APT Sound Testing offers comprehensive Air Tightness Testing services across the United Kingdom. Our expertise covers a wide spectrum of projects, ranging from individual dwellings to large-scale commercial structures. With UKAS accreditation for both Air and Sound testing, we ensure compliance with Building Regulations and Standards. This unique accreditation enables us to conduct Air, Sound, and Vent Testing in a single visit, providing clients with cost-effective solutions and streamlined on-site coordination, without the need for subcontracting.

Air Tightness Testing
Air Tightness Testing, mandated by Building Regulations Part L in 2006 for England and Wales, is instrumental in fostering environmentally sustainable buildings by curbing energy wastage through air leakage. Defined as the uncontrolled flow of air through building gaps and cracks, air leakage, commonly recognized as draughts, contributes to energy inefficiency. The resultant energy loss, termed the building emission rate, necessitates adherence to specific testing and emission rate criteria, such as the standard dwelling target of 5.0m3/hr/m2 and even lower rates for commercial buildings, typically around 3.0m3/hr/m2.

Air Infiltration and Exfiltration
Addressing air infiltration and exfiltration is pivotal, as these phenomena can lead to adverse consequences such as condensation, mould, and structural damage. At APT Sound Testing, we offer consultancy and design reviews to guide clients from project inception to pre-completion testing, facilitating building control signoff. Our flexible testing schedule, including weekends, minimizes disruptions during regular working hours.

APT Combined Air &Sound Testing Packages
Furthermore, our combined Air and Sound testing packages deliver significant cost savings and operational efficiency. Leveraging our engineers’ multi-skilled expertise and UKAS accreditation, we offer a streamlined ‘3-step’ pre-completion package, eliminating the need for multiple contractors. On-site coordination is optimized, with both tests conducted methodically on the same day, while out-of-hours testing options further mitigate disruptions.

We pride ourselves on providing expert advice and support to help properties achieve requisite emission rates for air testing. Clients can easily reach out to our knowledgeable team of air tightness consultants through our contact form or by contacting our offices directly. At APT Sound Testing, we are committed to delivering reliable, friendly service tailored to meet your specific air testing needs.
