What is leakage?
Leakage is some time referred as airtightness. Leakage can be defined as less resistance of air from some point. In the buildings, the leakage is caused by difference of pressure between portions. This difference is also effected by outside environment.

How does it effect?
Air tightness is the basis requirement during construction of any building. It helps in maintenance of temperature, humidity and pressure. Airtight buildings provide many positive contribution to the people inside such as
Air tightness is the basis requirement during construction of any building. It helps in maintenance of temperature, humidity and pressure. Airtight buildings provide many positive contribution to the people inside such as
- It decreases bill of heating or cooling due to low leakage resulting less consumption of equipments
- Quick achievement of desired temperature
It is experimentally proved that with the control over leakage, significant energy can be prevented from loss. This help in low capacity heating and cooling system due to Les requirement. Because the system will have less load on it which help in proper working of thermostat function.
The main points where leakage take place are
- Wall-wall joint
- Windows frame-wall joint
- Doors-wall joint
- Floor-wall joint
- Window sill-wall joint
- Window lintel-wall joint
- Inclined roof-wall joint
In most countries such as United Kingdom, France, Denmark, Ireland and other countries have made regulations for air tightness test for some specific type of buildings. Similarly United States also had standard for building air tightness.
