envelope. Once identified, steps can be taken to minimize these thermal bridges, either through better insulation or changes to the building’s design. Reducing thermal bridging can improve the overall energy efficiency of a building and contribute to a more comfortable indoor environment.

Thermal Imaging for Renovation & Retrofit Projects

Thermal imaging is particularly valuable when preparing for renovation or retrofit projects. Before starting any work, a thermal survey can help uncover hidden issues in the existing structure, such as moisture, air leaks, or insulation problems. Identifying these problems early in the process allows building owners and contractors to address them before beginning the renovation, which can prevent costly delays and complications down the line.

Conducting a thermal imaging survey both before and after renovation work is also a useful way to verify that the work was done correctly. This ensures that any retrofitting done to improve energy efficiency is as effective as possible, and it provides peace of mind that the building is safe and healthy for its occupants.

BREEAM Thermal Imaging Surveys

For buildings seeking BREEAM (Building Research Establishment Environmental Assessment Method) certification, thermal imaging can play a critical role. BREEAM is a globally recognized sustainability assessment method for infrastructure and buildings, and thermal imaging surveys are often a key requirement for achieving this certification.

What is Sound Insulation Testing for Flats?

What Sound insulation testing is a process that checks if a building meets the necessary acoustic standards. It is required for new and converted dwellings according to building regulations. The sound testing should be undertaken by suitably qualified testers who hold approved third-party accreditation such as a UKAS accredited sound testing company.

The sound insulation testing involves two main aspects:

Airborne Sound Insulation: This relates to sound that travels via the air and through separating structures between rooms. For example, airborne sound across a lightweight floor would pass through the plasterboard ceiling, into the floor void, through the floorboards, and into the room.

Impact Sound Insulation: This measures the noise level in a room when an impact source is applied directly to the floor above.

The specific acoustic performance requirements for new builds and conversions are set within Approved Document E ‘resistance to the passage of sound. The criteria for refurbishments are slightly more lenient than for new builds, recognizing that it can be more difficult to soundproof an existing structure.

For compliance with the Building Regulations, the acoustic testing must be conducted by a qualified acoustic engineer who is accredited to conduct sound testing by an organisation such as UKAS accredited testing laboratory

Floor Plenum Testing Services by APT Sound Testing

APT Sound Testing provides thorough floor plenum testing in alignment with the Floor Plenum Airtightness – Guidance and Testing Methodology (BG 65/2016). Our testing services are vital for ensuring that conditioned air is efficiently distributed from the floor plenum to the occupied spaces, without leaking into unintended areas like cavities, risers, stairwells, or other adjacent zones. Proper sealing of the floor plenum is crucial to allow diffusers and grilles to deliver air at the correct flow rates, thereby enhancing both energy efficiency and comfort within the building.

What is a Floor Plenum?

A floor plenum is a space between the structural floor of a building and the raised access floor above it. This void is typically utilised for the distribution of conditioned air throughout the building, supporting HVAC systems by providing pathways for either supply or return airflows. The air within the plenum is usually maintained at a pressure higher than the atmospheric pressure to facilitate its movement into the occupied areas above.

However, this setup presents a potential for air leakage, which can lead to significant energy inefficiencies and discomfort for occupants. Ensuring that the conditioned air flows directly into the occupied zones, rather than leaking into cavities, risers, or other unintended areas, is essential for maintaining both the efficiency of the building’s HVAC system and the comfort of its users.

Importance of Floor Plenum Sealing

Properly sealing the floor plenum ensures that the air supplied to this void is discharged through floor-mounted diffusers or grilles, rather than escaping through joints in the raised access floor or between the floor and walls. This is critical because unintentional air leakage can disrupt the designed air distribution, leading to uneven heating or cooling, increased energy consumption, and potential discomfort for building occupants.

To prevent these issues, the floor plenum must be constructed and sealed meticulously. The materials used, the quality of the construction, and the precision in sealing all joints and penetrations are crucial factors in achieving the desired airtightness.

How We Conduct Floor Plenum Testing

At APT Sound Testing, we use specialised equipment to conduct floor plenum airtightness tests. The testing process involves the use of a fan, which is set up within the test zone to measure the pressure differences and detect any air leakage. Prior to testing, all air ducts must be turned off and sealed to ensure that the readings are accurate and reflective of the floor plenum’s airtightness.

The test consists of taking a series of pressure readings across different points within the plenum. These readings help us determine whether the plenum meets the required airtightness standards. If the plenum fails the test, we can conduct a smoke survey to identify the specific paths where air is leaking. This allows us to provide a detailed report highlighting the areas that need remedial sealing work.

Why Floor Plenum Airtightness Matters

The airtightness of a floor plenum is a critical factor in the overall performance of a building’s HVAC system. When air leaks occur within the plenum, it can result in reduced efficiency of the system, leading to higher energy consumption and increased operational costs. Additionally, air leakage can cause uneven distribution of conditioned air, leading to hot or cold spots within the building, which can significantly impact occupant comfort.

