Water isn’t welcome inside an insulation system, so get it out – and fast – with the help of Johns Manville’s Cross-Flo Jacketing. This new product is perfect for industrial and mechanical insulation systems, helping to expel unwanted water. Cross-Flo is a protective metal jacketing system with an embossed pattern designed to promote cross-directional flow. This provides a path for liquid that may enter the insulation system to reach the low point and exit the jacketing through a weep hole or drainage port. In fact, in testing, Cross-Flo Jacketing drained 80% faster than smooth metal jacketing after one hour! There are so many opportunities to use Cross-Flo. It is recommended for indoor or outdoor applications up to 8 feet in diameter, and can be used on all pipe as well as vertical and horizontal tanks.
