Why air leakage needs to be eliminated
Air leakage can be defined as gaps and cracks in the building fabric through which air enters or escapes. It is driven by wind pressure and temperature differences between the inside and outside of the building, therefore it is variable and uncontrollable.


Air leakage wastes energy and money. A leaky building loses a lot of heat, so the heating system has to work harder than necessary to keep the building at a comfortable temperature. This results in high heating bills and can be uncomfortable for occupants, with draughts and inconsistent temperatures. For all of us, leaky buildings mean increased emissions of carbon dioxide - the primary contributor to global warming.

The benefits of airtightness
Smaller plant and plantrooms
Reduced risk of condensation
Less degradation of the building fabric
Improved insulation
Reduced energy costs
Reduced carbon dioxide emissions
Increased occupant comfort and productivity
