GAF Master Flow 18x24 Aluminum Wall Louver – Mill Finish, Flush/Recessed Mount For Attic Ventilation

About This Product

This GAF Master Flow wall louver is a simple, effective way to improve attic airflow.

It's 18 by 24 inches, made from one piece of aluminum with pre-punched vanes – so there's no separate screen to mess with.
The mill finish gives it a clean, neutral look that blends in.

You can mount it flush or recessed depending on your siding, which gives you flexibility during install.

Built tough to handle outdoor weather, and it's corrosion-resistant so it'll last.
Great for intake or exhaust in residential or light commercial HVAC setups.

Installation is straightforward whether you're building new or retrofitting.
Helps keep your attic cool and dry, which protects your roof and saves on energy costs.

Solid, no-nonsense vent that does its job quietly in the background.
