SOLEAL Next: Sustainable Aluminium Windows and Doors for Modern Architecture

As the construction industry in the UK and Ireland moves toward low-carbon, high-performance building solutions, TECHNAL introduces SOLEAL Next - a new generation of aluminium windows and doors designed for circularity, efficiency, and architectural freedom. Combining refined aesthetics with advanced thermal and acoustic performance, SOLEAL Next is manufactured with Hydro CIRCAL® 75R as standard, an aluminium alloy with a minimum of 75% post-consumer recycled content. With 95% recyclability at end-of-life, common components for streamlined fabrication, and compliance with the latest building standards, this system enables architects, contractors and fabricators to deliver projects that meet design ambitions and environmental targets.

Versatile Design meets Practical Efficiency

TECHNAL's SOLEAL Next range offers architects and specifiers endless design possibilities with profiles in 65mm and 75mm modules, multiple opening options, and elegant, minimalist lines. The system also features common components across the window and door suites, reducing the number of items fabricators need to store. This streamlined approach makes fabrication faster, easier, and more cost-effective, helping partners deliver projects on time and within budget.

Performance that Delivers Comfort

SOLEAL Next achieves exceptional thermal performance with Uw values as low as 0.71 W/m²K, reducing energy consumption for heating and cooling. Acoustic insulation of up to 47dB ensures quiet interiors, even in busy urban environments. Optional features such as motorised locks, smart sensors and glass Juilet guarding enhance user comfort and safety.

Driving Circularity and Sustainability

SOLEAL Next is made using Hydro CIRCAL® 75R as standard, an aluminium alloy with a minimum of 75% post-consumer recycled content, reducing CO²e emissions by over 80% when compared to the European average. For specialist projects where environmental performance is critical, the system can also be specified in Hydro CIRCAL® 100R, made from 100% recycled post-consumer aluminium, delivering one of the lowest embodied carbon levels available on the market, 0.5kg CO² per kg of aluminium.

Combined with 95% recyclability at end-of-life, SOLEAL Next supports the circular economy and helps projects achieve leading sustainability certifications such as BREEAM, LEED, and WELL. With a footprint of just 1.9kg CO²e per kg of aluminium, this system enables architects and developers to meet stringent net-zero targets without compromising on design or performance.

Why Choose SOLEAL Next for UK and Ireland Projects?

SOLEAL Next is designed to meet the demands of modern construction across the UK and Ireland. Fully compliant with UK Building Regulations and the Future Home Standard, it is ideal for commercial, residential, and mixed-use developments. The system supports architectural sustainability targets and embraces circular design principles, helping projects achieve low-carbon goals. For fabricators, SOLEAL Next offers a practical advantage with common components across windows and doors, reducing storage requirements and enabling faster, more efficient fabrication.
