Hz Acoustic and Denmark’s new architecture policy
Hz Acoustic and Denmark’s new architecture policy – How we help shape the buildings of tomorrow. With Denmark’s new national architecture policy, the Ministry of Culture, together with the Ministry of Social Affairs and Housing and the Ministry of Rural Districts, sets a clear and ambitious direction for the future of construction. The policy acts as a guide for municipalities, developers, and professionals across the industry, and it emphasises one central point: we must build with care. At Hz Acoustic, we welcome this direction. The policy is not only an important step for Danish architecture; it also reinforces the values that have shaped our work from the beginning. Many of the dogmas now forming the foundation of Denmark’s architectural strategy are principles that have guided our development since the first Hz acoustic panel was produced. This article outlines the structure of the policy and highlights how Hz Acoustic actively contributes to three of its key dogmas. A policy that emphasises sustainability, transformation, and quality The national architecture policy focuses on strengthening the built environment across the country. It encourages more nature in cities, improved spatial planning, and better preservation of cultural heritage while promoting diverse housing solutions. At the same time, it highlights the importance of craftsmanship, material awareness, circular methods, and the need to care for buildings already in use. As Minister of Culture Jakob Engel-Schmidt puts it: “We must build with care. Every time we build, we shape not only the present, but equally the future.” This perspective aligns closely with wider international movements in architecture and construction – and with Hz Acoustic’s approach to acoustic solutions that support responsible and future-focussed building practices. Three dogmas, one shared mission Prioritise care and beauty 0 Maintain, renovate, and transform 0 Build circularly 0 The policy introduces eight dogmas for the architecture of the future. Hz Acoustic directly supports the first three: #1 Prioritise care and beauty Quality, universal design, and long-term durability A beautiful room is not only something you see. It is something you experience – through calmness, good acoustics, and materials that complement the architecture. At Hz Acoustic, we work from the principle that aesthetics and performance belong together. Our smooth, seamless acoustic ceilings are developed to integrate naturally into the architectural design rather than stand out as an added layer. They support universal design principles because they: ensure effective sound absorption for all users offer a clean, uncluttered visual expression that suits modern architecture provide durable, long-lasting solutions for private homes, commercial buildings, institutions, and public spaces Care and beauty also relate to craftsmanship. Our acoustic panels and acoustic plaster are designed with precision, thoroughly tested, and developed to deliver stable, long-term performance. This focus aligns directly with the intention of the first dogma. #2 Maintain, renovate, and transform Extend building lifespans and avoid unnecessary demolition One of the strongest messages in the policy is that demolition should be the last resort. More buildings must be preserved, transformed, and upgraded rather than replaced. Hz Acoustic’s solutions are well suited for renovation and transformation projects. Our acoustic ceilings can: be adhered directly onto existing structures upgrade the sound environment and the visual expression of older buildings with minimal intervention be repaired, refreshed, and maintained over time This approach enables significant aesthetic and acoustic improvements without unnecessary resource consumption. It is especially relevant for the types of renovation projects now prioritised at national level, including schools, cultural buildings, sports facilities, and older residential properties. #3 Build circularly Biobased materials and recycled content as a natural part of construction The policy calls for increased use of circular methods and biobased materials across the construction sector. This is fully aligned with the materials and systems developed by Hz Acoustic. Parts of our acoustic panels and acoustic plaster are made from 100% recycled textile waste, contributing to: lower CO₂ emissions reduced waste sent for incineration higher recycled content in construction projects products that support circular material flows For us, circularity is not a distant goal but an active part of our development process. We continue to increase the use of recycled materials and expand our product lines with solutions that support more sustainable building practices. Hz Acoustic’s role in the architecture of the future The new architecture policy highlights the important role that material manufacturers play in shaping the built environment. Solutions like ours are no longer optional; they are essential elements in a future-proof approach to construction where aesthetics, wellbeing, and sustainability are considered together. For us, the policy represents: confirmation of the direction we have already taken inspiration to accelerate the development of more circular materials an invitation to strengthen collaboration with architects, municipalities, and contractors Our ambition is to provide acoustic solutions that offer architectural value, technical performance, and long-term benefits for users and society. A national policy, a shared responsibility The policy underlines that the future of architecture is shaped locally – in municipalities, by advisors, and by the professionals building Denmark every day. Hz Acoustic aims to be an active partner in this process. As construction moves towards more circular, transformative, and carefully designed solutions, manufacturers must be at the forefront. That is the position we take. We continue to develop new systems, optimise our processes, and participate in dialogue about how our acoustic solutions can support the future direction of Danish architecture. The future is built now and it must be built with care The new architecture policy provides direction. We contribute with action. We are proud to deliver solutions that already support several of the most important dogmas for the architecture of tomorrow. We look forward to contributing to a more sustainable, more refined, and more future-ready built environment together with architects, advisors, and municipalities across the country.

