These gravity-operated louvers remain open only when air flows, preventing backdrafts.

Always open, these are our most basic wall louvers.

Sized to replace block or bricks.

Designed with blades that drain water down the jambs, these louvers keep water from running down the front of the blades, even in harsh weather.

Fixed front blades give you consistent sight lines when viewing these louvers from outside, while hidden rear blades open and close.

With a gasketed sealing kit, these louvers shield your enclosure from dirt, moisture, and weather while regulating heat and stopping condensation from forming inside.
