Each of the weather louvres have been independently tested with test results showing our range to have very low water penetration and good air flow—the equal of other locally assembled louvres. Performance information is shown in this web site via pressure drop graphs and free area charts. Drawing downloads are available on each page via a number of formats.

Extruded aluminium 6060 T5 alloy with up to 3mm wall thickness on most models.

Mill, anodised and various powdercoat finishes available.
