Did you know that almost 1 in 2 homes will experience condensation?

Up to 40% of newly built homes in Australia experience condensation and mould-related issues because they do not allow for movement of water vapour through the building envelope (Dewsbury et al 2016).

Condensation happens when moisture laden air (high relative humidity) reaches chilled surfaces such as walls that lack insulation, sarking or single-glazed windows. Aluminum framed single glazed windows with no thermal break (common in new buildings) will form condensation due to the thermal bridge between the outdoor and indoor section of the frame acting as one piece (Bijlsma 2018).

This is most likely to occur in those parts of the home that aren’t exposed to sunlight, such as South side of the home in cool and temperate climates or areas where sunlight is blocked by excessive vegetation or neighbouring buildings. Condensation on window frames will often accumulate in the grooves of the window, and coupled with lack of air flow between windows and window treatments (curtains and blinds) and dust accumulating in the grooves will often lead to mould growth on the back of blinds or curtains.
