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
