We use a minimum of .020-gauge aluminum for our round aluminum louvers, screens and plugs - most manufacturers use a thinner gauge, which leads to a weaker product. This thick, durable material maximizes lifespan and ensures proper ventilation needs.
Our round aluminum louver features include:
    •    Easy installation
    •    Rugged construction
    •    Sizes from 1" to 6" as well as 1.5" and 2.5"
    •    Stocked in a mill, white, black or brown finish
