Roof Whirly: What is it?

A roof whirly goes by many names, some of which you will know:

• roof mounted wind turbine ventilator
• whirly bird
• whirly twirly

Air naturally rises inside buildings, and turbines use this and any outside breezes to ventilate. RoofWhirlys4Africa turbines get placed at the roof’s highest point (apex) and they spin using wind or thermal currents to draw out stale air in the building and introduce fresh air through vents. Even minimal breezes or internal thermal currents can cause the turbine t spin, creating low-pressure zones that pull out hot air via centrifugal force. Designed for windless days, these turbines rely on thermal convection to maintain continuous ventilation and keep indoor air cool.

We look forward to welcoming you to our RoofWhirlys4Africa website where you will find our RoofWhirlys4Africa range of superior quality affordable energy saving wind turbine ventilators (roof mounted and sewer / toilet vents).

According to a ventilation expert… “I’m a big fan of turbine vents. My neighbor, at my recommendation, had two turbine vents installed when he re-roofed his house last summer. He reports that the attic is about 30° cooler post-turbine as opposed to pre-turbine. They are constantly in their attic since they store stuff up there. And in our daily sunshine here that lasts for about 11 months, his turbine vents are always spinning, with or without wind.”

With or without wind

What many seem to misunderstand is that they work with or without wind. They do not depend on wind alone in order to function.

As the air in your building heats up, the heat will rise, going through the turbine vents. The hotter the air, the faster it rises, and as it goes through the turbine vents, the turbines will spin. As they spin, they pull more air out. The hot air, the vents, and the resulting wind (or with external wind) work off of each other to create a very nice ventilation system.

Turbine roof vents are some of the best ventilation devices around

Summertime Benefits

Whirlybirds are really handy during the sweltering summer months.  As temperatures approach 40 degrees Celsius, you are probably willing to do just about anything to get some relief.   Heat rises, the heat which over the warm hours of the day continues to build and moves up into the roof cavities increasing the temperature of the entire building.   Your RoofWhirlys4Africa whirlybird type vent sucks that hot air out of the building, preventing it from radiating down into your work and living spaces.  In turn, your air conditioning system won’t have to work as hard – and your electric bill should reflect that.

Wintertime Benefits

Keeping your roof in good shape is extremely important. Roof repairs can be quite expensive; replacing an entire roof is even more so. Moisture and water damage are two of the biggest threats to a roof’s structural integrity. During the winter, moisture-laden air becomes trapped in the cavities of your roof. Mould, mildew and rot can easily develop. Over time, those forces can weaken a roof and cause significant damage. Why risk it? A whirlybird draws out that moisture-filled air, keeping your roof in tiptop shape. It’s a small investment that has major returns.

Environmental Impact

RoofWhirlys4Africa whirlybird type vents are of the variety known as passive ventilation systems.  This means they are powered by the air itself, and because of this do not use electricity, or create carbon emissions.  Our RoofWhirlys4Africa are whisper quiet – a huge advantage over most fan varieties.  These vents do the BEST job cooling buildings, which means that you will have less need to use AC (air-conditioning) units during hot weather.   This all means that their environmental impact is low.

Effectiveness

Turbines are able to move a lot of hot air. Even if there is no wind speed to drive the turbine, they still allow hot air to rise through the open flaps of the turbine.

Invest in a Whirlybird Today

In addition to providing many great heating and cooling benefits, our roof mounted wind turbine ventilators (aka whirlybirds or whirlybird vents) come in a wide range of colours. They coordinate well with any type of roof.  Furthermore, our RoofWhirlys4Africa type vents do not allow rainwater in.   As the specialist roofing experts say “Whirlybirds have no real downsides – but they have plenty of benefits and advantages.  In this day and age, finding ways to save money is important.  A whirlybird can lower your utility bills, protect the structural integrity of your roof and keep your home much cooler in the summer; invest in one today.”