Moreover, uncontrolled air leakage can interfere with the building’s ability to maintain proper indoor air quality. By allowing conditioned air to escape or allowing unconditioned air to enter the plenum, the building may struggle to maintain the desired temperature and humidity levels, potentially leading to an uncomfortable or unhealthy indoor environment.

Key Considerations for Floor Plenum Construction

When constructing a floor plenum, several important considerations must be taken into account to ensure its airtightness and overall effectiveness:

1. Alignment of Carpet Tiles and Floor Panels: In many office buildings, carpet tiles are installed over the raised access floor. If the joints between these tiles are not aligned with the joints of the underlying floor panels, air leakage can be minimized, especially if the carpet tiles are glued in place. However, relying solely on carpet tiles for airtightness is not advisable, as they may de-bond over time.
2. Sealing Electrical and Data Boxes: Raised access floors often include electrical and data boxes. The air leakage potential of these boxes should be evaluated to ensure they do not significantly contribute to overall floor leakage, which could reduce the efficiency of air delivery to grilles and diffusers. Any penetrations for cabling or other utilities should be sealed properly to prevent air leakage.
3. Perimeter Sealing: The perimeter of the floor plenum, where the access floor meets the wall, is often a critical area for air leakage. To reduce this, it may be beneficial to install a metal angle along the perimeter, combined with closed-cell board or neoprene strips, to enhance the seal and prevent excessive air leakage.
4. Wall Construction and Sealing: The walls of the floor plenum are particularly vulnerable to air leakage. Plasterboard can be used as an airtight barrier, but it is essential to ensure that all joints are sealed, especially where the boards meet other boards, walls, floors, and the underside of the raised access floor. Similar precautions should be taken with coated mineral fire boards used in conjunction with fire mastic. The boards should have a specified air leakage rate of 0.15 l/(s.m²)@50Pa and a life expectancy of at least 25 years.
5. Concrete Floors and Joint Sealing: While poured in-situ concrete floors generally do not have significant air leakage issues, other types such as hollow-core and solid composite precast planks require careful sealing along the plank joints. Beam and block floors should be covered by a screed to prevent excess air leakage.

Common Air Leakage Paths in Floor Plenums

To create an airtight floor plenum, it is essential to identify and properly seal all potential air leakage paths. During the early design phase and throughout construction, a thorough evaluation of the following common leakage points should be conducted:

1. Utility Penetrations:
   • Cable Bundles and Trays: Any penetrations through the access floor, walls, and subfloor for cables must be sealed to prevent air leakage.
   • Pipes: Similar to cables, all pipe penetrations should be properly sealed.
   • Fire/Plenum Barriers: These barriers must be airtight to prevent air from bypassing the intended flow paths.
2. Cable Trunking: The interior of cable trunking within the plenum should be sealed to prevent air from escaping into unwanted areas.
3. Masonry Work: Poorly jointed or incomplete masonry can be a significant source of air leakage. Ensuring that all masonry work is properly executed is crucial for maintaining airtightness.
4. Risers and Ducting: Proper sealing of risers and ducting within the plenum is necessary to prevent air leakage and ensure efficient air distribution.
5. Plasterboard Sealing: All edges and ends of plasterboard below the raised floor level should be sealed to prevent air from escaping.
6. Compartment Barriers: Gaps between compartment barriers, the top of the raised access floor, and the subfloor should be sealed to prevent air leakage.
7. Curtain Walling/Glazing: Any gaps between curtain walling or glazing and the plenum should be sealed to prevent air leakage.

This step provides us with a detailed and accurate overview of the acoustic performance of the existing partitions. Understanding the current sound insulation levels is essential for developing a targeted acoustic design. By measuring the actual performance of your building’s partitions, we can identify any weaknesses and suggest specific improvements to enhance sound insulation. This data-driven approach ensures that the acoustic design we propose is tailored to the unique characteristics of your building, maximizing the effectiveness of the soundproofing measures we recommend.

Step 3: Acoustic Design Review

Once we have gathered all necessary data from the site survey and sound testing, we conduct a full acoustic design review. This comprehensive analysis focuses on the party walls and floors of the proposed development, ensuring that every aspect of the acoustic design meets the requirements of Building Regulations Part E. Our design review includes a detailed examination of the mass, isolation, and absorption properties of the construction materials and methods being used. We assess whether the proposed design will effectively mitigate noise transmission between adjoining spaces, and we suggest modifications where necessary to optimise acoustic performance. Our goal is to deliver a design that not only complies with regulations but also enhances the overall acoustic environment of the building, contributing to a more comfortable and functional space for occupants.

Step 4: Pre-Completion Sound Testing

The final step in our process is pre-completion sound testing, which is essential for satisfying the requirements of Approved Document E. This testing is typically requested by local authorities to verify that the building meets the required sound insulation standards before completion. Our team conducts thorough sound insulation tests on the finished partitions, ensuring that the construction meets or exceeds the standards set out in Building Regulations Part E. If any issues are identified during this testing phase, we provide immediate recommendations for corrective actions, helping you to achieve compliance without delay.

