Top 3 ventilation options for your shed


Shed cooling

There are many decisions a shed-owner must make when designing and buying their dream shed. One important decision that can be overlooked is what to do about ventilation. That’s why we’ve put together 3 popular ventilation options with an overview of the pros and cons of each. As always, our shed design specialists are just a call away if you’d like to chat about what ventilation would be best for your shed. 

1. Rotary ventilators 

The most popular form of ventilation in Australia for the last century, rotary ventilators or “whirlybirds” are a well-known and familiar way to keep your building ventilated. Rotary ventilators use the thermal effect known as the Venturi effect, when negative pressure from inside a roof passes through the rotating blades of a whirlybird. A benefit to the whirlybird is its price tag, being one of the cheapest roof ventilation options.

There are however some drawbacks to consider. For one, there is the potential for whirlybirds to cause roof leaks if installation is not done correctly. Secondly, long term maintenance needs to be considered as moving parts (such as bearings) wear out over time. Thirdly, whirlybirds tend to ventilate only the area they are installed, requiring multiple units to avoid areas of lower ventilation. This can add to cost and risk of leaks.

2. Ridge Ventilation 

Ridge Ventilation also uses the same principles of the Venturi effect seen with whirlybirds but in a different way. A ridge ventilation system like Vent-A-Roof is a static system installed right across the top ridge of your shed. Because there are no moving parts, maintenance is not required. It is also fully compatible with the Colorbond and Zincalume roofing used by Wide Span Sheds, it is cyclone and bushfire rated, and it is more energy efficient with every 2.5 meters of Vent-A-Roof ventilating the same amount of air as 1 whirlybird.

Although upfront costs are greater than some options, there are no ongoing costs and maintenance associated with other ventilation systems. Therefore, it is a cost effective choice that many shed owners go with.

3. Powered Vents

More likely to be used in industrial buildings or factories, powered ventilation can be an effective ventilation solution. Powered Vents allow more control over air flow and can be turned on and off by a user.

The main cons to powered vents is cost, both initial setup and ongoing maintenance. Powered ventilation systems can also be loud and therefore may not be suitable for residential sheds.
