ALUCODUAL® is a pre-coated engineered solid sheet comprising 2/3 layers of laminated aluminium skins. This ensures superior flatness, which is challenging to achieve with standard post-coated solid sheets.
ALUCODUAL® PANELS are 2.5 mm thick aluminium sheets that comprises of two 1.25 mm 5005 Series Marine Grade Aluminium alloy sheets, bonded together. The panels are pre-finished, and coil coated using an in-line, 3-coat fluorocarbon PVDF system. The rear aluminium sheet face has a polyester-based service coat. Product identification including the product name, colour and production date can be located on the rear of the panel. Length (mm): 3500 (ex-stock), up to 6000 (indent) Width (mm): 1500 (ex-stock), 1250 (indent) and 1575 (indent).
The panels are generally fabricated and installed as part of a rain screen, cladding system for residential and commercial projects. Following the use as an external cladding system or other, the aluminium material can be recycled.
When installed within a rainscreen cladding installation the cladding panels and supporting components must be sufficient to resist any loads imposed on the cladding system. Examples of the typical types of loads applied to the cladding system would include but are not limited to, selfweight, wind loading, & seismic loading. Alucodual cladding panels form part of a rainscreen system are not intended to function as a primary structural element.
B2.3.1 “Building elements must, with only normal maintenance, continue to satisfy the performance requirements of this code for the lesser of the specified intended life of the building, if stated, or:” (b) “15 years”
Alucodual is classified as Class A2-s1, d0 according to BS EN 13501-1 and is therefore defined as a material of limited combustibility. The rail system is composed entirely of aluminium or stainless steel and is therefore defined as a non-combustible material. Based on the above, the Alucodual cladding system can be considered compliant with clauses C3.5 and C3.7 for use as a wall cladding material.
Similar aluminium sheet cladding products (Alucobond), have been tested to the AS/NZS 4284 standard which includes water penetration testing. During testing, the test assembly was subject to two water penetration tests. The first, a static water penetration test whereby the tested system was subject to a positive static wind pressure of 750 Pa. The second test was conducted under a cyclic wind loading condition with pressures between 750 Pa and 1500 Pa. In all instances the test report notes that “no water penetration” was observed during testing. Although testing was undertaken on a different product by the same manufacturer, the rail attachment system and detailing are essentially identical to the proposed system, therefore the Alucodual system is expected to perform in a similar manner
Where adverse micro climatic conditions apply (refer to paragraph 4.2.4 of NZS 3604:2011). Note: In industrial or agriculturally contaminated atmospheres, corrosive environments and geothermal hot spots, specific design is required.
Expected life of maintained panels has an expected serviceable life greater than 15 years in Exposure Zones B, C and D ( refer NZS 3604:2011) Please note: Beach front areas with rough seas and surf beaches may have a higher corrosivity and can be defined as category E of AS/NZS 2728 and C5 of ISO 9223.
System componentry materials in accordance with Table 20 of Acceptable Solution E2/AS1 and section 4 NZS 3604:2011 and Table 1 of Acceptable Solution B2/AS1.
Where the ALUCODUAL® Cladding System abuts other cladding systems, the designer must detail the junction to meet their own requirements and the performance requirements of the New Zealand Building Code.
The handling, fabricating and installation of ALUCODUAL® and the associated accessories must be in accordance with the Installation, Design Guides in conjunction with the work safe guidelines refer to www.worksafe.govt.nz
Ensure that the primary structure complies with the New Zealand Building Code or where the designer has established that the existing structure is suitable for the intended building work.
The panel is considered a non-combustible panel and need not be separated from flues, and chimneys. However, when used in conjunction with, or attached to heat sensitive materials, the heat sensitive material must be separated from fireplaces, heating appliances, flues and chimneys in accordance with the requirements of New Zealand Building Code Acceptable Solutions C/AS2, Paragraph 7.5.9 for the protection of combustible materials.
An inspection of ALUCODUAL® panel installations should be undertaken at least annually to determine the condition of the product. Items to be checked include, but are not limited to: Exterior
Dirt - any accumulation of dirt should be washed from the surface of the panels.
Scratches and Dents - these need to be identified and repaired or the panels are replaced.
Joint Sealant - identify any failures and repair.
PRODUCT IDENTIFICATION INCLUDING THE PRODUCT NAME, COLOUR AND PRODUCTION DATE CAN BE LOCATED ON THE REAR OF THE PANEL.
This product has no warnings associated with it.
