Acoustic ceiling in a modern apartment in Aarhus C
Acoustic ceiling in a modern apartment in Aarhus C – Flexible acoustic panels provide peace and quiet with minimal loss of ceiling height When you build with concrete, you build strong – but the acoustics are not always ideal. That’s what Lars Mortensen, department director at Fredsted Studio A/S, noticed when he moved into his newly built apartment in Aarhus C. With large rooms, smooth surfaces, and panoramic views of the city, the setting offered modern comfort – but also echoing reverberation. The solution was an acoustic ceiling with flexible acoustic panels from Hz Acoustic. A discreet yet highly effective intervention that transformed the acoustics without disturbing the aesthetics. Acoustic ceiling with minimal loss of height The apartment ceiling is clad with Hz Flex 019 – a flexible foam panel only 20 mm thick. It was developed to create acoustic ceilings with minimal loss of ceiling height, making it ideal for modern apartments where you don’t want to compromise on vertical space. In this case, the panels were glued directly onto the existing concrete ceiling, making installation both simple and quick. Hz Flex 019 is particularly suitable for rooms with hard surfaces such as concrete, glass, and steel, where sound waves otherwise have free rein. The flexible acoustic panels significantly reduce reverberation time, creating a room that feels more comfortable to spend time in – without changing its visual expression. Smooth finish and hidden details The panels were finished with Hz Acoustic Plaster 03, resulting in a completely smooth surface without visible joints or seams. The outcome is an unbroken and elegant ceiling that fits naturally with the apartment’s modern style. An extra aesthetic feature in this project is the integrated curtain rails, running seamlessly and continuously along the walls with window sections. This creates a harmonious transition between wall and ceiling while keeping the panoramic view over Aarhus as the natural focal point. As Lars himself puts it: “It was important to me that the ceiling didn’t draw attention. I wanted to improve the acoustics without compromising the architectural expression – and it has worked perfectly.” A discreet solution with great impact An acoustic ceiling doesn’t have to make noise – visually or practically. With the right solution, aesthetics and function can work hand in hand. In this apartment, Hz Flex 019 and Hz Acoustic Plaster 03 have created a ceiling that both reduces noise and enhances the room’s qualities. Dreaming of calm and quiet without compromising on design? Then flexible acoustic panels and an acoustic ceiling with minimal height loss are the way forward. Contact one of our installers to learn how we can tailor the solution to your home.

Good acoustics at the Workers’ Museum in Copenhagen
Good acoustics at the Workers’ Museum in Copenhagen This article was written by Frank Ulstrup for Byggematerialer.dk, issue no. 116 (November 24, 2022). In 2015, Hz Acoustic ApS set out to develop high-quality acoustic systems that everyone could afford. Today, the company supplies solutions for everything from private homes to Christiansborg Palace – including the Workers’ Museum in Copenhagen. Since 1879, the former meeting hall of the labor movement – now the Workers’ Museum on Rømersgade – has echoed with workers’ songs and rousing speeches. But it’s unlikely that the acoustics ever sounded as good as they do today, following a comprehensive restoration of the museum’s central rooms. In addition to fresh paint and a new lighting and climate control system, several of the spaces have now 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 has more than 20 years of experience working with acoustic solutions but only founded Hz Acoustic seven years ago. Since then, he and his team have been dedicated to developing products that surpass the existing options 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.

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.
Elegant acoustic ceiling in the iconic Vipp Chimney House
Elegant acoustic ceiling in the iconic Vipp Chimney House In the heart of Nordhavn’s industrial charm lies an architectural gem with a remarkable history. Vipp Chimney House, built in 1902 as a water pumping station and reborn as a design icon, now serves as an exclusive guesthouse that unites industrial expression with modern luxury. Behind the transformation stands Studio David Thulstrup, who, with respect for the building’s original character, has created a complete living experience where design and function go hand in hand. For this unique project, we delivered a custom acoustic solution with a focus on both aesthetics and acoustic comfort. An acoustic ceiling that matches the architecture of the space In a room with 8.5-meter-high ceilings and an open view to the chimney through a large skylight, more than beautiful materials are needed. The sound environment must support the overall sense of calm and balance – especially in a home that is meant to feel both exclusive and relaxed. That’s why the choice fell on our Hz Basic 007 acoustic panels, combined with Hz Acoustic Plaster 03, which together create a smooth acoustic ceiling without visible joints or seams. Hz Basic 007 is a 49 mm acoustic panel made of mineral wool (40 mm) laminated with 9 mm glass granulate, glued directly onto a solid surface and then finished with Hz Acoustic Plaster 03.The panel is particularly suitable for projects that call for a robust, fully glued solution with high sound absorption and a smooth, uniform surface. The result is a visual calm that complements the house’s stringent aesthetics while ensuring a pleasant acoustic experience in the large, open spaces. The smooth ceiling enhances the overall architectural composition, where materials such as steel, terrazzo, and glass meet in a clean, cohesive expression. As part of the discreet and integrated design, built-in curtain rails have also been incorporated into the ceilings, elegantly blending into the overall look. Design and acoustics in perfect harmony Hz Basic 007 provides high acoustic comfort in a solid and stable construction. The solution is ideal for projects such as Vipp Chimney House, where maximum comfort and function are required without compromising the architectural vision. With the high ceilings and hard surfaces, the space could easily have been affected by echo and poor acoustics, but with the right acoustic panel and our fine plaster finish, the sound environment is now balanced and unobtrusive. When entering Vipp Chimney House, one immediately senses the special atmosphere – a balance between the raw industrial aesthetic and the warmth of a home. Everything is carefully curated: from the curved steel-framed doors and custom terrazzo floors to the artworks and Vipp products. In this context, our acoustic ceiling plays an invisible yet essential role. It supports the purity of the design and allows guests to enjoy the rooms without noise disturbance – whether preparing food in the open kitchen or relaxing on the sofa with a view of the old chimney. Vipp describes their guesthouses as design experiences you can check into – and that is especially true for Vipp Chimney House. It’s not just a place to stay; it’s a complete experience where architecture, materials, and atmosphere merge into one. With our smooth acoustic ceiling, we’ve helped make that vision possible.
