Reducing Heat Build Up In Your Roof Space

Keeping your home cool indoors when its hot outside can be a problem. With the intense Australian sun beating down on your roof it can cause temperatures to reach uncomfortable levels within the house. This can be alleviated by air conditioning but this is often expensive in terms of running costs.

In summer this trapped air gets hotter and hotter, the roof space ends up becoming a ‘sauna’, conversely in winter a build up of cold air will mean more heating and can result in damaging condensation which can create mould if the roofspace is not correctly ventilated. An unventilated roof space in summer means you are paying electricity costs to cool your home, while allowing your closed up ‘oven’ roof space to get hotter and hotter.

How a well ventilated roof space can help…

Approximately 1/3 of unwanted heat that builds up in your home comes in through the roof. With traditional roofing materials such as tiles and metals this is hard to control without resorting to an expensive solution that may involve complicated structural changes. At Pure Ventilation our answer is a roof ventilation kit. These are relatively inexpensive and can dramatically reduce the temperature of your roof space.

“The most effective method to cool your home is to keep the heat from building up in the first place, a good starting point is the roof space!”

Our kits are designed for a range of different sized roof spaces with options including duct to a vent or roof cowl (both metal and tiled roofs). The kits comprise of an inline fanwhich mechanically pulls the warm air from the roofspace and exhausts it to the outside. You also have passive vents strategically positioned to allow fresh air to enter the roofspace. This cross flow of ventilation principle will result in a lower ambient temperature, the roofspace will no longer be like a sauna!

Furthermore with our roof ventilation kits you can select if you wish to have the kit suitable for hard wiring with a temperature controlled thermostat, or for DIY installation meaning the fan comes with a flex and plug. The thermostat means the fan will kick in when the roofspace reaches a certain temperature, whereas the plug option can be wired to a switch or possibly plugged into a 24 hour timer.

In summary reducing roof space heat buildup prevents trapped hot air from warming ceilings and radiating back into your living areas – installing a system like ours will make air conditioning systems more efficient during the summer and in warm climates.
