ROOF VENTILATION AND SKY TUBES
Why roof ventilation is important to drive heat and moisture out of your roof cavity all year round, keeping you cooler in summer, and protecting your roof space during cooler winter months.
Wind vents will typically move 85-100m³ of air per hour (air extraction typical of a 250mm diameter product), they are quite inefficient. This level of air extraction is similar to taking a tile off your roof and covering it with a static cap. Yes, 1-4 wind-vents will still impact your home, but to achieve good results you should look at 3 air changes per hour (5 is even better). On that calculation most homes should have 6-8 wind vents, while a single Solar Star will exceed that level of ventilation even on a cloudy day. The cost of installing 3 quality wind vents equates to one Solar Star.
There are many performance claims made on the market, but solar powered roof ventilation is going to make a substantial difference compared to wind vents. What are the most important things you need to review when purchasing roof ventilation?
The best way to know if you are getting value is understanding the wattage of the solar panel and the diameter of the extraction fan. While there are other variables this will provide you with the simplest and easy way of working out whats best for you.
