* Double-layer Aluminum foil makes it leak proof
* A helically shaped internal crimped galvanized steel strip locks together with the aluminum foil to form an air tight and leak proof system
* 2 stainless steel clamps assure a tight and intact seal at the venting connection for both interior and exterior helix ducting
