Acoustic ceilings at ARoS
Acoustic ceilings at ARoS – where art and acoustics go hand in hand. At ARoS Art Museum in Aarhus, architecture, art, and acoustics come together in two exceptional projects featuring world-class acoustic solutions delivered by Hz Acoustic. The new acoustic ceilings at ARoS form part of the museum’s major extension, which includes an underground gallery and The Dome, a Skyspace by James Turrell. The extension is designed by Schmidt Hammer Lassen, and contractor Aarsleff is responsible for the build. The elegant acoustic ceilings have been installed by our skilled partner, DK Akustik Vest. The project consists of two unique components: the open, atmospheric Art Square, leading visitors towards James Turrell’s artpiece The Dome, a Skyspace, and the underground Salling Gallery, a new 1,000 m² exhibition space for large-scale contemporary art. Click here to read more about the project A passage leading into the light In the new Art Square – the transitional space guiding visitors into Turrell’s iconic ‘The Dome, a Skyspace by James Turrell’ installation – light, volume, and acoustics are balanced with great care. Here, we supplied Hz Plus acoustic panels, finished with our Hz Acoustic Plaster 03 to create a smooth, seamless surface. The plaster is particularly well suited for organic and curved geometries, such as the circular skylight that brings daylight into the space and generates an almost meditative atmosphere. Along the walls, precisely fitted edge trims provide a sharp, refined finish that follows the gentle curve of the passage. The result is a calm, cohesive surface in which the ceiling becomes a natural part of the architecture, supporting the spatial experience rather than dominating it. At the same time, the acoustic ceiling ensures a pleasant sound environment, allowing visitors to move towards the artwork in quiet contemplation – fully aligned with the intention behind Turrell’s light installation. The Salling Gallery – 1,000 m² beneath the ground The second part of the project is the Salling Gallery, an underground exhibition hall of 1,000 square metres. Here, a raw, industrial concrete setting forms the backdrop for large-scale international contemporary art. For this space, we supplied Hz Dual 011-R acoustic panels, made from upcycled textile waste, together with Hz Acoustic Plaster 09, which also contains finely processed textile waste – including recycled bedsheets from a local laundry. The plaster is tinted and adjusted to match the architectural expression of the room, giving the surface depth and character without compromising sound absorption. The combination of recycled materials and advanced acoustic technology results in a ceiling that unites sustainability, function, and aesthetics – a perfect match for ARoS’ ambition to merge art and architecture. The acoustic ceiling improves the reverberation conditions in the large gallery and supports an environment where sound, light, and artistic immersion are in balance. The architecture frames the art rather than competing with it. An acoustic contribution to Danish cultural heritage With the expansion of ARoS and the opening of The Dome and the Salling Gallery, the museum adds a new chapter to the cultural landscape of Aarhus. For us at Hz Acoustic, it is a privilege to contribute to a project where sound, light, and materials are considered integral to the overall artistic experience. Whether in a light-filled passage or in a raw subterranean gallery, the project demonstrates how modern acoustic solutions can be adapted to any architectural expression – from the understated to the monumental.

Seamless acoustic ceiling in the new showroom at E. Nielsen’s Stonemasonry
Seamless acoustic ceiling in the new showroom at E. Nielsen’s Stonemasonry At E. Nielsen’s mechanical stonemasonry in Egå, a new showroom has just opened where acoustics and aesthetics go hand in hand. With this project, the long-established stonemasonry has created a space where the tactile and visual qualities of natural stone are presented in an environment that is both functional and architecturally cohesive. The ceiling solution, supplied by Hz Acoustic, ensures a seamless acoustic ceiling that does not steal attention from the impressive materials but instead enhances the overall experience. The new showroom was designed by Baks Arkitekter, who have created a holistic architectural framework with respect for the stonemasonry’s proud traditions and craftsmanship. The studio is located on the same premises, and we have also supplied a similar acoustic solution for their own offices. The close collaboration between Baks Arkitekter and Hz Acoustic is driven by a shared understanding of how materials and detailing create atmosphere and quality. A seamless acoustic ceiling with optimal sound comfort For the showroom at E. Nielsen’s mechanical stonemasonry, a combination of Hz Dual 011 acoustic panels and Hz Acoustic Plaster 09 was used. This combination was carefully selected to ensure both functionality and aesthetics. Hz Dual 011 is one of our most efficient acoustic panels in terms of sound absorption. The panels consist of 40 mm mineral wool and 9 mm glass granulate and are designed to be screwed directly into the ceiling. Each panel has four precisely positioned screw holes, finished with plugs so that the surface appears smooth and uniform. With a total thickness of 49 mm, the system achieves a very high level of sound reduction – essential in a room where stone surfaces could otherwise create harsh acoustic conditions. The surface is finished with Hz Acoustic Plaster 09, a textured plaster based on cotton waste from the textile industry. The result is a sustainable and tactile expression that appears elegant and calm. The finished ceiling surface is completely free from visible seams or joints, forming one cohesive plane that harmonizes beautifully with the room’s materials and design. A showroom with deep roots and modern ambitions E. Nielsen’s mechanical stonemasonry has a history spanning more than 225 years and is Denmark’s oldest stonemasonry. Founded in 1797, it is today run by the fourth-generation Grage family, maintaining the same dedication to quality and detail that has defined the company from the very beginning. The addition of this new showroom marks both a respect for tradition and a clear vision for the future. Natural stone is one of the most honest and durable building materials, and when presented to clients, architects, and partners, the surroundings must meet the same high standards. With our acoustic ceiling solution, we have created an environment where both the sound and character of the material can truly stand out – without acoustic challenges disrupting the experience.

