Designing with elZinc

Main features

Zinc is an excellent roofing and cladding material which will give long and almost maintenance-free service if installed properly.  Proper installation means not only the correct fixing of the zinc itself, but also the correct design and installation of the supporting structure.

In engineered façades, metal railing and point fixing systems are employed.

Single skin façade panels

elZinc® Composite material

These systems have bespoke installation solutions specially designed for the elZinc® composite material.  They are all rainscreen systems (rear vented and drained) and have open joints.

Every project is calculated according to its design wind loading which gives the maximum panel sizes possible, the panel reinforcements required (if any and depending on system) and the centres of the supporting profiles.

Hung cassettes, tongue and groove and riveted systems

Cladding zones for the different systems

Air gap

20mm minimum, some countries require more, usually up to 40mm (eg. residential projects in UK require 38mm).  The riveted system’s transoms limit the insulation depth to ≈100mm (with a 20mm air gap).

1. elZinc® hung composite cassette panel
2. Hung panel support with anti-vibration sleeve
3. Adjustable wall bracket common to all systems
4. Top hat aluminium mullion common to all systems
5. elZinc® tongue and groove composite cassette panel
6. Aluminium tongue profile
7. elZinc® riveted composite material
8. Mullion-transome bracket
9. Insulation between mullions
10. Structural support

Wall brackets

Wall brackets are adjustable.  A range of bracket depths allows for different insulation thicknesses and structure unevenness.   A thermal break can be inserted between the bracket and the wall if required.

Metal rails (mullions)

Common to all systems, made of 2,5mm thick extruded aluminium.  Fixed at centres according to wind loading.

elZinc® honeycomb panels

elZinc® panels use a specially designed point fixing system which eliminates the need for metal mullions, saving weight, costs and reducing its associated energy and CO2. The panels are installed in a typical vented and drained rainscreen configuration.  The wall brackets are adjustable in 3 dimensions to enable easy plumbing of the façade, and allow the panels to be installed in a horizontal or vertical configuration. The number of fixings required is calculated on a project by project basis, but due to the exceptional rigidity of the panel these are much fewer than on conventional systems, speeding up installation times and reducing costs.
