The Building Centre have announced the addition of a new corrugated roofing unit to their portfolio of products. The simple-to-install new product was designed by an experienced roofer, who was asked to solve a major roof space condensation problem in a newly constructed home. The owner did not want ugly venting objects sticking out of the roof of his new home. The installation of a number of these special units solved the problem immediately.
One has to substitute and install one to four pairs of these unobtrusive corrugated units in the roof, depending on the size of the home. Corrugated units, available from The Building Centre, are easy to install in existing, replacement or new roofs by any local roofer, builder or plumber. The result is a significantly cooler home in summer. In Winter, there will be less condensation building up, and a drier roof space is less ideal for insects to breed and live.
With no moving parts, using the ‘Convection Principle’ that ‘hot air rises’, warm air in Summer that otherwise would be trapped in the roof space, is transported out.
Sets of these ‘self venting’ roof units work on hot still summer days. With no moving parts, they are silent and unlike obtrusive motor driven vents, use no electricity.
Individuals having ducted air conditioning in their roof space can install these tiles to use less electricity, as the ducts and indoor fan coil unit will not be heated up, and will improve the air conditioner capacity and performance.
A home owner in Victoria recently installed self venting roof units as his air conditioner was not coping on hot days. Other people have advised that once self venting tiles were installed, they needed to run their system for fewer hours and their electricity bills were noticeably lower.
For corrugated roofs, based on the same principle, special ‘corrugated’ units are installed on either side under the ridge capping. These roof venting products are suitable for existing homes or when building a new home or extension. A series of ‘inlet’ and ‘outlet’ self-venting units need to be installed. The ‘inlet’ ones are located on one side under the ridge capping. The ‘outlet’ ones are located on the opposite side of the roof, again below the ridge capping. For bush fire prone areas, there are manual ‘closure caps’ available as an optional extra, to seal off the air intakes or exits to avoid sparks or embers entering. This venting system does not need wind to blow to rotate a set of blades to extract air.
When there is a breeze, the ‘Venturi Principle’ combines to draw more air out. As corrugated units are part of the roof, the roof remains waterproof. There is a commercial sized version of these corrugated units for larger applications such as storage buildings or factories.
These ‘self venting’ corrugated sheeting units are precision laser cut and quality made in Australia from durable and strong 0.55mm Bluescope Zincalume. ‘Self venting’ corrugated sheeting units have a perforated insect barrier steel to stop vermin and pests entry. To match the colour of individual roof, one can simply etch prime and paint them.
