BSRIA IS AN ATTMA Approved Training Partner

Airtightness is the measure of how much air leakage there is from a building. This is determined by carrying out an airtightness test and the figure obtained from the testing is the air permeability value.

Air leakage can be measured by pressurising or depressurising the building to see how much air flows in or out of the building at a given pressure. Air tightness tests are useful to architects, building services designers, energy assessors, builders, services installers, fire sealers, airtightness testers, building controllers, building owners/occupiers etc. Airtightness testing is the best way to assess the performance of the building fabric in stopping the uncontrolled passage of air. It is also a very effective method of locating air leakage paths in a completed building.

Airtightness testing is mandatory for new buildings. Testers must either be registered through a scheme such as the ATTMA scheme or iATS, or demonstrate to building control that they are competent to test and are using UKAS-calibrated equipment.

This 4-day course provides the theory behind airtightness testing as well as hands on training. It culminates in a three-part examination which, when passed, will enable delegates to begin the process of registration. The practical demonstrations and practical exam on this course are carried out using Minneapolis blower door equipment.

The course is built around the National Occupational Standards ASTATT1 to ASTATT10. These specify the standards that airtightness testers are expected to achieve in their work and hence the knowledge and skills taught on the BSRIA course. The course covers regulations and standards applicable in all parts of the UK, regardless of the location of the course.

After attending the course and passing the exams, the next step is to carry out an initial review. The cost of the initial review is included in the course fee.
