Summary
The INSA AL ROCK concrete noise barrier is designed to provide a highly durable and effective noise control solution, especially in environments with high structural and resistance requirements. Thanks to its solid construction, it is ideal for projects requiring stable and long-lasting acoustic protection against adverse weather or high-impact situations.
This model consists of a dual-layer system combining functionality and strength: a load-bearing layer of reinforced conventional concrete, adding rigidity and robustness to the structure; and a sound-absorbing layer of porous concrete, which captures and reduces environmental noise through its sound-permeable structure.
The high density of the assembly delivers notable sound absorption along with moderate sound insulation, making the INSA AL ROCK a versatile solution for roads, railway lines, and industrial zones. Its robust design ensures a long service life with minimal maintenance, making it an efficient and cost-effective long-term choice.
