We now manufacture corrugated Colorbond Vents with removeable covers.
So that at certain seasons of the year, namely winter you can seal your vent off to prevent cold air entering your ceiling cavity.
Then in summer months you can remove the vent covers to allow air circulation.
They all come with Ember Proof mesh which you screw on when fixing vent to corrugations.
The example below is 230mm wide x 190mm high and suits horizontally orientated colorbond - colour shown in Basalt.
Other sizes and orientation are available upon request.
Available in any common colorbond colour and also zincalume steel.
