Noise insulation and noise absoprtion.

Acoustic barriers and sound barriers

Our range of acoustic barriers combines class leading acoustic performance with environmental and sustainable credentials second to none.

The Green Barrier – awarded design

The acoustic barriers from PileByg are the only green barriers which are fully CE marked. They are engineered for durability, strength and attractiveness. They are chosen for both their effectiveness and appearance. The barriers make out an ideal screening to ensure that people and their surroundings are shielded from the noise and pollution caused by todays heavy traffic. You can choose between a wide range of facades such as living willows, which will change colors according to the season; woven facades in willow with or without bark, or non-woven and heat-treated facades, which will patinate an go grey with a smooth and bright surface. The Green Barrier concept for sound barriers are developed by PileByg and is now categorized by the Danish Road Directorate as the Natural Barrier. PileByg facades can be delivered combined with more conventional facades such as transparent facades og steel mesh and wood cut wood panels. The Green Barrier concept has been awarded with the Danish Design Award.

Delivery and mounting of acoustic barriers

We are at your service from the moment you have to choose the right solution, both technically, aesthetically - and until finished mounting on site. Depending on the location and noise problems on site, we will either recommend the BASIC+ Concept or the CLASSIC Concept. The selection of facades can be combined individually to either concept as the facades has no bearing part of the construction. They are simply woven or built into the bearing frames of the barriers. The cores is always a self-supporting mineral wool with excellent soundabsorbing features. . All barriers carries a CE-certificate according to EN 14388. Our barriers can be delivered either as readymade prefab elements or as elements for flexible installations fitted for the specific site. Contact us for more information. We offer free advice and site-inspection.

Life Cycle Analysis is the key to a sound solution. That's why our barriers is a sustainable choice, economycally and environmentally.

The Green barriers from PileByg requires a minimum of maintenance – or none. The barriers are built as a sandwich construction where the structural bearings are made from steel and hard wood, and the facades of willow hold no structural properties. The willow facades are simply an attractive way of ensuring a long-lasting façade which requires no maintenance; the whole rods will go old more delicately than cut wood. Panels and planks of wood has an open surface, and they will soon show cracks and often require treatment. The use of whole stems offers therefore a clever shortcut to an environmental sustainable strategy of maintenance; and it is a good example of how we in PileByg try to pursue the 17 UN Sustainable Development Goals through development of clever designs.

Generelle specifikationer


CE-certified according to EN 14-388 (as required by EC-legislation since 2007).


Noise insulation and absorption is the ideal combination to ensure maximum value of an acoustic barrier, especially as the noise is not reflected.


An sustainable design with minimum carbon footprint and 100% recyclable. A strong set of environmental credentials to any developer.


No costs for cleaning or wood treatment - or chemicals to remove graffiti.


The green barriers are designed with facades which gracefully go old – like nature itself, they only become more beautiful with age.


From 26 til 36 years of life expectancy on all parts of the green barrier; The CLASSIC barrier concept having the longest life expectancy

The most efficient noise abatement of outdoor noise along highways, roads and railways is to install acoustic barriers.

PThe exact location of an acoustic barrier will usually take place in a divide against the neighbor and the road or track. However, it is important to place the noise barrier as close as possible to the noise source, or as close to the house as possible. This achieves the greatest noise reduction by means of the acoustic barrier.

Noise is measured in the unit dB (A). The noise level on a main road in the city (50 km / h), with 4,000 cars per. day, is approx. 63 dB (A) measured 10 meters from the center of the road. A reduction of 5 dB (A) will clearly be heard, while a reduction of 10 dB (A) will be perceived as halving the noise level. Attenuation of 5-10 dB (A) is relatively easily achievable with a mineral wool cores as applied by PileByg. Noise suppression or silencing is expressed in noise insulation value and screen effect. A noise screen must not allow the sound to pass through the screen. However, it is virtually impossible to obtain a 100% soundproof noise screen. Therefore, it is enough that the noise passing through the noise barrier is negligible in relation to the noise passing over the noise barrier.

In addition to dampening the noise on its own, it is important not to add extra noise nuisances as a result of sound reflections. If the sound is thrown back from the noise screen, it must be added to the noise level that already exists in the repository. This often means an increase of approx. 3 dB (A), which immediately does not sound violent, but in reality it is perceived as doubling traffic. The absorbtion aspect of the Green barriers is therefore crucial.
