A look at the unique production and testing – ensuring quality, strength, durability, and light weight performance.
In achieving a high performing façade with Vitracore G2, adequate quality controls as well as leading edge production facilities are critical to success.
The production facilities that manufacture Vitracore G2,
The factory used to produce the Vitracore G2 is also independently assessed and audited by CodeMark to ensure the systems Fairview and its manufacturers have in place are adequately geared to produce a quality product.
Fairview’s Vitracore G2 has been engineered to offer the highest in performance in areas including flatness, resistance to out of plane buckling, rigidity, resistance to compressive loads, lamination strength and weight advantage over other façade products.
These advantages are thanks to the core of the G2 – made from a profiles 3mm core, expanded to 2.8mm and working together with the skins like a honeycomb structure to increase strength while keeping the weight down.
To create this high-performance façade, an advanced manufacturing process is used to create each component in the make-up of the G2, then combine the four elements in a banded laminate structure that enables the G2 to offer a high performing façade solution that meets and exceeds all Australian building requirements.
What makes up Vitracore G2?
Components of Vitracore G2 include:
Manufacturing Vitracore G2 is a careful engineering process to assemble the components of the G2 into a bonded laminate façade that yields outstanding performance.
Vitracore G2 is manufactured using a continuous lamination process where the three aluminium layers (face skin, profiled core, and rear skin) are bonded together into a complete panel. This enables a precise and durable façade product. The rigidity of Vitracore G2 alleviates oil canning and panel deflection, proving it to be an exceptionally durable façade product for decades to come.
The stages of manufacturing include:
1.Dow Bynel adhesion film:
The adhesive used to bond the three aluminium layers is extruded in a thin film with an overall thickness of 0.04mm. This is cooled, trimmed to width then rolled onto a core ready to be applied.
Vitracore G2 Extrusion Process
During the extrusion process, quality control checks are performed to ensure that the film is uniform in consistency and thickness.

2. Application of Dow Bynel film:
Prior to the manufacture of G2, the film is applied to the surfaces of the three aluminium components. The film is applied to the underside of the face and rear skins as well as both sides of the core.
During the lamination process, heat and pressure is applied to activate the bond. Given the pressure and nature of the profiled core this creates very slight variations in the thickness of the film in the finished panels but does not affect the overall consistency of the adhesive film.
Vitracore Adhesive Application to Aluminium Coil
Overall, two layers of Dow Bynel film is used with a total thickness of 0.16mm, which represents 8% of the allowable thickness as stipulated in the National Construction Code.
3. Assembly of the G2 panel:
Vitracore G2 is manufactured using a continuous lamination process where the three aluminium layers (face skin, profiled core, and rear skin) are bonded together into a complete panel using a pre-applied Dow Bynel adhesive film (hot melt glue).
Vitracore G2 Manufacturing Process
To ensure a quality product, batch testing is conducted with each production of Vitracore G2. Through each production run, at each 200mt of produced stock, a sample is cut for testing to check:
-The Peel is carried out at the time of installation, then at the 2-, 4- and 6-week mark post manufacture.
-In between the test intervals, the sample is left outside, exposed to the elements, tested regularly, and cycled through hot and cold.

Ongoing Quality Control and Testing
360 VIEW is the highly unique, quality control process Fairview developed to govern our rigorous approach to design and sourcing, material testing, regulatory compliance, and product warranty.
Our Total Quality Control process starts and ends with customer satisfaction: your satisfaction governs how we think, act, and deliver from the design shop to the fabrication floor and from customer relations to product sureties.
Vitracore G2’s Independent Testing and Auditing
Vitracore G2 is manufactured in carefully quality controlled and regularly audited factories. This auditing has been undertaken under three separate product and quality control schemes:
Fairview guarantees that any Vitracore G2 being supplied to the market is 100% consistent with what has been tested and certified as compliant with the BCA (Building Code of Australia).
Fairview and affiliates have taken and are continuing to take actions to prove the consistency, reliability, and performance of G2. These include (but are not limited to):
The result of this production process, coupled to strict testing ensures a quality product free from defects and one that will last for the design life of the building.
No other external façade product has had the same level engineering, testing, and compliance assessment as Fairview’s Vitracore G2.
Vitracore G2 is the perfect engineered solution for any cladding application.
Fairview takes a whole of industry approach, and to that end we maintain a sharp focus on education and resource sharing as the industry continues to steady itself. We engage with a range of experts from fire specialists to technologists and bring that knowledge back to the industry to benefit us all.
