Hi, I’m Glenn and I’ve been installing roofing vents for over 10 years. The first thing to know is both the whirlybird and the solar vents will remove the Heat. On a 35 degrees day when I walk onto a roof and cut a hole, well the amount of heat that comes out is like a hair dryer, but the question is, what will works better! The whirlybird? Or the Solar vent?
There strengths! Whirlybirds will works best on a windy day and the solar vents will work best on full sun which is on the hottest days.
Whirlybird Roof Vents
Advantages for the Whirlybirds
The Whirlybird will work 24 hours a Day and the solar ventilation will only work 10 hours per day.
The Edmond’s Whirlybird comes with a 15 year warranty and solar vents only has a 5 year warranty.
A Whirlybird will only cost you one third of the price as a solar vent.
Whirlybirds don’t make any noise! Unless there 20 years old and need to be replaced.
Whirlybirds come in a range of colours, solar vents only come in Black.
You will save money on the cost of air conditioning.
Disadvantages with the whirlybirds
Whirlybirds need wind to work better and remove more heat
Only takes out 300 to 500 cmh of air (Eco solar vent will take out 2800 cmh)
300 s/m roof you need 3 whirlybirds but only 1 solar vent (less holes)
