Noise barriers

Continuous economic progress is increasing the risks in the human environment. Noise barriers are built to protect against noise, exhaust fumes and dust. Nowadays, the following requirements are placed on noise barriers: sound insulation, sound absorption, guaranteed lifespan and aesthetic considerations to integrate these elements into the landscape. We offer acoustic screen panels, manufactured on the basis of the technical solutions for aerated concrete screens contained in Betard's licence from Liadur. Liadur acoustic panels consist of two layers, joined together in the prefabrication phase, i.e. a 12 cm thick reinforced concrete structural slab and a layer of expanded clay concrete of a thickness and shape depending on the required acoustic absorption class. The sound-absorbing wall system we offer is not only characterised by its high acoustic effectiveness, but also ensures easy installation, inexpensive maintenance and high durability thanks to its design solutions. In addition to sound-absorbing panels, for the realisation of noise barriers we offer foundation beams and reinforced concrete columns, as well as emergency exit elements. We produce panels with lengths of L= 4-5m (maximum L=6m). The heights of the individual panels are 1.5m, 1.0m and 0.5m
