How do Roof ventilators work? Well that is a really good question. The objective of a roof ventilator is to move the heated stale air from the roofspace but how?
There are many roof ventilators that just sit on the roof and really do nothing whether they spin around or not, some work some don’t. Quite often manufacturers of these products totally misunderstand the concept for harnessing the elements for natural ventilation – with roof ventilation you can have too much or not enough the wrong kind or two different kinds that do not work well together.
THE OBJECTIVE FOR EFFECTIVE ROOFSPACE VENTILATION IS TO MOVE THE AMBIENT AIR THROUGHOUT THE ROOFSPACE
This will replace the heated air with constant fresh ambient air, in turn cooling your home in summer and keeping the roofspace dry from condensation and/or humidity moisture 24/7 365 days a year. So for natural ventilation to harness the principles of fluid dynamics you will need an inlet and an outlet ventilator for each zone of your roof.
Furthermore you will need to have a design element within the ventilator to harness all the principles of fluid dynamics – convection – the venturi effect and wind driven airflows. With all these characteristics you will surely have an excellent roof ventilation system for your roofspace.
Universal Tile Ventilators and Smoothline Ventilator systems have inlets and outlets within the roof and design elements within the ventilator to harness all the principles of fluid dynamics. Not only that they are designed aerodynamically to take all Mother Nature has to throw at them.
