The BHB Panel Series
Concrete core noise protection panels
Excellent acoustic performance and long lifetime
The PHONOBLOC® BHB series are concrete core panels that are established for many years on the European noise protection market because of their positive product characteristics. The many design and configuration options along with the resistance and strength of these panels are their key success factors. Due to their heavy weight, the panels are produced as close to the installation site as possible in order to save costs and reduce the impact on the environment. Optimum sound absorption and reflection coefficients are achieved by adding HB absorbers as cladding on one or both sides of the panel. The solid concrete core makes up the supporting material and absorbs airborne sound. The PHONOBLOC® BHB series – certified for 50 years lifetime in accordance with EN 14389-1/2.
Advantages of the BHB Panel Series


The BHB panel has been designed and tested to withstand the toughest climatic conditions for more than 50 years.
The optimum sound insulation is ensured by the massive concrete core of the panel.
The dovetail recess of the wood concrete absorbers enables an everlasting compound with the concrete base layer.
Our PHONOBLOC® HB absorbers offer a variety of different surface structures and colour options.
PHONOBLOC® BHB panels are fully CE-certified and tested in accordance with EN 14388.
HB Absorber - The CO2 Superpower
PHONOBLOC® wood-concrete absorbers, as used in modern noise barrier walls, are true climate protectors: thanks to the natural carbonation process, they actively bind CO₂ from the air. The porous structure of the wood-concrete promotes the absorption of carbon dioxide, which gets permanently bound within the material. A natural process that is not only effective, but also sustainable. In addition, the wood content in the wood-concrete stores CO₂ during the tree’s growth — allowing PHONOBLOC® HB Absorbers to combine two powerful climate benefits:
✔ CO₂ binding through carbonation
✔ Long-term CO₂ storage through the wood content
PHONOBLOC® HB Absorbers reduce not only noise, but also CO₂ – for a smaller ecological footprint. Noise protection meets climate protection – with real CO₂ superpower.
