Air leaks lead to higher energy consumption and often cause problems with the ventilation system. Air leaks can also lead to condensation in the construction[,] which in its turn can cause a poor indoor climate.
To detect air leaks with a thermal imaging camera a temperature difference and a pressure difference is needed.
With a thermal imaging camera you detect the characteristic patterns that occur when cold air is coming through a leak in the construction, goes along a surface and cools the surface down. The thermal inspection should always take place on the side of the construction with negative pressure. Air leaks are often detected with the help of the pressurization method, often referred to as the “BlowerDoor” test.
