Noise Barriers
Six material systems for road, rail, industrial and logistics projects, each available reflecting or absorbing. We help you select against the requirement, then supply the system that meets it.

Six Systems, Selected for the Project
Every system is available reflecting or absorbing. The requirement decides the material; the material decides weight, foundations, transport, maintenance and carbon.
RMP Recycled Noise Barriers
Rotationally moulded panels from recycled polyethylene. Twelve designs, any RAL colour, reflecting or absorbing.
Transparent Noise Barriers
Acrylic, polycarbonate, glass and window-framed systems where the view has to stay open.
Aluminium Noise Barriers
500 mm standard cassettes, absorbing on one or both sides. Adding solar units is an option.
Concrete Noise Barriers
Reflecting or absorbing faces in wood fibre, Miscanthus or porous concrete.
Green Noise Barriers
Planted mineral wool elements that disappear into the landscape.
Gabion Noise Barriers
Stone, lava, soil or RMP element fill in a galvanised cage.
How to choose
Three Acoustic Questions, Then the Material
Absorb, insulate or see through sets the family. Material choice then decides weight, foundations, transport, maintenance, lifecycle and carbon. The barrier is not only an acoustic decision.
Absorb
Stop reflections back across the road or to the other side. RMP Recycled, concrete, aluminium, green and gabion systems.
Insulate
Stop sound passing through to the people behind the barrier. RMP Recycled, concrete, aluminium and transparent systems.
See Through
Keep the view, daylight or sightlines. Acrylic, glass, polycarbonate and window-framed systems.
A fence is not a noise barrier. Fencing is not developed for noise reduction; Acoustic Fencing uses the same tested element as a boundary.

Why noise barriers
Noise Is a Health Issue, Not a Nuisance
Health organisations, including the WHO in its 2018 Environmental Noise Guidelines, link long-term traffic and industrial noise to sleep disturbance and stress. A noise barrier removes that exposure, permanently or for the life of a project, for the people who live and work beside the source.
