Building Air Leakage Testing
Onsite Building Air Leakage testing is carried out in accordance with ATTMA TSL1 and TSL2 as specified in Building Regulation Approved Document L1A (residential buildings) and L2A (commercial buildings).
A typical test is carried out once the building envelope is completed. A door-mounted fan system is used to create building pressures of up to 50 Pa during which the air leakage of the building is measured.
