FACADES WICTEC - WICTEC is an overall concept of modern-day architecture that reconciles the elements of heat storage, air conditioning, light provision and fire and noise protection within a single façade design.

Stick System Curtain Walls - WICTEC stick system facades are the flexible, tried-and-tested versatile solutions among WICONA’s range of facade systems: 

  • WICTEC 50 - is the basic version of the stick system curtain wall, with an extra-narrow face width of 50 mm, inside and outside.
  • WICTEC 60 - Featuring a 60-mm face width (inside and outside), WICTEC 60 is a stick system facade that meets the highest demands. With minor additions, WICTEC 60 fulfils the most demanding requirements with regard to burglar protection, bullet resistance and fire protection.
  • WICTEC 50HI - A passive house does not require an active heating system and therefore relies heavily on the thermal insulation and air-tightness of the facade. Based on the standard series, WICTEC 50 is certified for aluminium/glass facades suitable for passive houses.
  • WICTEC 50A - is a mounting option which makes it possible to fix the glazing on such supporting structures directly. WICTEC offers a free choice of supporting material – aluminium, steel or wood – for an identical outer appearance and glazing technology for the curtain wall.

WICTEC Unitised Curtain Walls - straight forward from planning through to completion. 

Most construction projects are subject to intense time pressure. With appropriate planning, the WICTEC unitised facade systems enable extremely straightforward processing, by means of serial production and pre-assembly of the individual facade units in the workshop. This pre-assembly process is completely unaffected by weather conditions. Consequently, this permits rapid and economical implementation for buildings of any size, whilst simultaneously enabling creative diversity and a delicate appearance. 

  • WICTEC 50EL - is a unitised version of the WICTEC 50 stick system. This range combines the advantages of the stick system structure with the assembly benefits of unitised curtain walling.
  • WICTEC EL60- is the slim version within the unitised curtain wall systems, with especially reduced sight lines of just 60 mm both inside and outside. As a result of optimised thermal insulation, the system leads the way with outstanding Ucw values of up to 0.9 W/(m²K).

Structural Glazing Facade:

  • WICTEC 50SG - A characteristic feature of WICTEC 50SG structural glazing curtain wall is the flush design with slim silicone joints between the glass panes. The system offers all-glass technology both for vertical curtain walls and sloped roof glazing.
  • WICLINE 90SG  - an all-glass integrated opening sash pursues the homogeneous full glass design with Italian style or parallel outward opening function.

We advocate for an honest and transparent conversation about the CO2 emissions

March 2024

As the world increasingly acknowledges the reality of climate change and the crucial role of sustainable practices, understanding the carbon footprint of materials, such as aluminium, becomes vital. However, when it comes to aluminium recycling, not all processes are created equal - a fact that can result in confusion and misinterpretation.

Aluminium is prized for its durability, lightness, and infinite recyclability, making it an ideal material for a circular economy. This has led to the offering of recycled aluminium as a greener alternative by many manufacturers. Nevertheless, the environmental impact of this recycling is contingent on the origin of the material and whether it has been used in a product before.

If the recycled aluminium is from used windows, doors, façades (post-consumer scrap), its CO2 footprint is close to zero, as recycling aluminium only requires 5% of the energy it takes to produce it the first time around. Post-consumed scrap is therefore the greenest recycled aluminium.
Aluminium can also be recycled from production waste, or pre-consumer scrap. As this aluminium has never been used in a product and had a useful life before, it carries with it the same CO2 footprint as the original aluminium – plus 5% from the recycling process.
Ask what’s inside your recycled aluminium

Some aluminium producers merge pre- and post-consumer scrap in their calculations, which could incentivize waste production and misrepresent high carbon footprint aluminium as zero carbon scrap. The key, then, is transparency: understanding the methods of calculation and documentation of the product you are purchasing. This allows you to get an accurate picture of the actual environmental impact of your recycled aluminium.

As a customer of recycled aluminium, you should always ask:​

What is the CO2 footprint of my product? ​
How do you calculate the CO2 footprint?​
How do you document the product you sell?



When it comes to pre-consumer scrap, however, there is an ongoing debate regarding its classification in life cycle assessment (LCA) studies. Unlike post-consumer scrap, pre-consumer scrap has never lived as a product (never consumed) and its associated CO2 emissions are fresh. Furthermore, pre-consumer scrap holds positive financial value, often being sold to external recyclers.

