Custom sound walls for garden, business and padel

Kokowall is a modular, plantable sound barrier with an exterior of natural coconut fibre wrapped around recycled ABS tubes. The panels are built as a sandwich construction: two rows of sound-absorbing coconut tubes with a sound-insulating core in between. This allows Kokowall to combine high absorption (DLα up to 12 dB, cat. A4) with an insulation value of Rw 30 dB, placing it in the highest insulation class B3 according to EN 1793. Thanks to its light weight of approximately 25 kg/m², a narrow foundation is sufficient, and the barrier can be installed quickly, even in locations where concrete barriers or earth berms are not feasible. The natural coconut fibre also provides an ideal surface for climbing plants, allowing the barrier to become fully green within a few years. Kokowall is produced in accordance with CE standard EN 14388 and is treated with FR Firestop C26 for fire retardancy.

The Noise-Reducer is a modular sound barrier made of steel and mineral wool. Specifically designed for industrial applications requiring maximum sound insulation, such as battery energy storage systems (BESS), transformers, cooling units, and production halls. The system is quick to assemble, weather-resistant, and can also be used for temporary applications (construction sites, events).

If you want to soften the industrial look of steel in a garden or residential setting, choose Noise-Reducer Wood. A front of thermally treated wood, on one or both sides, applied to the standard SA and DA panels. The acoustic performance is fully preserved.

The Ichono Wall panel is the perfect solution for those who want to combine acoustic comfort with a sleek finish that integrates seamlessly with the rest of the architecture. Thanks to its smart construction, this panel offers excellent noise reduction. We can perfectly match it to the colours of the windows and doors. The outer side consists of a robust 0.63 mm steel sheet, while the inner side is finished with a 0.50 mm steel sheet: solid, sleek and easy to maintain. Between the two sheets sits an insulating core of 100 mm rockwool, a natural barrier against noise, heat and cold. The panels are available in standard lengths from 2,000 to 12,000 mm and in a wide RAL colour palette. The exterior can be profiled, micro-profiled, macro-profiled or smooth. Perforation of the inner side is available on request.

Noistop Steel from ROCKWOOL is a modular acoustic fence with a galvanised steel frame, a core of sound-absorbing stone wool and a wear-resistant PE netting finish. The combination delivers 22 dB sound insulation (EN 1793-2, class B2) and 8 dB absorption (EN 1793-1, class A3). The fence is fully maintenance-free, fire-resistant thanks to the mineral stone wool and withstands wind loads up to 2.49 kN/m². Modules slide between galvanised posts in heights of 45 to 100 cm (stackable) and in galvanised steel, anthracite (RAL 7016) or jet black (RAL 9005).

Noistop Wood combines the absorbing power of ROCKWOOL stone wool with the natural beauty of solid pine. The panel achieves 21 dB sound insulation (EN 1793-2, class B2) and 11 dB absorption (EN 1793-1, class A3) thanks to its layered build: a galvanised steel frame, a sound-absorbing stone wool core, protective PE netting and an FSC-certified pine cladding, chrome-free impregnated to use class III (EN 335:2013). Available in three designs (Elba, Ibiza, Sardinia) and in natural or brown-painted slats. Modules 200 cm wide, heights 45, 90 or 100 cm, stackable.

Noistop Essential is the most flexible system in the ROCKWOOL Noistop range. The base is a galvanised steel frame with a sound-absorbing stone wool core and PE netting. On each side, you independently choose between a steel finish (galvanised, anthracite RAL 7016 or black RAL 9005) or an FSC-certified pine cladding (natural or brown RAL 8003). Ideal when you and your neighbour have different aesthetic preferences. Acoustic performance: 18 dB insulation (class B2) and 9 dB absorption (class A3) according to EN 1793.

Greenwall Classic is a patented, foundation-free sound barrier made of trapezoidal prefab elements. The steel cage is wrapped in coir cloth and filled with a unique hemp-wood fibre that combines high sound insulation (33 dB) and absorption (11 dB) with rapid greening through climbing plants. Its light weight and stable trapezoidal profile remove the need for foundations, drastically cutting build time and cost. Available in heights from 180 to 300 cm, ideal as a green barrier between public space and residential zones.

Greenwall Cassette is a modular sound barrier made of slim panel-shaped elements. The steel cage is wrapped in reinforced natural fibre cloth and filled with hempcrete, an organic blend of lime and hemp-wood fibres. The combination delivers 27 dB insulation and 6 dB absorption (NL Greenlabel A). Its narrow profile suits schoolyards, cemeteries, gardens between neighbours and hard-to-reach locations. Stackable up to 4 m high. Available in elements of 2 or 4 m length.

Greenwall Construct is the highest-performance system in the Greenwall range. On a stable subsoil, hot-dip galvanised steel A-posts are placed and connected, then mesh grids and netting are fitted and the structure is filled with the Greenwall substrate. The ratio between base width and height allows foundation-free placement up to 8 metres. Acoustic performance: 42 dB insulation (class B3) and 12 dB absorption (category A4). Suitable for motorways, railways, public roads and industrial sites. Not for private gardens.

The transparent sound barrier is installed where views and natural light are crucial: in front of windows, on terraces, along balconies, or as the top section of a taller sound barrier. Made from impact-resistant PMMA or toughened safety glass with UV protection. Often combined with markings or patterns to prevent bird collisions.
