Airflow is important to both the longevity and overall comfort inside of your shed. Proper airflow is required to prevent mildew and chemical fume buildup. If mildew is allowed to build this can lead to shed walls slowly rotting, stored goods to smell and grow mold and electrical equipment to degrade. Whilst fumes from chemicals such as fuels, solvents and pesticides can lead to sickness in humans and pets.
Airflow is also important for the overall comfort of your shed. Good airflow provides better temperature control and an overall drier atmosphere, making time spent inside your shed a more pleasant experience.
Shed ventilation is key to preventing these concerns especially in smaller sheds due to the lesser volume of air inside.
