Many metal window systems look identical once installed.
But what they're made from can define their environmental impact for decades.
If the magnet doesn't stick, your windows are aluminium - and they already have end-of-life value.

Aluminium plays a unique role in the transition to a circular built environment.
Unlike many construction materials, it can be recovered, remelted and reused repeatedly without loss of strength, durability or performance.
As part of Hydro, TECHNAL enables circular renovation by keeping aluminium within the construction industry - not downcycled or lost to landfill - and transforming it into new high-performance aluminium window, door and facade systems.
ONE SIMPLE TEST.

FROM END-OF-LIFE TO NEW PRODUCTSTECHNAL supports the recovery of end-of-life aluminium windows, doors and facades and reintroduces that material into new architectural systems manufactured using Hydro CIRCAL® aluminium. This closed-loop process reduces embodied carbon, preserves material value and supports ESG and net-zero ambitions - without compromising design or performance. |
Circular renovation demands more than recyclable materials.
It requires early engagement, proven processes and full traceability.
TECHNAL offers a uniquely integrated approach - from take-back to replacement - backed by Hydro's aluminium expertise and UK-based recycling infrastructure.
Closed-loop aluminium take-back
End-of-life aluminium is recovered, processed and remanufactured entirely within the construction sector - closing the loop from old to new.
Designed for Circularity
TECHNAL window, door and facade systems are designed for disassembly, recovery and long service life, supporting circular renovation from the earliest design stage.
Low-carbon aluminium
New products are supplied using Hydro CIRCAL® aluminium, made with a minimum of 75% post-consumer recycled content and independently verified.
Architectural performance without compromise
From windows and doors to curtain walling and sliding systems, TECHNAL delivers high-performance, design freedom and long-term durability.
Discover how TECHNAL supports circular renovation - from recovering end-of-life aluminium to delivering new TECHNAL high-performance aluminium window, door and facade systems.
This short video explains how early engagement, careful dismantling and closed-loop recycling help reduce waste, lower embodied carbon and protect long-term building value.
Tell us about your project and discover how TECHNAL can support circular take-back and replacement - from first conversation to final installation.
Existing aluminium building systems are assessed early in the project to confirm content, condition and approximate volume.
Early engagement is critical to determine whether circular take-back is feasible.
End-of-life aluminium systems are carefully dismantled rather than demolished, preserving material quality. Aluminium is collected on site and kept separate from other waste streams.
Recovered post-consumer aluminium is sorted, shredded and remelted within Hydro's recycling network, then recast into new low-carbon aluminium billets for use in building systems.
The recycled aluminium is reintroduced into new TECHNAL windows, doors and facades - closing the loop by turning end-of-life systems into the next generation of architectural solutions.
