The galvanised steel vents are not suitable for installation in a coastal environment. For coastal environments, please use the 316 marine grade stainless steel vents, or alternatively our round 316 marine grade stainless steel eave vents available here.

October 2024: Please see our new Australian Made Bush Fire Rated Eave Vents which are a vastly superior product. We recommend them in all cases over this existing product.

June 2023: Factory Second 316 marine grade stainless steel vents available.

The manufacturer has released a new stainless steel version of the eave vents for coastal areas. Unfortunately the first shipment wasn't up to the standard that we expect, so they have agreed to let us sell them as factory seconds. We have reduced the price by 40% to match the galvanised steel vents. This offer is only while stock from the first shipment lasts.

Functionally there is nothing wrong with the vents. What can you expect:

A slight bend in the metal vent from the manufacturing process punching repeated holes into the metal sheet. This issue is minor as installation and fixing (with six screws in the marked locations) will correct the bend.
Some imperfections in the paint. This may include small patches of thin paintwork (generally only in one area on one side of the vent, but may be on both sides) or some contamination underneath the paint when viewed up close (see photos). This issue is cosmetic only and does not affect the performance of the vents. It is unlikely that you would be able to see it or discern the flaw once the vents have been installed.
An off-centred template. Some of the vents have been manufactured with all of the holes punched about 3mm off centre. This issue is minor and again cosmetic only. It is unlikely that you would be able to see it or discern the flaw once the vents have been installed.

Description

Bush fire rated eave vents are unobtrusive and easy to install. They are covered in white powder coating.

Improve your roof space ventilation by allowing air to freely enter the roof space. If you have a whirlybird, you can substantially increase its performance and maximise its efficiency by allowing replacement air to freely enter the roof space.

We recommend four to eight eave vents per home for maximum roof space ventilation.
