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
