RHEINZINK America, Inc. has introduced AIR-Z®, an optimized structured mat for RHEINZINK standing seam roof systems. Made of continuous nylon filaments fused at their intersections, AIR-Z provides the ventilation and drainage needed for a long service life.

AIR-Z is laid on large areas of underlay with substructures of wooden sheathing or derived timber products and is particularly suited for low-pitched metal roofs. AIR-Z offers excellent durability, is easy to install and provides continuous air or water flow even under high loads.

AIR-Z satisfies the criteria on "hard roofing" as per DIN 4102 when used in combination with bituminous underlayment.