What is acoustic plaster?
What is acoustic plaster? Acoustic plaster is a modern and effective solution for creating better sound environments in private homes, offices, and public spaces. It is a specially developed plaster applied to sound-absorbing panels, reducing echo and noise levels. The result is a comfortable acoustic experience and a surface that visually resembles a classic ceiling – but with significantly better sound comfort. Acoustic plaster: An aesthetic and effective solution for better acoustics What is acoustic plaster, and why are more and more people choosing this solution for both private homes and public buildings? In short, acoustic plaster is a specially developed surface treatment that combines acoustic performance with an aesthetically pleasing, smooth ceiling finish. At Hz Acoustic, we specialize in acoustic plaster systems that both improve the acoustic environment and highlight the architectural qualities of a space. Good acoustics are about creating a room where sound feels pleasant. This happens when noise and reverberation are absorbed rather than bouncing uncontrollably around. Acoustic plaster is an efficient way to achieve this. With Hz Acoustic’s sound-absorbing ceiling systems – where the plaster is applied to specially developed panels – echo is significantly reduced, creating a calmer and more comfortable atmosphere. In modern buildings with hard floors, large windows, and open layouts, the need for sound regulation has increased dramatically, making acoustic plaster an ideal solution. What is acoustic plaster made of, and how does it work? Acoustic plaster differs from conventional plaster in both structure and function. While regular plaster blocks sound, acoustic plaster allows sound waves to pass through the surface and be absorbed by the underlying material. This happens through tiny micro-pores in the plaster, invisible to the naked eye, but crucial for sound absorption. At Hz Acoustic, we offer several types of acoustic plaster to suit different aesthetic preferences. Our Hz Acoustic Plaster 03 is cellulose fiber-based and provides a smooth, uniform surface reminiscent of a classic white ceiling. In contrast, our Hz Acoustic Plaster 09 is made from recycled textile waste. This version does not produce a completely smooth appearance but instead creates a structured, homogeneous surface – a deliberate aesthetic choice in many architectural designs. When our trained partners/installers apply acoustic plaster to ceilings, they do so with precision and craftsmanship. The surface appears smooth and uniform, without visible joints, perforations, or transitions, while maintaining its ability to significantly improve acoustics. This combination of functionality and aesthetics makes acoustic plaster a preferred choice in architect-designed homes, design houses, and renovation projects. The difference between Hz Acoustic Plaster 03 and Hz Acoustic Plaster 09 Choosing between the two types of acoustic plaster primarily depends on aesthetics and material preference.Hz Acoustic Plaster 03 is ideal if you want a completely smooth, minimalist ceiling with a clean, uninterrupted surface.Hz Acoustic Plaster 09, on the other hand, offers a more textured and tactile expression thanks to its rough surface, while also contributing to the recycling of textile waste. Both provide effective sound regulation, but the visual expression in the room varies depending on which type you choose. Hz Acoustic Plaster 03 Hz Acoustic Plaster 09 A ceiling without compromise Where many traditional acoustic solutions – such as perforated gypsum or wood wool panels often appear technical and visually dominant, acoustic plaster is a discreet alternative. It creates the look of a classic gypsum ceiling, but without its limitations. Visually, it appears as a smooth, uninterrupted surface that brings calm and depth to the room. In this way, the ceiling becomes an aesthetic element in the interior design rather than a necessity to be hidden. Acoustic plaster is also a craft, and the result depends on several factors: the right tools, the installer’s experience, the lighting conditions, and the building’s orientation. In rooms with large window sections or light from multiple angles, a slight shimmer on the surface may occasionally occur. This is not a defect but an optical phenomenon created by the interplay between light and surface texture. Therefore, factors such as light direction and ceiling placement should be considered during design and planning. Fine finishing with Hz Acoustic Plaster 03 In rooms with significant natural light, for example, where windows extend all the way to the ceiling, it can be beneficial to apply an additional fine surface treatment. At Hz Acoustic, we offer a fine surface coating using Hz Acoustic Plaster 03. This is a thin, final layer applied with a hopper spray after the first plaster has been sanded. The result is an ultra-fine surface that feels like the smoothest sandpaper: even, matte, and uniform. This technique is also used when refreshing older acoustic plaster ceilings that have been in use for many years. Typically, after 8-10 years, a new application of acoustic plaster can rejuvenate the ceiling without affecting its acoustic properties. This makes acoustic plaster a sustainable solution that is not only functional and beautiful today but can also be renewed and adapted to future needs.

