Architectural Acoustics Ascendancy: Introducing Ruukki® Sono

Ruukki Construction, part of SSAB’s sustainable steel-based portfolio, has unveiled a breakthrough in building acoustics, the Ruukki® Sono acoustic partition wall. Specifically engineered for industrial & office use, this advanced wall element represents a marriage of aesthetic finesse, acoustic performance & environmental mindfulness. As part of the Ruukki® Sound Environment family, the product is tailored to meet the rising demand for acoustic comfort in modern spaces.

Decibel-Diminishing Design: Mastering Soundscapes Indoors

The primary allure of Ruukki® Sono lies in its superior sound absorption capabilities. With an absorption coefficient (αw) of 0.90, classified under Absorption Class A, the element drastically diminishes ambient noise, echoes, & reverberations. This acoustical aptitude is achieved through a carefully engineered perforation pattern & a premium mineral wool core. The end result is a serene interior environment, ideal for productivity & concentration in bustling office settings or dynamic industrial halls.

Fireproof Fortification Features: Safety Also Serenity

Beyond acoustic efficacy, the Ruukki® Sono element boasts outstanding fire resistance (EI30), a rarity among perforated acoustic panels. Its high-quality mineral wool core not only absorbs sound but also impedes fire spread, offering an invaluable dual-purpose solution. It achieves airborne sound insulation at Rw 32 dB, effectively mitigating unwanted sound transmission between interior spaces.

Modular Marvels & Multifunctionality: Flexibility in Form

The panel’s intelligent modular design enhances its utility. Measuring 1200 mm in standard width, it can be split into two 600 mm modules for versatile installation options. Whether placed horizontally or vertically, the wall element integrates seamlessly into both new builds & renovation projects. Furthermore, it shares the same joint design as Ruukki’s existing sandwich panels, allowing straightforward compatibility in complex construction plans.

Chromatic Customisation & Creative Control: A Designer’s Delight

Architects & builders can enjoy wide aesthetic latitude thanks to the panel’s color-coated steel exteriors, available in standard as well as custom color palettes. This chromatic adaptability ensures that acoustic functionality doesn’t compromise on visual appeal. From muted corporate tones to vibrant creative workspaces, the Ruukki® Sono can be tailored to fit diverse architectural vocabularies.

Sustainable Scandinavian Sophistication: Green Goals Aligned

Manufactured at Ruukki’s eco-conscious Alajärvi facility in Finland, the acoustic wall element reflects the brand’s commitment to reducing environmental impact. It is crafted using sustainable processes, aligning also with the broader ESG ambitions of SSAB. The product embodies Ruukki’s vision of harmonizing client needs with climate targets through smarter, greener construction innovations.

Echo-Erasing Expansion: Rolling Out Across Regions

The product’s commercial debut is set for June 2025 in Finland, followed by a phased rollout across Nordic & Baltic countries. By addressing the dual demands of sound comfort & fire safety in one solution, Ruukki aims to capture a significant share in the acoustic construction segment. The strategic expansion highlights the growing relevance of sound-conscious architecture in high-occupancy indoor environments.

Client-Centric Craftsmanship: Voices from Ruukki

Speaking on the launch, Jani Backlund, Business Director, Building Envelopes Finland, said, “Acoustics are a key part of the user experience in buildings. Ruukki® Sono enables the creation of quieter, more focused spaces without compromising on safety or budget.” Esa Lehtimäki, Portfolio Manager, added, “It exemplifies how we translate customer insights & sustainability goals into tangible, high-performing solutions.”
