Altus® Window Systems

Altus may be a relatively new name but our heritage stretches back over fifty years in New Zealand. We are one of the pioneers for the introduction of Aluminium within the NZ windows and doors market.

Back in the 1950's Aluminium was almost an unknown material, not like today, where it is used in a wide range of industries and applications. Over the years there have been a number of name changes since the company started trading in Wiri, 1961. Alcan commenced operations in Australasia in 1936 and was part of a parent company based in Canada. The parent company Alcan Aluminium Ltd restructured in 1994 and sold off the shares of its Australian and NZ operations, Capral was formed as a result of these changes.

In 2002, Ron Holden, Bill Bradnam and Capral Aluminium Australia formed NALCO to take over the assets of Capral Aluminium NZ Ltd in a joint venture. In 2006, Ron and Bill purchased Capral’s remaining shareholding to become the outright owners of NALCO.

In 2016 NALCO™ and Fletcher Building formed a joint venture called Altus NZ Limited. This partnership brought with it the combined strength of six fabricator brands; Bradnam's™, Fisher™, Nebulite™, Nulook™, Rylock™ and Vistalite™. And a volume of product brands including dual GLAZE™ & Stellar Doors™ and patents.

Today Altus is a leading designer of Aluminium window and door systems for both residential and commercial sectors through innovative and ground breaking research.

Aluminium is one of the lightest commercially available metals. Key benefits include:

• Density about one third that of steel or copper
• Excellent strength to weight ratio
• Good corrosion resistance, with the option to anodise or powder coat for greater protection
• Thermal (heat) conductivity
• Electrical conductivity – high enough to be used as an electrical conductor (like copper)
• Economical recycling due to low melting temperatures – re-melting uses about 5% of the energy required to smelt new aluminium from its ore. We recycle 100% of our process related aluminium scrap.

At Altus, our objective is to minimise the environmental impact of our Aluminium manufacturing and operational activities.

Our Objective
To meet this objective, we have put in place a number of programmes that will deliver zero waste and zero incidents in the workplace.

Below are a number of these:

• Lean Manufacturing, which reduces waste and improves worker safety and operational performance.
• Recycling of Aluminium both at a manufacturing and Fabrication level including packaging and construction site waste.
• Gate to Gate is an Altus initiative to reduce and manage the environmental impact of aluminium throughout its journey from the NZAS gate to yours.
• Building for climate change is a partnership with MBIE (Ministry of Business, Innovation & Employment) working on reducing emissions from buildings during their construction & Operation.
• NZAS - New Zealand's Aluminium Smelter. Altus is a proud partner with Rio Tinto and the NZAS Aluminium Smelter in Bluff, New Zealand. NZAS produces some of the world’s cleanest aluminium.

Lean Manufacturing
The Principle of lean manufacturing, which forms part of our overall strategy is:

• To avoid creating waste wherever possible.
• To recycle waste products where avoidance is not practicable.
• Preference for suppliers who adopt similar green policies.
• Reduce our energy use wherever possible.
• Use zero or low VOC (volatile organic compounds) products wherever possible.
• The promotion of green principles within the organization and to all stakeholders.
• To provide a healthy and safe workplace for all staff.
• To choose workplace environments that have been designed with green principles.
• To do our best to reduce the environmental impact of our existence for the benefit of all stakeholders and our community

Recycling of Aluminium
Aluminium can be recycled indefinitely as reprocessing does not damage its structure.

Aluminium is also the most cost-effective material to recycle. Reprocessing the scrap uses about 5% of the electricity needed to produce the original primary aluminium and its CO2 emissions footprint is significantly smaller. This makes aluminium a very successful and environmentally friendly recycled product. By recycling your aluminium you will reduce your cost of waste to landfills and ensure that an important resource is not wasted.

Scrap aluminium from manufacturing, building demolition, and market collections achieves high sale values and is readily purchased, making aluminium one of the most successfully recycled products used in the construction industry.

Gate to Gate
Gate to Gate is an Altus initiative to reduce and manage the environmental impact of the aluminium throughout its journey from the NZAS gate to yours.

This includes Transportation, Manufacturing, Packaging, Fabrication and Recycling of any off-cut metal. We are working with our trusted partners to ensure the very best outcomes for Home Owners and for the New Zealand environment.

Building for climate change
With guidance from MBIE (Ministry of Business, Innovation & Employment) Altus are working on reducing emissions from buildings during their construction and operation, while also preparing buildings to withstand changes in the climate.

NZAS - New Zealand's Aluminium Smelter
In addition to our work with Gate to Gate, Lean Manufacturing and working with MBIE, Altus is a proud partner with Rio Tinto and the NZAS Aluminium Smelter in Bluff, New Zealand.

NZAS produces some of the world’s cleanest aluminium at approx. 2Mt CO2-e/t Al, compared to China which is predominately coal @ ~18t/CO2 per t/Al.
