Noise barriers

Ramea Green barriers offers several types of noise barriers depending on the needs of the project in order to offer an ecological and sustainable solution to noise and visual pollution problems.

How are our walls designed ?

Ramea noise barriers are made of natural and durable materials. Our screens are made of sturdy galvanized steel rods, larch, acoustic rock wool and large diameter willow rods. They will last over the years without losing their brilliance, mechanical strength or acoustic performance.

Tested and proven technology, our products are designed to meet the most stringent standards and requirements in terms of quality and technical performance.

Ramea green barriers solutions are maintenancefree and offer a long lifespan. The wood will turn gray over time and climbing plants will give hints of green orred according to the seasons.

Facades design

 

In order to meet the needs of your project, our products offer a wide choice of facades.You can choose from our dried willow products (with or without bark), larch or wire meshDried willow requires almost no maintenance.

For a more economical option, you can choose a larch or wire mesh covering.

Benefits and statistics

More effective than concrete… Really ?

A noise barrier solution must reduce noise for a given area. However, it is important not to amplify the noise on the opposite side of the barrier with sound reflection. In the case of reflective concrete walls, the noise level can sometimes INCREASE by 3 dBA.

Studies show that our solutions absorb 95% of the noise, blocking it without reflecting it.

How big should your noise barrier wall be ?

The height and length of the wall have a major influence on the effectiveness of your sound barrier. The higher the wall is, the more effective it will be. In addition, you will have to install your wall over a longer distance than the area to be protected, otherwise the sound may bypass the limits of your wall.

The insulating element and acoustic properties

Our walls are insulated with Rockdelta rock wool specially designed for outdoor conditions.

Rock wool offers incomparable acoustic properties. We offer two wool density: 13 kg/m² and 21 kg/m². We can therefore adjust to your specific needs. If necessary, if you require densitabove our standards, please contact us.

Ramea green barriers meet European CE conformity standards as well as North American ASTM standards. Our noise barriers have been tested by DELTA ( www.madebydelta.com) and Intertek (www.intertek.com), leaders in the testing and control industry.
