Importance of Ventilation to Combat Moisture

For any enclosed space, ventilation is important particularly if you will be spending hours inside it. Sheds are no different. To ensure health and safety to the occupants of your shed, it should have good, well-planned ventilation.

There are various reasons as to why ventilation is important and one of them is to prevent mould. Aside from being a danger to your health, it could also affect and damage materials in the shed. Moisture can also affect the building itself.

According to the Australian Health Protection Principal Committee (AHPPC) advises that improved ventilation may limit the spread of certain respiratory diseases, such as COVID-19 in indoor environments. 

Also, the  National Construction Code (NCC) 2019 introduced new provisions to help minimize the health impacts resulting from condensation within houses and apartments and some sheds are used as houses

And why is ventilation important?

With air circulating around the room, it would help keep the mould from breaking into your house. Having good and proper ventilation could reduce the condensation so the mould cannot grow. 

High levels of internal water vapour passing into wall spaces can also cause condensation in walls. And the insufficient ability for the wall to dry, due to entrapment of moisture from a lack of vapour permeability in outer materials in predominantly cooler climates and or a lack of wall cavity ventilation is the primary cause of condensation in walls. 

Having a ventilated space would also help get rid of the excess heat during summer. Excessive heat inside the shed can be uncomfortable and could also damage some materials your store in your sheds, such as paint or gasoline.
