Available from Deco Australia and suitable for screens, cladding, shutters, louvres, gates, facades, and more, Decowood is claimed by the company to be 50% more durable than standard powder coating and can be relied upon for a long service life.
The beauty of aluminium is that, unlike timber, it is resistant to termite attack, and it will never warp or rot. It requires no sanding, painting, staining or oiling, and its lightweight makes it quick and easy to install.
Decowood is available in a range of batten sizes and specifiers can choose from 30 Marine Grade finishes, including Casuarina, Ironbark and Bush Cherry.
FAIRVIEW
Ceramapanel, a through-coloured compressed fibre cement panel manufactured in Europe and available in Australia from Fairview, is recommended for a range of commercial applications, including community facilities, hospitals, aged-care facilities, educational institutions, and government offices.
Available in six profiles, its multiple shades, textures, and profiles ensure plenty of scope for aesthetic expression and it is suitable for use in countless structural adaptations.

In terms of working with the product, Fairview offers installation training for all projects along with extensive technical support. Easily cut onsite, Ceramapanel cladding represents a simple installation job and requires no re-coating.
KINGSPAN
Kingspan Insulated Panels’ Karrier System and Dri-Design are designed to work together to provide a cost-effective, time-efficient, and thorough-wall solution. These building facades are weathertight, fire safety compliant, easy to install, and help designers meet their aesthetic ambitions, the company says.
Karrier System is a factory-engineered rainscreen substructure that comprises individual high-performance insulated panels designed to support the structural load of the façade. A standard Karrier panel is typically available in 1,100mm, and can be easily cut onsite making them useful for projects with various layout arrangements. Karrier panel systems are BS 8414-2 and are compliant to AS5113.
Karrier panels are made with tongue and groove joints, allowing them to fit tightly together and achieve excellent weathertightness and thermal performance, with no thermal bridges. The panels also contain a high performing proprietary insulation core (PIR) with R-Values up to 9.82 (m²K/W).
Dri-Design cassettes are installed by an interlocking system and directly fixed to a Karrier Panel’s external skin or fixed to form a ventilated cavity with a traditional construction method. Dri-Design is available flat, tapered, shadow or perforated.
Together, Karrier Panel and Dri-Design through wall system act as a single component construction method to replace several traditional components, namely weather membranes, air barriers, insulation, facade tophats, and fire walls.
MAXIPLY
Maxi Panel, a Pre-Finished Real Timber Panelling product from Maxiply, is a low VOC and non-toxic solution which celebrates the natural grain and appearance of timber.
Available in two timber finishes, Monterey Pine and Baltic Birch, the product is prefinished with a natural, hard wax oil product that is environmentally-friendly and intended to protect the timber without restricting its ability to breath. Unlike varnishes, this oil is hard wearing, won’t chip or peel, and can be repaired if damage does occur.
Maxi Panel is available in 18 standard colours, and it can also be customised (in terms of both colour and sheet size) upon request. In terms of application, both finishes are suitable for walls and ceiling linings, while the Baltic Birch finish is also suitable for joinery. The panels may be used externally in applications that are protected from the weather and out of direct sunlight.

Mitsubishi AlpolicTM NC has received an Environmental Product Declaration (EPD) from Good Environmental Choice Australia (GECA).
ROBERTSONS FACADES
Brick Inlay is an facade solution, whose manufacturing process involves embedding thin brick, porcelain, or stone into precast concrete panels. The appeal of the product is that it combines the look and feel of a traditional brick facade or wall with the efficiencies and benefits of precast concrete.
With panels delivered on site, ready for installation, construction time and cost are significantly reduced, without any negative affect on design ambition or the result. In other words, the product enables specifier to customise any pattern and texture they seek, and see the job through to completion, efficiently and cost-effectively.
In terms of site management, the comparison between Brick Inlay and traditional brickwork are stark. With no brick, sand, lime, cement and lintel storage to handle, no onsite waste to deal with, and no need for site amenities for brick laying crews, the whole job becomes significantly simpler.
Mass Timber (also known as engineered timber) is a new category of structural timber that has pushed the boundaries concerning the capabilities of timber well beyond low-rise residential construction. With its improved strength and structural properties, it is a viable alternative to concrete and steel in some commercial applications.
The production of Mass Timber involves gluing, nailing, or doweling layers of wood together to create materials that are far stronger than traditional timbers and boast an impressive weight-to-strength ratio. Available in various thicknesses, sizes, and grades, they are suitable for use as structural elements in tall structures and those with long spans.
The benefits of Mass Timber are many. They can contribute to construction flexibility, reduce labour and equipment costs, provide foundational savings, and contribute to faster completion of jobs. On top of that, the low embodied energy associated with products of this type, combined with the fact that timber is not just a replenishable resource but one that sequesters carbon from the atmosphere, make them a sustainable option.
CEMINTEL
CSR Cemintel Territory is a range of highquality, prefinished cladding panels that simulate natural materials. Achieving the looks of stone, timber, concrete, metal, tiles and smooth render with zero maintenance, the Territory suite is ideal for a variety of internal and external commercial applications.
Classified AS 5113 EW (External Walls) for fire compliance, CSR Cemintel Territory is prefinished in a variety of colours and simulated textures and available in a choice of simple aluminium or colour-matched preformed corners. Supplied with platinum coating technology to protect against UV damage and colour fade, and featuring a ventilated cavity to keep buildings dry, it can be relied upon for a long working life and minimal maintenance requirements.
