AIR-Z is laid on large areas of underlay (e.g. made of bitumen) with substructures of wooden sheathing or derived timber (e.g. Oriented Strand Board).

The main field of application is low-pitched metal roofs with pitches ranging between 3 and 15° or non-ventilated roof coverings and roof systems with a substructure consisting of derived timber products over the entire surface. AIR-Z compensates for substructure tolerances (up to approx. 2 mm) and nail marks and improves the slide property of long sections. A further advantage over simple bitumen roof sheeting with an inlay of glass fibre is the improvement in reduction of the sound transmission resulting from rain, which can be as much as 9 dB (A) depending on the construction. Reliable Protection from a single Source Opting for a roof made of RHEINZINK always represents a decision for quality at the same time.

The perfectly coordinated system structure made up of the AIR-Z structured mat or the VAPOZINC structured underlay and a RHEINZINK standing seam covering offers you reliable protection from a single source. Experience through Invention RHEINZINK is considered to be the inventor of the structured mat. It was developed by our engineers over 18 years ago as the sustainable and dependable solution to the problem of how to reliably protect the substructure of roofs covered with RHEINZINK from waterlogging and how to minimise noise.

Since then millions of square metres have been successfully installed and ensure optimum moisture compensation. With AIR-Z and VAPOZINC we can now offer you two products which are perfectly tailored to our standing seam-roof systems.
