Superior Construction

American Louver products are built to last. Our grilles and registers feature all aluminum construction with a meticulously engineered frame and core for extra strength. Even our newest product, Stratus™ Diffusers, are made from engineered polymers that are corrosion and mildew resistant.

Industry Leading Packaging

Nobody wins when building materials arrive at a jobsite damaged. That’s why every grille we ship is individually shrink-wrapped to keep the finish scratch-free and dust-free. We also use unique corner guards to protect against damage and a “master carton” to reduce handling costs.

In Stock and Ready to Ship

When the job needed to get done yesterday, American Louver is ready to ship today. That’s because all our products are in stock and ready to ship when the order is received. Best of all, there’s no premium charge for rush deliveries.

Easy Installation

When you save time on the jobsite you save money. For this reason, all our products are easy to install. Often times, no secondary accessories are needed, and some products, like the Stratus Diffuser, include features that make installation a breeze.
