At Hz Acoustic, we create good acoustic­s, and for us, good acoustics is not just a question of sound. It is a question of quality of life. It impacts us when sound becomes noise, whether it’s at home in the kitchen or in the meeting room at work­, where sound is bounced around on hard surfaces. That’s why we created Hz Acoustic.

Our unique acoustic plaster systems have eminent noise-reducing­ properties. At the same time, they are completely joint-free­ and seamless. The result is beautiful, smooth surfaces – with virtually no loss of ceiling height.

They can be installed on most surfaces and blend in discreetly, preserving architectural lines and meeting wishes, whether in private buildings, homes, offices or other places with less than good acoustics.­

We pride ourselves on combining aesthetics, engineering and acoustics.


Sustainability is an integral part of Hz Acoustic’s DNA. All ceilings are made of recycled materials and are primarily produced in Frederikshavn. The systems are VOC-free products, using up to 94% recycled material and are up tp 100% recyclable.

If damage or discolouration occurs, the surface can be carefully repaired on site without replacing the entire surface. It is a repair that completely preserves the acoustic effect without it being visible afterwards. It makes sense – both economically and environmentally. The products are highly competitive in terms of price, and some solutions cost the same as an ordinary plaster ceiling with felt.

The ceiling of the future is made of milk cartons

Our latest addition is a sustainable acoustic ceiling made from paper remnants from milk cartons.
