Frequently asked questions

We have answered most of the questions that may have been asked about our noise barriers and our fences.

Why should your noise barriers be greened?

Façade planting provides a number of environmental benefits. It helps manage rainwater, and the evapotranspiration effect of plants helps regulate temperature, reduce the heat island effect and improve air quality by capturing CO2.

In addition, plant façades contribute to biodiversity by acting as ecological corridors, helping to counteract the fragmentation of habitats caused by urbanization (Earth Pledge, 2005).

On the other hand, vegetation enhances the quality of life of occupants and creates a sense of well-being. Contact with a natural landscape has beneficial effects on human health, such as reducing stress and aggression, lowering blood pressure, relaxing muscular tension and increasing positive feelings such as calm (Urich and Simons, 1986; Velázquez, 2005).

Finally, climbing plants help extend the life of infrastructure by protecting it from the elements, particularly rain and UV rays.

Are willows alive?

In our experience, the optimum conditions (sun, water, nutrients) to ensure the longevity of live willow are often difficult to achieve for this type of infrastructure. What’s more, live willow requires maintenance that is often undesirable for this type of structure.

For this reason, Ramo instead uses facades incorporating dried willow stems, which act as a carbon sink and stake for climbing plants. Over the years, the screen will be covered by the climbing plants, giving it the virtues of a vegetated infrastructure while maximizing durability and minimizing maintenance.

An ecological noise barrier?

Our products are designed to limit their ecological footprint. The materials used in the manufacture of our products are durable, natural, recyclable, maintenance-free and mostly sourced locally. The wood used in manufacturing will have captured and sequestered a significant amount of carbon, making the products low-carbon.

What’s more, Ramo applies best design practices to achieve life expectancies comparable to, if not better than, more traditional materials.

How long have you been making green barriers?

Ramo manufactures its products under exclusive license from Pilebyg (Denmark) and Heinrich Fahlenkamp GmbH & Co (Germany).

Pilebyg has been designing and manufacturing willow noise barriers for over 25 years. Heinrich Fahlenkamp GmbH & Co. has developed and patented a unique technology which, for over 40 years, has made it possible to offer a product with outstanding durability.

Through these partnerships, Ramo ensures that its products are proven, durable and high-performance. Since 2006, Ramo has manufactured and installed dozens of kilometers of noise barriers in Quebec, Ontario and the United States.

Are your noise barriers effective in reducing noise?

Our products have been tested and certified to ASTM E90, E413 and C423 standards. Our products meet the highest industry standards, as well as those of the Ministère des Transports et de la Mobilité durable du Québec (MTMD).

Consultation with an acoustician enables us to design the noise barrier in compliance with height, length and location requirements, as well as the noise barrier’s characteristics (surface density, STC, NRC) to meet noise mitigation needs. In fact, we work with all firms specializing in acoustics.

Can your wall catch fire?

Historically, in our experience and that of our Danish and German partners, no project has been exposed to major fires. Although wood has flammable properties, the propagation index is relatively low due to the materials used in the design. In addition, rock wool acts as a retardant and steel posts limit propagation.

Why use willow in your barriers?

Willow grows extremely fast, reaching up to 5 meters in height in three years. During its growth, it absorbs and sequesters a large quantity of CO2, which benefits the carbon balance. What’s more, once cut, it regenerates with its root system, which remains in the soil. It’s a virtually infinitely renewable source of raw material!

What maintenance is required for the wall?

No maintenance is required. All the materials used are maintenance-free.

Will the wood rot?

Wood has been used in building construction and road infrastructure for hundreds of years. Bridges, farm buildings, guardrails and telephone poles are all part of our landscape. Thanks to the use of durable species and the judicious integration of wood components, it is possible to achieve a long product life expectancy. The primary enemy of wood is moisture, which is why Ramo applies sustainable design best practices such as :

Adding a protective metal cover to the top of the screen.

Techniques to minimize contact between pieces of wood

Design to limit rising soil moisture.

Design to ensure water and moisture drainage.

Layout and profiling of wood parts.

Use of galvanized steel structural components.

Integration of climbing plants to reduce degradation by UV rays and rain.

I'd like a natural noise barrier. What do I need to do?

If you are an individual, please contact one of our distributors/installers.

If you’re a professional, please contact us and our team will help you with your project.

Where can I get prices for willow fencing?

Consult the list of our distributors/installers by region.

Do your products withstand winter conditions?

Our products are designed to withstand the harsh winter conditions encountered in Quebec and elsewhere in North America. What’s more, wood is highly resistant to salt footprints. It’s important to pay particular attention to layout and elevation when designing, as wood panels are not designed to withstand projections, such as from a snowplow. However, we believe that it is entirely feasible to design screens close to highway curbs, with adequate elevation on a concrete base. It’s important to note that our products have a long history in Europe, particularly in Scandinavia, which is exposed to climates similar to those in North America.

Is willow wood less durable than traditional fence wood?

According to the literature, willow is not as durable as cedar or oak, for example.

The primary enemy of wood is humidity, which is why Ramo applies sustainable design best practices such as :

Adding a protective metal cover to the top of the screen.

Techniques to minimize contact between pieces of wood

Design to limit rising soil moisture.

Design to ensure water and moisture drainage.

Layout and profiling of wood parts.

Use of galvanized steel structural components.

Integration of climbing plants to reduce degradation by UV rays and rain.

What’s more, our unique debarking process gives the willow an extremely smooth surface, making it very difficult for water to penetrate, unlike a piece of wood that would have been sawn or debarked using an abrasive process.

Last but not least, willow stems are mechanically braided without fasteners or fixings to limit entry points for moisture.

 

Does Ramo do the installation?

Ramo Green Barriers does not offer installation services, but we do have certified installers in Quebec, Ontario and Alberta. Installation is simple and can be done by a general contractor.

What size are the fence panels?

The standard width of our panels is 5 feet. Panels can easily be shortened if required. We can also manufacture custom panels up to 8 feet wide. The standard height of our panels is 6 feet, but we can manufacture custom panels up to 11.5 feet high. Please note that panels can be stacked for heights greater than 11.5 feet. Panel thickness is approximately 5 inches.
