Azenco’s R-Blade adjustable-roof pergola can be equipped with an automated louvered roof system that uses sensors to determine when to open or close: a wind sensor for strong winds, a rain sensor, and a temperature sensor in case of snow or frost conditions. The roof is made with twin-wall aluminum louvers to achieve strong sealing and resistance, and the posts feature an invisible gutter system to keep the area under the roof dry.