Modern commercial building with seamless acoustic ceilings
Modern commercial building with seamless acoustic ceilings In the new commercial property at Rørgangen 1 in Karlslunde, functionality and aesthetics have been integrated from the very beginning. With a total floor area of over 30,000 m², including more than 3,000 m² of modern office spaces, high demands are placed on comfort, flexibility, and material quality. To ensure the optimal indoor climate and a calm visual expression, we have supplied a complete seamless acoustic ceiling solution. The project was developed by CBRE, a global player specializing in commercial and investment properties, and built by Celero, while the installation work was carried out by our skilled partner DK Akustik. The collaboration between these strong partners has resulted in a building where both the overall impression and the detailing are carefully considered. Good acoustics in meeting rooms When working with large meeting rooms, acoustics quickly become a critical factor. An unpleasant sound environment can negatively affect both concentration and well-being, especially in flexible workplaces where multiple activities take place simultaneously. For this reason, the project focused on creating a seamless acoustic ceiling that performs both technically and aesthetically. For Rørgangen 1, Hz Dual 011 was used – a specially developed acoustic panel combining 40 mm mineral wool and 9 mm glass granulate. The panels are mounted with visible screws that are later covered with matching plugs, ensuring an even and stable substrate for the final surface treatment. The finishing layer consists of Hz Acoustic Plaster 09, which contains recycled cotton waste from the textile industry. The plaster gives the ceiling a subtly textured surface, but without any visible seams or joints. The result is a smooth and homogeneous ceiling that complements the overall architecture and contributes to a harmonious atmosphere in the office space. A solution for modern workplaces The office space at Rørgangen 1 has been designed with a focus on flexibility and adaptability. The areas can easily be configured to suit each tenant’s needs, both in layout and function. Our seamless acoustic ceiling solution supports this approach by ensuring a sound environment that works equally well in open-plan offices, quiet zones, or meeting rooms. At the same time, the solution contributes to the building’s overall sustainable profile. By using materials such as textile-based acoustic plaster and high-performance mineral wool panels, the ceiling is robust, durable, and produced with environmental responsibility in mind. This makes it a strong choice – not only acoustically but also as a future-proof investment in comfort and quality. Collaboration that delivers results We greatly value our close collaboration with DK Akustik, who carried out the installation professionally and with precision throughout the office space. Together, we have created a solution that meets CBRE’s ambitions for modern, attractive office spaces while fulfilling all technical and aesthetic requirements.

