Blank-offs can be applied to the back of nearly any louver system to meet occupant requirements, transforming an active louver to an inactive louver as needed. Designed to fortify against water intrusion, this accessory utilizes a hydrophobic mineral wall that is flame resistant — it meets ASTM E 84 (UL 723) — and is reliably factory sealed. Additionally, the blank-off may be removed at any time to transition back to an active louver if the occupant needs change. Bird or insect screens can be added for extra protection. Blank-off panels come in a standard size range from 1" to 3" deep, but can be custom engineered based on project requirements.
