Draft is the enemy of energy efficiency. Drafts or air leakages are year-round issues: in winter, they allow valuable warm air to escape and unwanted external cold air to enter; in summer, the reverse occurs.

Seal your building and you will save money on annual heating and cooling costs, and the size of your heating and cooling system, while improving the health and comfort of occupants.

Air leakages occur in many parts of the building envelope but we are taking a look here specifically at windows. Air leakage of windows is measured in litres of air per second per square meter of window area (L/s.m2). WERS-rated windows must satisfy Australian Standard AS 2047 'Windows in Buildings - selection and installation' which allows a maximum infiltration rate of 5.0L/s.m2 at a positive pressure difference of 75Pa but this is inadequate in cool and cold climates, particularly in high wind areas.
