Kohlhauer LIGNA

High quality timber noise barriers from treated pine (other woods are available upon request) as a highly sound absorbing or sound reflective version. The elements are CE-certified and correspond to EU standards. The elements are to be mounted between pre-installed posts; in piling pipe, concrete sleeve or auger pile foundations. Wall heights up to 6 m are feasible.

Application

Noise barriers made of wood offer special design possibilities, have an excellent ecological balance (CO - neutral) and make an important contribution to relieving the strain on the environment and saving on resources.

Benefits

• Slightly green colour shade
• The impregnation is environmentally friendly and persistent
• As a result of its resistance to deicing salt, no post-treatment is required
