Size an opening.
Start from the airflow you need. Enter it with the pressure drop and face velocity you can allow, and see which louvres suit and how big the opening has to be. Add your opening size to check which louvres work in it.
Estimates only. Contact Invicta for an accurate calculation and the correct louvre for your job.
Sized per opening to whichever limit needs more face area, pressure drop or face velocity, at ρ 1.2 kg/m³. The square panel is a way of picturing the size, not a recommendation: any opening at or above the face area will do the job, whatever its proportions. Preliminary sizing only, confirm project figures with Invicta.
Start from the opening you have. Enter the width, height and wind speed, read the airflow, and compare the pressure drop of every louvre in it.
Estimates only. Contact Invicta for an accurate calculation and the correct louvre for your job.
Airflow is the same whichever louvre goes in: it is the opening times the wind speed. The louvre changes the pressure drop, compared below. Per AS 4740:2025 at ρ 1.2 kg/m³.

“Couldn't speak higher of the guys. They came in early, straight onto the job, and set the expectation high from day one. That's why the package kept growing right through to close. The boys pretty much covered every square metre of this building, and they did such a good job.”
