How to Pass an Air Tightness Test
An Air Tightness Test (also known as Air Leakage Test, Air Pressure Test, Air Permeability Test) is a government-controlled test to ensure buildings do not leak or hold too much air. Air leakage increases heat loss and if air cannot move freely enough, mould, rot, damp and condensation can be dangerous for occupants.