Commercial BS4142 Noise Surveys

If you’ve been issued a planning condition that requires a noise survey in accordance with BS4142, APT Sound Testing is here to assist you. We understand the growing concern among planning authorities regarding noise from industrial sites, particularly as urban redevelopment initiatives increasingly bring industrial and residential areas into closer proximity.

The push from Central Government to redevelop brownfield sites has led to a situation where industrial noise and operational hours can significantly impact the quality of life and amenity in nearby residential areas.

Local authorities often impose strict controls on noise emissions through planning conditions, making it essential to consider noise insulation measures for plant and machinery. Achieving specified sound pressure level limits, whether at the site boundary or at nearby sensitive receptors, can be crucial in complying with these conditions. As such, establishing noise level guidelines, setting limits, and monitoring compliance are key components in ensuring that noise from industrial activities does not adversely affect surrounding communities.

When a new noise source is introduced as part of your project, we can measure the existing noise levels in the area over a 24-hour period and then predict the impact of the new noise source. If the noise source is already operational, we will measure the ambient noise levels over a 24-hour period without the noise source active and then again with the noise source operational. This allows us to determine the noise impact and ensure it aligns with acceptable levels.

BS4142 is the recognized standard for assessing industrial noise in areas where residential housing is present. It involves measuring the existing background noise levels, often at different times of the day if necessary, using the LA90 metric. LA90 is the noise level that is exceeded for 90% of the measurement period and provides a reliable indication of the baseline noise environment. Our consultants are highly experienced and thoroughly familiar with the methods and requirements outlined in BS4142, ensuring that our assessments are accurate and compliant with the standard.

We offer comprehensive noise survey reports that include detailed analyses and outline possible mitigation measures. To further support these measures, we can provide noise mapping that visually demonstrates the effectiveness of proposed solutions in real-world scenarios. Our assessments cover a wide range of industrial noise sources, including extraction systems, air conditioning units, industrial machinery, refrigeration units, and general industrial building activities.

At APT Sound Testing, we utilize the latest ‘state-of-the-art’ Norsonic acoustic equipment to conduct fully compliant BS4142 industrial noise surveys.

APT Floor Plenum Testing Services

APT Sound Testing offers specialized floor plenum testing services, adhering to the “Floor Plenum Airtightness – Guidance and Testing Methodology” (BG 65/2016). Our goal is to ensure your building’s floor plenums are properly sealed, optimising energy efficiency and maintaining a comfortable environment.

Understanding Floor Plenums

A floor plenum is a void located between a building’s structural floor and a raised access floor. This space is utilized for the distribution of conditioned air to the areas above. Properly managed, the air flows from the floor plenum into the occupied zones without leaking into adjacent cavities, risers, stairwells, or other spaces. Ensuring the air flows correctly through the floor-mounted diffusers or grilles, rather than escaping through joints or gaps, is crucial for maintaining the intended air delivery and system efficiency.

Importance of Airtight Floor Plenums

An airtight floor plenum ensures that conditioned air reaches the occupied zones efficiently, providing comfort and saving energy. Leaks can lead to significant energy loss and discomfort for building occupants. Therefore, it is essential to perform thorough floor plenum testing to identify and address any air leakage issues.

Our Testing Methodology

At APT Sound Testing, we utilize a meticulous testing process involving specialised equipment. Here’s an overview of how we conduct floor plenum air tests:

1. Preparation:
   • We remove a temporary tile from the plenum and install a fan housing directly above the opening.
   • A fan is then placed into the housing, which is sealed against the floor.
   • All air handling ducts serving the test zone are turned off, isolated, and sealed to prevent air passage outside the test zone.
2. Testing Setup:
   • Another tile is replaced with a mock tile featuring a drill hole for the high-pressure tube.
   • A series of pressure readings is taken once the equipment is set up. These readings are then compared against the floor plenum air tightness specification.
3. Smoke Survey:
   • If the plenum fails the initial test, a smoke survey is conducted to identify air leakage paths.
   • The smoke survey helps pinpoint exact areas where sealing is needed.
4. Reporting:
   • A detailed report is generated, highlighting any air leakage paths found during the smoke survey. This report serves as a reference for remedial sealing works.

Ensuring Successful Testing

Our team at APT Sound Testing is committed to helping you pass your floor plenum air test on the first attempt. Here’s how we ensure success:

• Site Audit: We arrange an on-site air test site audit as soon as the floor is in place.
• Initial Testing: Conduct an initial floor plenum air test and smoke survey to assess air leakage.
• Remedial Guidance: Provide a smoke survey report to guide your sealing contractors in effectively addressing any identified leaks.

Standards and Specifications

Currently, there is no universal standard for floor plenum testing. The specifications are typically set by the project’s mechanical engineers and are often measured in litres per second per square meter (l/s/m²) at a specific pressure, such as 0.7 l/s/m² at 50 Pascals. Occasionally, the specification might be in litres per second per cubic meter (l/s/m³), in which case the volume of the plenum must be known.
