Air Tightness testing is compulsory in Scotland under Section 6 of the Building Regulations (Scotland). More information on the newest update of Section 6 of the Building Regulations can be found on our dedicated Section 6 Guide. In England and Wales, Part L1A of Building Regulations sets the requirements for Air Tightness testing in new buildings.
RMP consultants are members of Elmhurst Airtightness Scheme (EAS) – formerly known as the Independent Air Tightness Testing Scheme (iATS) – and they regularly undertake air tightness testing for a variety of clients, for domestic and non-domestic buildings.
Since December 2007, Robin Mackenzie Partnership and Building Test Services Ltd in Devon embarked on a new partnership offering combined air tightness and pre-completion sound insulation testing. Phil Wright of the Building Test Services is a fully accredited member of the Air Tightness Testing & Measurement Association (ATTMA).
Air leakage can contribute to up to 10% of heat loss in buildings as well as occupants dissatisfaction. Gaps and cracks in the building envelope are often difficult to detect by visual inspection, as they can be obscured by internal building finishes or external cladding. The alternative method is to proceed to a non-invasive Air Tightness Test to measure leakiness of the building fabric as a whole.
Air tightness testing involves connecting a fan or a number of fans to a doorway or another suitable aperture in the building envelope. Air volume flow through the fan and the building pressure differential inside and outside are recorded. A relationship between air flow and pressure differentials allows to then calculate the leakiness of the building envelope.
