Summary
The INSA RA ROCK stands out for its higher sound insulation capacity compared to other models in the range, making it a preferred choice for residential areas sensitive to noise or infrastructures requiring more efficient sound containment. Its high density also allows for notable sound absorption, providing comprehensive noise control through both reflection and transmission reduction.
The INSA RA ROCK concrete noise barrier has been developed to deliver exceptional durability combined with superior acoustic performance, particularly in terms of insulation. It is ideal for demanding environments where blocking noise effectively is as important as maintaining high structural strength over time.
This model is composed of two distinct layers: a reinforced conventional concrete base, providing mechanical stability and robustness against loads and adverse environmental conditions; and a porous concrete sound-absorbing layer, effectively attenuating incident sound thanks to its permeable structure.
Its robust design and acoustic efficiency make this barrier a safe, durable, and highly functional option for long-term projects.
