What is Air Tightness / Permeability Testing ?
Air tightness testing is one of the methods used in determining how energy efficient a dwelling it. Air tightness testing is conducted to make an air permeability assessment. ‘Air Pressure Test’ and ‘Air Permeability Test’ are two other names for ‘Air Tightness Test’. It must be noted that leakage of air causes loss of heat and renders a building inefficient. According to the Part L of the Building Regulations, fresh buildings must pass the air permeability test to ensure that they are energy efficient. It is a requirement of Part L1A of the building regulations. A draughty building requires more energy to heat and causes discomfort for the occupants. An air permeability test is used to establish the rate of air leakage from a building which must meet the standard defined in the building regulations. The test also shows the leakage points in the building which helps to take remedial action.