Which acoustic ceiling is best?
Which acoustic ceiling is best? We’ll guide you to the right solution and explain why Hz Acoustic delivers the best choice when aesthetics and acoustics must go hand in hand. The best acoustic ceiling combines aesthetics and function Which acoustic ceiling is best? That’s a question many people ask themselves when faced with choosing the right solution for their home, office, or any other space where both aesthetics and sound quality matter.The short answer? The best acoustic ceiling is one that combines great acoustics with a beautiful visual appearance and that’s exactly why acoustic ceilings from Hz Acoustic are the ideal choice.

For many, it’s about finding a solution that improves acoustics without compromising the room’s visual impression. That’s why we at Hz Acoustic specialize in smooth, seamless ceilings without visible joints. A smooth acoustic ceiling that looks like gypsum but performs better The dream of a smooth, white ceiling is widespread. Many people imagine a classic gypsum ceiling that fits perfectly into the modern Scandinavian style with clean lines and a bright, minimalistic look. But gypsum has one major drawback: it is acoustically inefficient. This means that sound is reflected back into the room, creating an unpleasant and echoing soundscape. Hz Acoustic stands out by combining the best of both worlds: the smooth, visual appearance of gypsum with the superior acoustic performance of our various acoustic panels. What is the best acoustic ceiling for your project? So, what is the best acoustic ceiling? The answer depends largely on your needs. If you want a ceiling that not only absorbs sound but also creates a uniform and elegant finish without visible seams, our solutions are the right choice. We offer acoustic systems where all joints between panels are filled, and the entire ceiling surface is finished with plaster. This results in a visually cohesive and beautifully aesthetic ceiling. The acoustics are significantly improved, and you avoid compromise. Flexible acoustic ceilings with many possibilities Another great advantage of Hz Acoustic is the flexibility of our solutions. Want a white ceiling? We can, of course, provide that. Prefer a colored ceiling that complements your interior or supports your company’s visual identity? No problem. Our acoustic plaster can be tinted to achieve precisely the tone you dream of, without affecting the acoustic performance. This gives you the freedom to design the space exactly as you wish, with a ceiling that is both functional and personal. Our systems also make it easy to integrate technical features. Spotlights, light tracks, access panels, curtain rails, and speakers can all be built in seamlessly, ensuring a cohesive and elegant result. You avoid visible transitions or modifications because everything is considered from the start. This attention to detail is key when you want a truly refined finish. Maintenance and transformation of your acoustic ceiling Many people also ask: what happens if the ceiling gets damaged? Here again, Hz Acoustic stands out from many other solutions. Our ceilings can be repaired and without leaving visible marks. This means you don’t need to worry if damage occurs or technical adjustments need to be made. There’s no need to replaster the entire surface, only the affected area. The result remains flawless and uniform. If you’re considering changing your interior design or color scheme later on, our acoustic ceilings can also be transformed. You can refresh the look by changing color or texture without having to remove the existing ceiling. This makes our solutions both flexible and a future-proof investment.

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.
