The Green Barrier – awarded design

Our range of acoustic barriers combines class leading acoustic performance with environmental and sustainable credentials second to none. The screen is available with a wide range of facades: living arrow that changes color with the season, or debarked and heat-treated arrow that patinates and becomes steel gray. The design with the braided facades in raw trunks has been developed by PileByg, and the blue stamp is being type-described by the Danish Road Directorate as NATURSKÆRMEN. It can be combined with common solutions such as transparent facades – or noise fences built in steel and wood. PileByg’s noise screens have been awarded the DANISH DESIGN AWARD. PileByg’s noise screens are also available as PREFAB, so installation is quick and efficient. We are ready to help throughout the entire process, from choosing the best solution to finished delivery and assembly. Depending on the requirement for the location and service life of the noise screen, the screen is supplied as a BASIC + or CLASSIC noise barrier. The facades can be combined according to the desired design; the facades are not load-bearing, but the frames are. The very core of noise-absorbing rock wool is self-supporting. All screens are CE-certified according to EN 14388 Supplied as prefabricated elements or for flexible mounting. We offer free inspection on site.

The Green Barrier – awarded design

Fahlenkamp has more than 150 years of experience with wooden constructions and makes some beautiful noise screens with high quality wood. Thanks to their many years of experience with wood, they have found an invisible and efficient way to direct moisture away from the wood so that their noise barriers require minimal to no maintenance. Their oldest screen still stands nice and beautiful where it was set up more than 25 years ago, and is expected to stand well for the next many years. Fahlenkamp noise screens can be produced with pine, larch, douglas, oak, bilinga, and other FSC-certified woods. Everything Fahlenkamp produces is made in Germany with high quality control on all parts of the noise barrier. Order your Fahlenkamp noise screen here.

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 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 willows has an even surface and no short fibres This makes a natural patina without the use of chemicals.

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.

General specifications

01

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

02

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

03

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

04

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

05

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

06

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.

The 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. 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. The noise isolation (reduction of noise through the screen) should be approx. 10 dB (A) higher than the screen effect (total attenuation). In other words, if you want to reduce the total noise by 10 dB (A), the noise that passes through the screen must be reduced by a minimum of 20 dB (A).

In addition to attenuating the noise on your own grounds, it is important not to add extra noise to neighbors / neighbors due to 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. Which means; the noise is not reflected back, but is muted in the screen.
