building material

2.  Zinc is the 24th
most abundant element on earth’
 As an architectural building material, it offers an
extremely durable, corrosion resistant and easy to
maintain surface that can be used to cover and create
buildings in many ways and Zinc can be used on the
whole building envelope.

3.  They are available in form of interlocking panels.
 The panels are simply connected by the use of an
interlocking groove, giving the elegant appearance of a
recessed joint.
 They are fixed onto the framework using mechanical
fixings, which are concealed in the joint.
 The system belongs to the rainscreen sector (wall
cladding installed with a pressure equalised, ventilated
air space).
 The system can only be used on even, vertical walls.

4.  Thickness ;1mm
 Centre to centre distance; 200,250,300 mm
 Length; 0.5m ≤ L ≤ 6 m
 Width of the joint; 10 mm or 20 mm
 Slide width; 24 mm
 Weight (kg/m2 ); 11.18,10.40,9.85

5.  Metal framework:
The system can be fixed on a metal framework composed of adjustable brackets and
cladding rails made of galvanized steel or aluminium.
The brackets fixed to the structure are used to adjust the cladding rails (minimum
thickness : 2.5 mm for aluminium) which act as a support for the cladding. The
minimum support of the rails is 40 mm.
Screws (protected against corrosion) and rawl plugs are used according to the
framework manufacturer’s specification.

6.  Fixing:
Setting out, assembling the angle brackets, fixing the insulation and installing the
panels must be carried out in accordance with the appropriate manufacturer’s
recommendations.
To meet the requirements for mechanical resistance (intrinsic weight and resistance
to wind pressure), the maximum centre to centre distance between the brackets is
600 mm.
The elbow brackets are fixed in place to provide cross fixing in the longitudinal
direction of the panels.

7.  Transverse joint:
For horizontal fixing, the framework must provide a
minimum support surface of 100 mm.
 Vertical fixing:
For vertical fixing, 2 framework elements are placed at
either side of the transverse joint.
 Insulation:
The type of insulation used must comply with national
requirements if these exist, in particular with regard to
fixing and fire resistance. It must be installed according
to the fire stopping manufactures instructions.

8. Interlocking zinc wall
panels can be joined
using three
mechanical joints:
 Standing seam
 Flat lock
 Reveal
Standing

Reveal

9.  Lightweight and durable
 Fully recyclable
 A design life of 80 years
 Virtually maintenance-free
 Complex shapes can be clad using zinc cladding
facades
 All flashings and trim can be in the same material
 BRE Green Guide certified
 Available in a choice of either natural finish or 6
pre-weathered finishes
 Cost effective
 Wide range of panel types

10.  Low energy used in
the manufacturing
process
 Low corrosion, long
life
 Recycled material
 A natural material
