Inexpensive Roof Ventilation & Ventilators

August 18th, 2016

Roof vents really are an inexpensive option to provide ventilation to your home, kid’s cubby house, shed or beach shack.

So simple to install and cost effective roof ventilators or whirly birds as they are often called, are designed to remove hot air from a building through the roof and also to keep damp prone attic areas dry.

Roof Vents

RJ Ventilation carry a range of ventilator system options for Australian homes.

Not only are the ventilators great for reducing the hot air in a building, but the vent also helps to minimize dampness inside rooves. Ventilating living and working areas is important for your comfort and health throughout the year. Mould build up prevention is essential for those of us who have respiratory health conditions.

A ventilator system will assist you to remove a build up of hot air during summer.  In winter, ventilators will aid in reducing the impact of condensation in your roof space.

There are various types of ventilator systems available today.

There are four main types of roof ventilation products that you can use –

Static Roof Ventilation

Static vents are often called to as roof valves.

These valves sit on the roof and rely on a pressure differential between outside and inside for air to move out of the roof area.

Wind-driven Roof Ventilation

These wind driven ventilators are very popular and can be seen on the majority of homes in Western Australia. Commonly known as whirly birds, this particular design of air ventilator is a West Aussie favorite.

The whirly bird needs wind to spin the head of the vent so as to draw out the hot air of the attic space under the roof.  Good quality wind-driven ventilators have excellent bearings and start operating at low wind speeds so in WA conditions they should be spinning all of the time.

Powered Roof Vents

The powered roof ventilators are connected to your power supply and usually have a thermostat.  This unit will self start once the temperature in the roof space reaches a pre determined level on the thermostat. Air will continue to be pumped out until the thermostat goes below the temperature of the set level.

Solar Powered Roof Vents

Powered by the sun, these environment friendly ventilators also have a thermostat that triggers its operation.  As the unit is dependent on the sun for its power source it will only operate while the sun is up.

Not every house will require the exact same ventilation systems, as there are many other factors to take into consideration.

The position of your house, the nearby shrubs, bushes and trees that are close by, the materials and color of the roof, and so on. All of these factors effect the temperature inside the house.

Living in Western Australia with a diverse range of climates, it makes sense to use these simple but effective air ventilator units or “whirly birds”
