Custom Color Qaterproof Gazebo Outdoor Garden Pergola

Aluminum Louver Pergola Roof System: Product Description PergoLam is a horizontal louver and pergola hybrid built entirely of aluminum that, when opened, lets in light and airflow. The slats are entirely sealed, preventing the passage of light and water, using a connecting system for an electric telescopic engine made of components and aluminum extrusions that have been particularly constructed. When closed, the slats transform into channels that direct water to the sides, each of which has a network of canals of its own.
