R P Air Testing Ltd provide a complete compliance testing service for dwellings using specially designed equipment. The blower door test measures the amount of air that flows into or out of a house while maintaining a set pressure difference between the inside and and the outside of the unit under test. The equipment used to perform the test is calibrated by BSRIA to UKAS requirement, which measures airflow at a variety of pressure differences of between 100Pa and 30Pa and deliver the final rating in m3/hr/m2 at a pressure of 50Pa

The process achieves very accurate, repeatable test results to meet the requirements of Building Regulations and the relevant technical standards

Testing is performed when the building facades, external envelope and internal finishes are complete. As soon as the building gets to this stage our Engineer will prepare and test the building at a time that fits into your schedule – normally between 8.00am and 5.30pm Monday to Friday, (alternative times may be arranged where required for a small additional fee)

Don't worry if your building doesn't pass first time, when this occurs our engineer will identify areas that may be improved and will then wait while the remedial works take place. The test will then be repeated until a satisfactory result is achieved

All of our measuring equipment used to carry out tests are calibrated to UKAS requirements by BSRIA, UKAS Calibration Laboratory No. 0807 and copies of certificates are available on request