Acoustic ceiling and sharp lines at Hages Badehotel
Acoustic ceiling and sharp lines at Hages Badehotel Hz Acoustic has supplied the acoustic ceilings for Hages Badehotel – a sustainable hotel development built on piles. In the peaceful coastal landscape near Rødbyhavn on the island of Lolland lies Hages Badehotel – a unique and sustainable construction created with great care for the surrounding nature. Every architectural decision has been made with respect for the environment, and the same goes for the choice of interior materials. For that reason, Hz Acoustic was chosen as the supplier of acoustic ceilings for the project. Hages Badehotel was designed by Miami Ark Architects and consists of 72 detached buildings as well as a main building housing the reception, lounge, restaurant, and bar. Everything is built on piles to protect the ground, minimize environmental impact, and create a sustainable foundation for the future. The architectural expression combines modern simplicity with functional aesthetics – and this is precisely where our acoustic panels have played a key role. An acoustic solution that matches the architectural expression When entering the buildings at Hages Badehotel, you immediately feel a sense of calm – not only because of the location but also because of the pleasant acoustics. Sound plays a vital role in the overall experience of any building, especially in spaces where guests should be able to relax, talk, or enjoy their meals in peace. Achieving this requires solutions that are both effective and aesthetically integrated. For this project, we supplied Hz Dual 011, an efficient acoustic panel made from mineral wool and glass granulate. The panel is screwed directly to the ceiling and has a total thickness of 49 mm. It is particularly well suited for buildings with large, open spaces where high sound absorption is desired without compromising on design. Together with Hz Plus 027+, a perforated gypsum panel pre-treated with acoustic felt, and a final surface coating of Hz Acoustic Plaster 03, we created a smooth, seamless acoustic ceiling that integrates naturally into the architecture. The result is a bright, homogeneous ceiling with excellent acoustic performance and no visible joints or seams. Floating ceilings and precise detailing A distinctive feature of the ceilings at Hages Badehotel is their visual lightness. This effect is achieved in part through the extensive use of custom-made edge profiles that create sharp, clean lines and precise finishes. The result is a ceiling that appears to float, supporting the light and elegant architecture. This is a detail that is not only aesthetically pleasing but also technically demanding – requiring materials and products that work perfectly together. Here, the combination of our acoustic panels and acoustic plaster once again proved its value. Acoustic ceilings in harmony with sustainability The entire Hages Badehotel project is characterized by a consistent and well-considered sustainable approach – and this extends to the choice of interior materials as well. Our acoustic ceilings contribute not only to the visual and acoustic comfort but also represent a durable solution that requires minimal maintenance. With high sound absorption, a discreet appearance, and long lifespan, Hz Acoustic acoustic panels are an ideal choice when form and function must go hand in hand in sustainable construction – even in sensitive natural areas.

Everyone has a right to good acoustics
Everyone has a right to good acoustics This article is written by Frank Ulstrup for Byggematerialer.dk nr. 116 (24. november, 2022). In 2015, Hz Acoustic ApS set out to develop high-quality acoustic systems that everyone could afford. Today, the company supplies systems for everywhere from regular homes to Christiansborg – including the Workers’ Museum in Copenhagen. Since 1879, protest songs have been sung, and countless rousing speeches have been delivered in the old assembly hall of the labor movement – now the Workers’ Museum on Rømersgade in Copenhagen. But it’s not certain that it sounded as good as it does today, now that the central parts of the building have just been restored. In addition to fresh paint and a new lighting and indoor climate system, several rooms have also been fitted with acoustic ceilings that reduce reverberation by 70-80%. A sustainable solution And that is far from insignificant when hosting fiery speeches – or, as is the case with the museum today, welcoming lively school classes, says Helge Hansen from the Frederikshavn-based company, Hz Acoustic ApS. His company provided the solution – and a solution was certainly needed: – I can hardly imagine what the acoustics were like in there before, with all those large, hard surfaces,” he says with a smile, explaining that the current solution, Hz Dual, consists of panels and plaster developed by the company itself: – At the Workers’ Museum, we have chosen an acoustic panel consisting of a mineral wool board laminated with a specially designed 10 mm waterproof glass granulate board. In addition, there is the acoustic plaster, which is made from recycled cellulose fibers and has an extremely fine surface. Together, this solution not only provides excellent acoustic properties but also creates a completely smooth surface that is very easy to repair,” he explains 20 years experience Helge Hansen explains that he has worked with acoustic solutions for more than 20 years, but it was only seven years ago that he founded Hz Acoustic. Since then, he and his team have been working to develop solutions that are not only better but also more affordable than those already on the market. And looking at the company’s reference list, it seems they have achived their goal. Numerous buildings in Norway and Germany – as well as wide range of projects in Denmark – have had their acoustics improved using various Hz systems. Better acoustics for everyone Helge Hansen points to several key factors when explaining the success: “Our goal has really been to make good acoustic solutions financially accessible to everyone, and with a price per square meter for an installed panel ranging from 500 to 1000 DKK + VAT, I think we have succeeded,” he says, continuing: “Additionally, it’s of course a sustainable product, cellulose-based, and therefore doesn’t pollute or burden the environment in the same way as, for example, quartz-based alternatives. I believe this is also one of the reasons why our products are in high demand when it comes to listed and heritage buildings,” says Helge Hansen. READ ALSO

Find an installer near you Hz Dual At the Workers’ Museum in Copenhagen, we used our Hz Dualacoustic panels together with Hz Acoustic Plaster 03.This panel was particularly well suited for the project because the building is listed. With Hz Dual, you get an acoustic solution that leaves only eight small screw holes per square meter, which means the underlying structure can be preserved – an essential requirement in protected buildings. Should the acoustic ceiling ever need to be removed, the original surfaces can be easily restored. More references See our other references here.
