Archclad™  Express 25 mm is a clean, modern concealed-fix cladding system with an attractive recess or express joint between panels. The express joint can be adjusted to suit the application and design of the project. From as little as 5 mm to as wide as 30 mm, the joints can alter the entire appearance of a large flat expanse of metal (15 mm is recommended).

Standard panel widths are 192mm and 292mm. A 242mm panel width is available if using 1.0mm VM Zinc. However, the panels can also be manufactured in various widths giving a modern random effect. Three panels in varying widths are quite a striking design. We do not recommend panels wider than 350mm as this will result in thermal distortion and “Oil Canning”.

With all the above options, together with staggered joints or splayed applications, the Archclad™ Interlocking Express Panel 25 mm is the obvious choice for cladding where a long, thin, flat appearance is required.

Specifications

Specification

Archclad™ Express, 25 mm wall cladding, and soffit lining.

Dimensions

  • Material Thickness: 0.8 mm Aluminium, 1.0mm VM Zinc, 0.55mm Colorbond, 0.9mm Copper
  • Standard Panel Width (Centre to Centre - C.T.C.): 307 mm (292 mm panel + 15 mm joint)
  • Width of Joint: from 5 mm to 18 mm
  • Maximum Panel Length: from 0.5 m to 6 m
  • Panel Height: 25 mm
  • Cladding Zone: 28 mm

Substructure

Top Hat substructure (usually 1.15 mm thick galvanized steel subject to substructure engineering) fixed at a maximum of 600 mm centres—subject to required wind loading.

Maximum Length: 6 m due to the length of the pre-slotted fixing points and the thermal properties of the material.

Scope of use

Installation

Installation is to be carried out by a duly authorized and trained installer. All fixings are to be concealed, and tolerance for material thermal movement must be allowed during installation.

Due to the design –Archclad™ Interlocking Express- Panel 25 mm – is, in essence, a rain screen and requires diligent installation. We recommend installing a "breathable vapour" membrane behind the top-hat substructure to act as a second line of defense to stop any water ingress as well as allow the building to "breathe".

Flashings associated with the installation are available from Architectural Cladding and must be fixed in the traditional concealed method with allowance for thermal expansion.

Performance

Testing

The product has been tested in accordance with Australian Standard AS 4040.2-1992 ("Method of testing sheet roof and wall cladding for non-cyclonic regions") and has been found capable of withstanding wind pressure of 7 Kpa and therefore satisfies AS/NZS 1562.1:1992 Design & Installation of sheet roof and wall cladding - metal. Internal bracing and substructure spacing at the design stage will be required to achieve higher wind loads. For further information kindly contact us.

Testing to Australian Standards

Archclad™ Interlocking Express Panel in aluminium has also undergone structural performance tests in accordance with AS/NZS 4284:1995 "Testing of Building Facades" (test results on request).

All aluminium supplied by Archclad™ is premium European grade solid aluminium and has been tested to AS/NZS 1530.3:1999 "Method for Fire Tests on Building Materials, Components and Structures Part 3: Simultaneous Determination of Ignitability, Flame Propagation, Heat Release, and Smoke Release."

All Archclad materials are non-combustible and have been tested to AS 1530.3-1999 Method for Fire tests on Building Materials, Components and Structures Part 3: simultaneous Determination of Ignitability, Flame Propagation, Heat release, and Smoke Release.

Archclad™ have tested the Interlocking Express Panel to meet the Weatherproofing FV1.1 Assessment method by a NATA Approved Testing Facility. This weatherproofing is only achieved by using a series of sub-flashings with specific tested proprietary waterproof vapour membrane. Installation must be carried out by an experienced installer who is familiar with the methods prescribed. A quality assurance declaration will be required to be completed by the installer.
