When initially presented with the architectural drawings, Spectrum recognised that significant savings in production cost and installation could be achieved by changing the specified materials for louvres, balustrades, and privacy screens. Following discussions with the architects and main contractor, the new solution was adopted and went on to satisfy one of Kainga Ora’s ‘Outcomes Framework – Quality and Affordable’, and the Ministry's priority focus on innovation using new approaches, systems, products and materials.

Spectrum’s modular design system and utilisation of aluminium rather than steel meant that not only would production be faster and more cost efficient, but downstream benefits in logistics and installation would also be possible.

Completed in 2020, the Porchester Road build includes 24 one-bedroom and 12 two-bedroom apartments. The complex is a modern contemporary design featuring multiple colours, textures, and low maintenance materials to ensure long term durability. Spectrum’s Clearspan Inline Fin Balustrade System and Clearspan Ali Sheet were powder coated in standard Duralloy colours to complement the building's modern palette and finishes. Spectrum’s own in-house CNC sheet router was utilised to cut the Clearspan Ali Sheet and the infill pattern supplied by the architects.

Providing a unique look with a modern twist, the Clearspan Inline Fin balustrade uses vertical fins rather than square balusters for a more contemporary finish. In this situation they were face fixed and when combined with Spectrum’s router cut aluminium panels the result was as aesthetically pleasing as it was effective. Installation was made safer and easier due to the reduced weight of the panels and balustrade compared with the original specified product in steel.

Also used in the building’s stairwells, the Clearspan Inline Fin balustrade and handrails lead down to secure gated access ways providing residents with an additional level of security. Using this product throughout the complex resulted in excellent continuity in design whilst maintaining all requirements of the brief and will continue to look good for many years. During installation particular care was required to ensure full compliance with fire regulations was adhered to, and the use additional angled extrusions and fire-retardant sealants made this possible.

Spectrum’s Clearspan Inline Fin balustrade complies with NZ building regulations and is suitable for A, B, E, and C3 applications. The balustrade is manufactured from locally extruded aluminium and to ensure maximum product longevity all fixings are high grade 316 stainless steel.
