Noise Barriers


Permacrib Environmental Noise Barriers

As highways, airports. railways and industries encroach deeper into the residential and commercial areas of our cities there is a growing call for effective and environmentally attractive noise protection systems. Permacrib Noise Barrier offers a cost effective system that has exceptional acoustic performance and a unique natural appearance.

Technical development of Permacrib Noise Barrier followed comprehensive acoustic testing carried out by independent ISO registered laboratories in New Zealand and Finland. Test results confirm that Permacrib can reduce Noise Transmission by up to 30dB and more importantly, with a Noise Absorption Coefficient of 0.80 Permacrib Noise Barrier actually absorbs noise rather than reflecting it. Less absorbant concrete, steel and plastic noise barrier systems reflect sound back to the source and will often result in even higher noise levels opposite the barrier.
