The nature screen

67% lower climate footprint than competing noise screens. At the same time, the Nature Screen is a unique, green opportunity to aesthetically shield people and nature from modern road construction, made of asphalt, steel and concrete. The screen is available with a wide selection of facades: live willow, which changes color with the season, or debarked and heat-treated willow, which patinas and turns steel grey. The design with the braided facades in raw logs has been developed by PileByg, and given the green light by being type-described by the Road Directorate as NATURE SCREEN. It can be combined with common solutions such as transparent facades – or noise fences built in steel and wood. PileByg’s noise barriers 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 through the entire process, from choosing the best solution to complete delivery and installation. The facades can be combined as desired; they are not structurally load-bearing, they are the framework. The very core of noise-absorbing stone wool is self-supporting. All screens are CE certified according to EN 14388. Supplied as prefab elements or for flexible assembly. We offer free viewing on site.

Classic wooden screen

German quality. 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 effective way to direct moisture away from the wood so that their noise screens 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 fir, oak, bilinga and other FSC-certified woods. Everything Fahlenkamp produces is made in Germany with high quality control on all parts of the noise shield. Read more about the classic wooden noise screen from Fahlenkamp here.

Climate noise screen

The climate screen is a noise screen with a built-in LAR function (Local Drainage Of Rainwater). It is designed to deal with cloudburst problems, for example rain from the city’s roofs, which can be directed down into the core of the screen, where the water is stored and evaporates.

The climate screen is built according to PileByg’s CE-certified principle for natural noise screens – and it therefore isolates and absorbs noise like a regular noise screen. LAR solutions are usually space-consuming and/or must be placed underground. The climate screen is therefore an ideal solution in the dense city. The screen can also be thought of as urban renewal – read more about the climate screen here

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

Graffiti

A nature-like and rough, uneven facade does not encourage graffiti, and experience shows that where graffiti has been attempted on PileByg facades, the vandal has given up. It does not work to paint on the willow braid. The paint disappears into the raw facade. Experience also shows that the natural aging of the facade, which is part of the unique design of PileByg noise screens, ensures that graffiti is eroded away by wind and weather.

The natural screens have a 67% lower climate footprint than conventional noise screens and they require minimal or no maintenance. The screen’s statics are calculated on the basis of steel and acacia in a sandwich construction, where the facades patina with the grace of nature. Whole logs patina differently than cut wood; for example, planks and slats where the wood has been cut (the wood fibers have been cut/opened) will have cracks and fissures that call for wood protection. The willow trunks have an unbroken surface and no truncated wood fibers. Therefore, they patina and age beautifully, without the use of chemicals.

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

67% lavere klimaaftryk end  konventionelle støjskærme og produceret i 100% genanvendelige materialer.

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 placement of a noise barrier will most often take place in contrast to neighbours/residents, road or lane. However, it is important to place the noise shield as close to the noise source, or as close to the house as possible. This achieves the greatest noise attenuation using the noise screen.

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 be clearly audible, while a reduction of 10 dB(A) will be perceived as halving the noise level. Attenuation of 5-10 dB(A) is relatively easy to achieve with a ROCKWOOL® stone wool core. Noise attenuation or sound attenuation is expressed in noise isolation value and shielding effect. A noise screen must not allow sound to pass through the screen. However, it is next to impossible to achieve a 100% soundproof noise screen. Therefore, it is sufficient that the noise that passes through the noise screen is negligible compared to the noise that passes over the noise screen.

The noise that passes through the screen must per definition have no effect on it

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.
