Product Details

These specially designed vents are great for underfloor, in wall and sofit ventilation of your steel building. Corro VENTS address that problem of how do we vent the structure when we have a corrugated or Custom Orb wall. They can be supplied to suit horizontal or vertically clad walls. These vents work with all standard Custom Orb and Corro profiles (not mini orb). These vent plates are available in Zincalume, Galvanised (Gal) Colorbond and Stainless Steel (call us). Vents come supplied with pop rivets and spark excluding mesh for BAL purposes and suit up to Bal 29.

Drilling Vent Holes – When installing we recommend drilling the following number of 25mm vent holes in your cladding, rather than chopping out a section this is much better for the structural integrity of your cladding.

Standard Corro Mount Vent available in the following sizes:

  • 150 x 150mm Square = 6 x holes in the pan
  • 150 x 300mm Rectangle = 12 x holes in the pan
  • 300 x 300mm Square = 22 x holes in the pan
  • 200 x 200 Square for Trimdek, Monoclad, Trimclad profiles = 8 x holes in the pan
  • 200 x 400 Rectangle for Trimdek, Monoclad, Trimclad profiles = 12 x holes in the pan

Here is a chart to help you calculate your vent requirements if you have been asked to meet a particular level of air flow capacity for your underfloor area. The first column is the airflow per vent in mm squared. The next column is the total airflow for 6 vents, then 12 vents and so on.
