Sound Testing for Dwellings: Ensuring Compliance

Since July 2003, pre-completion sound testing has been a mandatory requirement under Part E of the Building Regulations. As a UKAS-accredited sound insulation testing laboratory, we offer a proactive and reliable sound testing service to help our clients achieve building control sign-off with ease.

If you’re involved in the construction or renovation of dwellings, it’s crucial to understand the importance of sound testing. Here’s what you need to know about the process and why it’s essential for your project.

What is Sound Testing for Dwellings?

A common question we receive from clients is: “What exactly is sound testing?” In simple terms, sound insulation testing assesses whether a building meets the required acoustic standards. It is a necessary process for new builds and conversions, ensuring compliance with building regulations.

To ensure accurate results, sound testing must be carried out by a qualified professional with third-party accreditation, such as a UKAS-accredited sound testing company. This guarantees that the testing process adheres to strict quality standards and provides reliable results for regulatory compliance.

Types of Sound Testing

There are two primary types of sound insulation testing:

1. Airborne Sound Insulation Testing

Airborne sound refers to noise that travels through the air and penetrates separating structures between rooms. In the case of a lightweight floor, airborne sound could pass through elements such as the plasterboard ceiling, the floor void, and the floorboards, ultimately reaching the adjacent room.

2. Impact Sound Insulation Testing

Impact sound measures the noise level in a room when a direct impact is made on the floor above. This test is particularly important in multi-story buildings, where sound transmission between floors needs to be minimized to ensure comfortable living conditions for occupants.

Regulatory Requirements and Compliance

The specific acoustic performance standards for new builds and conversions are outlined in Approved Document E: Resistance to the Passage of Sound. These regulations set the minimum requirements for sound insulation, ensuring that buildings provide adequate protection against noise transmission.

For refurbishments, the standards are slightly more lenient than for new constructions, as it is generally more challenging to retrofit effective soundproofing solutions into existing structures. However, compliance is still required to meet building control approval.

When is Sound Testing Required?

All new-build properties and conversions completed after July 2003 must undergo sound testing. A minimum of 10% of each party wall and floor construction type must be tested to ensure compliance with regulations. Testing is conducted between pairs of rooms that are separated by party walls or floors, helping to verify that noise levels remain within acceptable limits.

Optimal Environmental Conditions for Conducting Thermal Imaging on Building Envelopes

Thermal imaging (infrared surveys) has become an essential tool for assessing the condition of building envelopes. However, to consistently achieve accurate and reliable results, it’s crucial to conduct thermal imaging under the correct environmental conditions. In this article, we’ll explore the best conditions for APTs thermal imaging surveys, and how they contribute to effective building envelope assessments for BREEAM and/or building control signoff.

Understanding Thermal Imaging for Building Envelopes

When we undertake a Thermal imaging, or infrared thermography on your building, it involves capturing and analysing the infrared radiation emitted by the materials within the building envelope. When applied to building envelopes, thermal imaging can reveal temperature variations and anomalies that may indicate issues such as insulation deficiencies, air leaks, and moisture intrusion. To ensure these observations are precise, certain environmental factors must be considered and accounted for, they are:

Temperature Differences between internal and external

A significant temperature difference between the interior and exterior of the building is key to effective thermal imaging. This temperature gradient helps highlight thermal anomalies more clearly. For most accurate results, a temperature difference of at least 10°C (18°F) is recommended. Conducting thermal imaging during the early morning or late evening, when outdoor temperatures are cooler and there is less solar loading, can create the necessary contrast.

Weather Conditions on the day of the survey

Clear weather conditions are ideal for thermal imaging on the day of the survey. Avoid conducting thermal inspections during rain, snow, or heavy wind, as these conditions can affect the accuracy of the readings. Moisture from rain or snow can mask thermal patterns, while strong winds can cause rapid temperature changes that lead to inaccurate results.

Solar Radiation

For better accuracy, solar loading must be minimised whenever possible. Direct sunlight can heat building surfaces unevenly, creating false thermal patterns. It’s best to perform thermal imaging either early in the morning or late in the evening, when the sun’s impact is minimal. Alternatively, cloudy days can also provide suitable conditions, as cloud cover diffuses solar radiation and reduces its impact on the building envelope and provides better thermal images.

Surface Moisture on building envelopes

Wherever possible, ensure that the building surfaces (roof, walls and floor) are dry before conducting thermal imaging. Moisture on the surface of the building can absorb and emit infrared radiation differently, leading to misleading results. After rainfall, it’s advisable to wait until the surfaces have dried completely before performing thermal inspections.

Humidity Levels

Moderate humidity levels are preferable for thermal imaging. Extremely high humidity can cause condensation on building surfaces, affecting thermal readings. Conversely, very low humidity can lead to rapid temperature changes that may impact the accuracy of the results. Aim for humidity levels between 30% and 60% for optimal conditions for the best results.

Wind Speed

Low wind conditions are ideal for thermal imaging. Strong winds can cause rapid cooling or heating of building surfaces, making it difficult to obtain accurate temperature readings. Conduct thermal inspections during periods of calm or light winds to ensure stable and consistent thermal patterns and better accuracy.

Conclusion

Conducting thermal imaging on building envelopes under the right environmental conditions is essential for obtaining accurate and reliable results. By considering factors such as temperature differences, weather conditions, solar radiation, surface moisture, humidity levels, and wind speed, property owners and inspectors can effectively identify and address issues within building envelopes. By optimizing these conditions, thermal imaging can provide valuable insights into the health and efficiency of buildings.
