Aluminium that Performs Beyond Aesthetics

Designing for tomorrow means knowing what's behind the material. At SAPA, we create aluminium systems with industry-leading carbon transparency, certified traceability, and circular thinking built in. From curtain walling to sliding doors, every product supports your sustainability targets - without compromising performance or beauty.

Hydro CIRCAL® Explained

Hydro CIRCAL® is more than just aluminium. It's a statement of intent - towards net zero, circular construction, and fully traceable supply chains.

At the core of this innovation are two alloys:

Hydro CIRCAL® 75R This premium grade aluminium contains a minimum of 75% recycled post-consumer scrap - meaning aluminium that has already completed its life in buildings. It's not production waste. It's true circularity.

Carbon footprint: 1.9kg CO²e/kg aluminium
Fully certified by DNV-GL for content and emissions
Ideal for BREEAM, LEED and WELL certification targets

Hydro CIRCAL® 75R gives you a high-quality, durable solution at a fraction of the environmental cost. When compared with the European average for primary aluminium production, the carbon footprint is around 85% lower. It's already available as standard across all the TECHNAL UK product range.

Hydro CIRCAL® 100R The next step forward.

Hydro CIRCAL® 100R is made with 100% recycled post-consumer aluminium, offering the lowest embodied carbon available in the market for aluminium profiles.

Carbon footprint: 0.5kg CO²e/kg aluminium
Only available for selected projects where ultra-low carbon impact is a non-negotiable
Designed for projects that are pushing the boundaries of sustainable design

Hydro CIRCAL® 100R is currently in the early adoption phase, making it a powerful specification choice for zero-carbon projects.

Both Hydro CIRCAL® alloys support transparent carbon reporting, and can be used to contribute to embodied carbon assessments, life cycle analysis, and circularity targets on major frameworks.

Post-Consumer Recycling First
We prioritise aluminium that has been used and recovered from real-world applications, not just offcuts from production. Through Hydro CIRCAL®, we give end-of-life scrap a second, third, and even fourth life without degrading quality.
Design for Disassembly
Our systems are engineered to be easily dismantled, sorted and recycled at the end of their service life. Components can be separated without destructive methods, ensuring material purity and maximising reuse potential.
Verified Circularity
Hydro CIRCAL® is independently verified by DNV-GL for post-consumer content and carbon emissions. Our Environmental Product Declarations (EPDs) are public and verified, giving you full traceability and transparency. Project-specific EPD's can also be generated through our software, so you know the exact impact your choices make.

Choosing TECHNAL isn't just about meeting today's standards.

It's about designing a future where resources never go to waste.
