Interlocking Panels – V25

ZINC, COPPER, ALUMINIUM, COLORBOND, CORTEN & STAINLESS STEEL

INTERLOCKING PANELS FOR CLADDING & SOFFIT

Interlocking Panel System or V25 is an elegant system with smooth contemporary profile design. It is often used on a modern architectural projects because of its dramatic express joints and flat appearance that creates sleek and clean looking facades.

Interlocking Panel system is suitable for wall cladding and soffit only. With its vast tray widths and flexible express joins, it offers an opportunity to design individual and varied wall solutions.

INTERLOCKING PANEL SYSTEM BUILDUP

Standard panel widths are 190 mm, 290 mm or 390mm depending on material and thickness. However the panels can also be manufactured in various widths giving a modern random effect. Three panels in varying width are quite fashionable at present. We do not recommend panels wider than 390mm as this will result in thermal distortion and “Oil Canning”.

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

INSTALLATION

Depending on the material and thickness, maximum panel size can be from 6 meters for zinc, copper and aluminium to 9 meters for colorbond, stainless steel and corten. Top hat substructure (usually 1.15 mm thick galvanized) fixed at a maximum of 600 mm centres.

We recommend installing a “breathable vapour” membrane behind the top-hat substructure to act as a second line of defence to stop any water ingress as well as allowing the building to “breathe”. Flashings associated with the installation are fixed in the traditional concealed method with allowance for thermal expansion.

FEATURES & BENEFITS

Provides a smooth looking system, flat appearance with negative details.

Natural ventilated air flow.

Solid panel design, installed directly on to a galvanised top hat and fixed directly onto the structural element of the building.

Fully waterproof without the use of exposed mastics and sealants. It is classified as a rain screen system allowing water to flow without entering the aluminium, zinc, corten, and copper wall panel structure.

Flexibility in overall appearance of the system as joints can vary from 0 – 18mm. The panels are adaptable in width to exactly fit the opening.

Economical as it creates minimum wastage of materials.

OUR EXPERTISE

We work closely with architects during the design stages to share our expertise on installation and technical details. From traditional to contemporary applications, our aluminium, zinc and copper roofing and cladding solutions are specified based on their durable, sustainable and virtually maintenance-free nature that need to withstand the elements and protect those within. Being corrosion resistant, non-combustible, architecturally appealing, their outstanding list of benefits just can’t be beaten.

VMZINC

Composed of very high quality zinc (at least 99% pure) alloyed with copper and titanium to make it harder and stronger, increasing both mechanical and creep resistance.

Lifespan of 50–80 years, depending on exact location.

Continues to develop a natural protective layer (or patina) as it ages, self-repairing any marks and scratches throughout its lifetime.

COPPER

Lifespan of 70­­–100 years, depending on exact location.
As a result of surface oxidisation caused by weathering, copper forms a protective barrier (patina) that resists further corrosion and extends its life.
This results in ongoing colour changes depending on the environment – from blue-green to nut-brown.

ALUMINIUM

Superior quality aluminium, produced In Europe and available for use in all our panel systems.
Lifespan of 40–60 years, depending on exact location.
Pre-painted using a PVDF paint system, using at least two layers to produce a minimum paint thickness of 27 microns.
Can be used in areas without direct rainfall with no corroding or discolouring.

COLORBOND

Manufactured in Australia to Australian Standards (AS1397 and AS/NZS 2728) and tested in some of the harshest Australian conditions over the last 50 years, genuine COLORBOND® steel is far more than just ‘paint on steel’.

The COLORBOND® steel range has been developed to give great design versatility and to suit a wide range of environments. And the new COLORBOND® steel Matt range of colours create a softer, more subtle look that is both understated and contemporary.

The steel base is manufactured to meet relevant Australian Standards, ensuring strict adherence to the required grade and strength.

CORTEN

Often called “weathering steel”, Corten steel panels form a stable rust-like appearance if exposed to the weather for several years.
This protective surface layer, or patina, is produced by Corten’s metal panel chemical composition and produces anti-corrosive properties superior to many other structural steels.

Natural ventilated air flow. It is classified as a rain screen system allowing water to flow without entering the aluminium, zinc, corten, and copper wall panel structure.

Metal cladding/roofing and especially lengthy flat-span sheet-metal panels often will exhibit waviness, commonly referred to as “oil-canning.” The degree of oil-canning and the appearance of the panels will vary depending on factors such as the length and colour of the panels, alloy, gauge, substrate condition and exposure to sunlight. Oil-canning pertains to aesthetics and not the performance of the panels and is not controlled by the contractor. The type of metal roofing panels specified can affect the degree of oil-canning. Roofing Group is not responsible for oil-canning or aesthetics. Oil-canning shall not be grounds to withhold payment or reject panels of the type specified.