In addition, if your product comes with an Environmental Product Declaration (EPD) the document should describe the shares of pre- and post-consumer scrap, alongside the global warming potential (the “CO2 footprint”) and the additional environmental impacts of the product.
Two methods of calculating the carbon footprint of aluminium scrap

The confusion lies in the absence of clear guidance from international standards on the best method of carbon footprint calculation for pre-consumer scrap. There are two commonly used methods: the cut-off approach and the avoided burden approach. While both methods are valid, they deliver drastically different results.

The cut-off approach: Here, the footprint follows the main product because there is no environmental burden for the scrap.
The avoided burden approach: In this case, the footprint follows the material, with the burden shared between every output (ingot and scrap).



The main reason the two scrap types are considered equivalent is because the avoided burden approach implies the ability to fully trace the scrap. The cut-off approach, due to its simplicity, is often preferred, but it could hinder the development of the circular economy by not giving post-consumer scrap a carbon footprint advantage. This could potentially encourage the use of pre-consumer scrap, overshadowing the sustainability goal of reducing and avoiding scrap in the production process.

In light of the debate, the priority should be transparency, offering data for either calculation method. In a world that increasingly values sustainability, vague claims of being "sustainable" or "recycled" are no longer sufficient. It's imperative that we accurately define these terms, share data openly, and encourage verification.

The philosophy at Hydro Building Systems aligns with this vision. We believe that the avoided burden approach is a good way to get a realistic picture of the carbon emissions and incentivize a circular economy. We advocate for an honest and clear conversation about the CO2 emissions associated with our products. We firmly believe that through understanding, innovation, and commitment to sustainability, we can lead the way in demonstrating that recycled aluminium is not just a buzzword, but a viable, responsible choice for the future.

WICONA ACHIEVES EVEN LOWER CARBON FOOTPRINT FOR ITS ALUMINIUM BUILDING SYSTEMS

February 2024

Driving decarbonisation forward yet again, WICONA part of Hydro, has reached a new milestone for its recycled, end-of-life aluminium Hydro CIRCAL 75R, which now carries a carbon footprint of only 1.9 kg of CO2e/kg of aluminium – 78% less compared to the European average.

Originally launched in 2019, Hydro CIRCAL 75R is a prime quality recycled aluminium, made with a minimum of 75% recycled post-consumer scrap. When guaranteeing more than 75 % recycled content, WICONA exclusively refers to aluminium that has reached its end-of-life as a product-in-use and is brought back into the loop.

Using the knowledge gathered over the past few years, the Norwegian aluminium group Hydro has once again taken a step forward within recycling. Advances in sourcing, sorting and traceability of post-consumer aluminium scrap, and an optimized melting process, allows the company to deliver Hydro CIRCAL 75R with an embodied footprint of only 1.9 kg CO2e per kilo aluminium, down from the previous 2.3 kilo. The new lower carbon footprint of Hydro CIRCAL 75R recycled aluminium is documented by an Environmental Product Declaration and is available across all products of WICONA.

In addition to Hydro CIRCAL 75R, Hydro also offers Hydro CIRCAL 100R recycled aluminium which contains 100% post-consumer scrap. This special aluminium offers an even lower footprint of just 0.5 kilo CO2e per kilo aluminium. This means it is possible to specify door, window and façade profiles with a near-zero carbon footprint (scope 1, 2 and 3) – among the lowest in the world.

For now, the Hydro CIRCAL 100R is only offered for special, dedicated projects, however, thanks to advancements in technology and manufacturing process, Hydro CIRCAL 100R will progressively become more accessible as the company is focused on developing its urban mining partnerships to further enhance circularity.

WICONA's using Hydro CIRCAL recycled aluminium exemplifies the brands’ innovative spirit and commitment to anticipating specifier needs – going beyond regulations and playing a leading role in the decarbonisation of tomorrow’s buildings.

Also, WICONA enables developers and specifiers to determine the environmental impact of projects or individual products thanks to the dynamic Life Cycle Assessment (LCA) functionality via the fabricator software WICTOP by providing the actual environmental impact of the material used in its products, rather than using generic data.

Low carbon innovation and circularity is at the heart of our commercial strategy. Company-wide, we are working hard together with our suppliers and construction industry partners to find new ways of reducing carbon impact. This Hydro CIRCAL carbon footprint reduction is one initiative. We have also halved the carbon footprint of the extrusion process, compared to the European average, which will reduce the carbon footprint of our products even further. More projects are ongoing, including how our end-of-life façades will be dismantled and recycled. And we won’t stop there.
