Our Aluminum Flexible Ducting is manufactured with a helically shaped internal crimped galvanized steel strip. The strip locks together the aluminum foil in order to form an air tight and leak proof lock system. It ensures excellent strength, making it perfect as a flexible solution for a broad range of venting requirements ranging from low or high pressure heating, as well as for ventilation to air conditioning applications.
It is also available with black insides to not allow light to pass through from your grow room.
