RHEINZINK® - Tile Systems

RHEINZINK®-tiles include flat-lock, square and diamond-shaped tiles.  Flat-lock tiles are primarily used for large façade surfaces. This is where their visual impact is the most impressive.

The square and diamond-shaped tiles comprise the group of RHEINZINK®-small tiles. Due to the small size of individual components, design solutions can even be found for geometrically complicated buildings. Among other things, traditional cladding of roof dormers, chimney heads or roof edges with small tiles is not a problem.

Technology

System Description

  • Diversity of façade designs using RHEINZINK®- tile systems.
  • Combination option of large and small tiles

As a rule, tiles are classified into large and small groups.  Using the flat-lock tiles (large tiles), a substantially larger surface is visible.   The square and diamond-shaped tiles fall into the small tile category.

In contrast to sheets or shingles, tiles are provided with forward-folds on their topside and fold-backs on their bottom side, so that they can be connected using the hook-in seam technique.

Tiles (large, square and diamond-shaped) can be fabricated in all variations and recommended dimensions out of panels.  They are made either manually or by machine.

Surface Quality

  • RHEINZINK® "pre-weathered blue-grey"
  • RHEINZINK® "pre-weathered graphite-grey"
  • Produced from panels
The patination process of RHEINZINK®- material can take longer in the façade area. In the transition phase, bright-rolled material has a tendency toward light reflections, which can be traced to the properties of thin sheet metal.

Thus, RHEINZINK®-façade claddings should be produced in RHEINZINK®- "pre-weathered blue-grey" or RHEINZINK® "pre-weathered graphite-grey"* surface qualities.

Furthermore, we recommend using panels for production, in order to significantly reduce wave formation, which is specific to thin sheet metal.

Surface Protection

  • Use of foiled sheeting
In order to protect the surface during production, transportation and to provide protection against negative influences during construction, the use of foiled sheeting (applied at the factory), is recommended. The self-adhesive protective sheeting should be removed directly after installation, at the end of each working day.

By fastening the tiles with clips, which are inserted and driven into the special recess provided, misalignment is prevented.


The rhombuses are fixed with bindings and inserted and attached by nailing into the therefor intended gaps.These gaps prevent tilting.

 Fixing
  • Indirect with clips on a full-surface substructure.
  • One below the other, using a hook-in seam technique
The upper tiles are hooked into the fold-back of the lower tiles, while the top is fastened to the full-surface substructure with clips.  Recesses in the fold-backs of RHEINZINK®-tiles facilitate proper positioning of the clips and prevent lateral shifting.

If fire protection requirements as per DIN 4102 are stipulated for the façade, the flat-lock (large) tiles can also be installed on a metal substructure.  Fixing, in this case, is also indirect using clips, which are riveted to the substructure.

Fasteners

  • Mainly flat headed nails or roofing felt nails
  • Blind pop rivets for metal substructures
  • Non-corrosive materials

Flat headed nails and roofing felt nails have also become the accepted fasteners for tile systems.

As a rule, blind pop rivets are the suitable fasteners for connecting cladding and metal substructures.

Fixing RHEINZINK®-flat-lock (large) and small tiles depends primarily on the type and design of the substructure.  Wind loads, as well as tile dimensions and material thickness must be considered when selecting fasteners. Please ensure that fasteners are approved by onsite building supervisors.

It is recommended that non-corrosive materials are used for application in the façade area.

Installation

  • Simple installation using hook-in seam techniques.
The tiles are interconnected via hook-in seam technology. In order to guarantee a straight line, the direction of installation must run from bottom to top. The installation direction from left to right or vice versa is decisive for the fabrication of flat-lock (large) tiles and must be considered and indicated during the design and planning phase.

Flat-lock (large) tiles can be installed horizontally and diagonally.  When installing the tiles on a cross-joint, notching the folds at the cross-joints prevents thickenings in the material. A staggered tile arrangement or mirror cladding is conceivable and can be implemented without additional expense.

The same regulations and recommendations apply to square-shaped tiles. However, the square-shaped tile can also be installed on a point.

Rounded Surfaces

  • High flexibility in rounded areas

Tiles exhibit tremendous flexibility in rounded areas. Large radii can easily be covered. For small radii, accessories should be used so that the forward- and back-folds are prevented from closing.
