The Challenge

Because active and inactive areas frequently exist within the same louver bank, there is most likely ductwork on the backside of a portion of the louver. Inactive louvers can be a detriment to mechanicals for a host of reasons:

  • • Air penetration
  • • Water penetration
  • • Fire breach
  • • Weather breach
  • • Wet zone breach during installation

The Solution

Designers frequently need more louvered space, but when airflow is not required through 100% of it, blank-off is a great solution. Blank-offs protect the inactive louvers in several ways:

  • • Insulated
  • • Moisture resistant
  • • Fire retardant
  • • Weather-sealed
  • • Interior-facing
  • • Fully sealed system that allows for installation without breaching the wet zone


Our professionals look at every louver and blank-off project through a custom lens. Not only will our team work with you to engineer the best possible solution, but we'll test every system before its' installed to ensure its performance.
